Is there any way to keep a count of tweets containing a specific hashtag or word? For example, keeping a count of all tweets containing the hashtag, #apple, or all tweets containing 'iphone'?
this php source code for get count hashtag(#) twitter
<?php
global $total, $hashtag;
//$hashtag = '#supportvisitbogor2011';
$hashtag = '#australialovesjustin';
$total = 0;
function getTweets($hash_tag, $page) {
global $total, $hashtag;
$url = 'http://search.twitter.com/search.json?q='.urlencode($hash_tag).'&';
$url .= 'page='.$page;
$ch = curl_init($url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
$json = curl_exec ($ch);
curl_close ($ch);
//echo "<pre>";
//$json_decode = json_decode($json);
//print_r($json_decode->results);
$json_decode = json_decode($json);
$total += count($json_decode->results);
if($json_decode->next_page){
$temp = explode("&",$json_decode->next_page);
$p = explode("=",$temp[0]);
getTweets($hashtag,$p[1]);
}
}
getTweets($hashtag,1);
echo $total;
?>
Thanks..
You could use a service like DataSift to keep track of Tweets containing certain hashtags or keywords in real time. They will also be releasing a Historics service this summer, allowing you to search back as far as January 2010

I want to get last 50 videos from www.youtube.com/feeds/videos.xml?playlist_id, Currently I can only retrieve last 15 videos. I have tried max-result parameter, but it failed.
Instead of above method I have found another way to fetch youtube playlist videos, here it is
<?php
$playlistId = 'Playlist Id here';
$maxResults = 50;
$apiKey = 'youtube api key here';
$string = json_decode(file_get_contents('https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId='.$playlistId.'&maxResults='.$maxResults.'&key='.$apiKey.''));
//echo '<pre>'; print_r($string);
foreach($string->items as $item) {
$video_id = $item->snippet->resourceId->videoId;
}
?>
I've got some problems with my url on my website. I'm trying to get a link with the given GET parameters, but i'm getting my previous parameter aswell.
My url looks like this:
www.cdwinkel.dev/search-results?genre=Pop&medium=DVD&medium=Single .
It should be:
www.cdwinkel.dev/search-results?genre=Pop&medium=Single .
I'm running the following code:
$data['url'] = createurl();
function createurl(){
$i = 1;
$string = "?";
$keys = array_keys($_GET);
foreach($_GET as $get){
if($get != ""){
$string .= $keys[$i] . "=" . $get ."&";
$i++;
}
}
$string = rtrim($string, "&");
return $string;
}
$i = 1, because my first value in my array is empty.
And my button looks like this:
<a href='".$data['url'].'&medium='.$names[$i]."'>
I guess I should'nt set &medium=.$names[$i] in the href tag,
but I wont get the new $names[$i] in my function, so I won't get a new url if i wont add it in.
I'm looking forward to your responce.
Sincerely,

At this point i've created an array with the right arraykeys and values.
$url = array_slice($_GET, 1);
This returns the following array:
array (size=2)
'genre' => string 'Pop' (length=3)
'medium' => string 'DVD' (length=3)
After this I decoded this into a new string:
genre=Pop&medium=DVD
I got 6 button which I created in a foreach loop, but i'm getting &medium='VALUE' Twice. This only happens after the first time. So the first time my button works well.
<?php
$names = array_keys($data['tellen']);
$i = 0;
foreach($data['tellen'] as $m){
echo "<li><a href='search-results?".$data['url'].'&medium='.$names[$i]."'>". $names[$i] ." <span class='product-amount'>(". $m[0]->count. ")</span></a></li>";
$i++;
}
Hopefully you can help me further with this information.
I solved my problem by adding this in my forloop:
foreach($data['tellen'] as $m){
if(isset($_GET['medium'])){
unset($_GET['medium']);
$url = array_slice($_GET, 1);
$data['url'] = urldecode(http_build_query($url));
}
echo "<li><a href='search-results?".$data['url'].'&medium='.$names[$i]."'>". $names[$i] ." <span class='product-amount'>(". $m[0]->count. ")</span></a></li>";
$i++;
}
I've been able to parse a PDF by page multiple ways, the latest being this (not my code):
$reader = New-Object iTextSharp.text.pdf.pdfreader -ArgumentList "oldy.pdf"
for ($page = 1; $page -le $reader.NumberOfPages; $page++)
{
$strategy = new-object 'iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy'
$currentText = [iTextSharp.text.pdf.parser.PdfTextExtractor]::GetTextFromPage($reader, $page, $strategy);
[string[]]$Text += [system.text.Encoding]::UTF8.GetString([System.Text.ASCIIEncoding]::Convert( [system.text.encoding]::default, [system.text.encoding]::UTF8, [system.text.Encoding]::Default.GetBytes($currentText)));
}
I found a post here that suggested using LocationTextExtractionStrategy instead and splitting each line out by '\n'
However, I will admit that the .NET code here is confusing me and i'm not sure how to modify it to parse by string.
Can anyone help?
thanks.
Only a first experiment, but it works as expected:
# Download http://sourceforge.net/projects/itextsharp/
Add-Type -Path itextsharp.dll
$reader = New-Object iTextSharp.text.pdf.pdfreader -ArgumentList MyFile.pdf
for ($page = 1; $page -le $reader.NumberOfPages; $page++)
{
# extract a page and split it into lines
$text = [iTextSharp.text.pdf.parser.PdfTextExtractor]::GetTextFromPage($reader,$page).Split([char]0x000A)
Write-Host "Page $($page) contains $($text.Length) lines. This is line 5:"
Write-Host $text[4]
#foreach ($line in $text)
#{
# any tasks
#}
}
$reader.Close()
I'm trying to figure out how to get the page name from a facebook page and although I've figured out how to get it from the http://www.facebook.com/pagename version, I can't figure out how to test and get it from the longer version that looks like this http://www.facebook.com/pages/pagename/433425324544. How can I test to see if the path starts with /pages and how can I extract the pagename from it all using one function. Here's what I use to get the page name in the standard form.
function get_facebook_username( $facebook_url ) {
$url = $facebook_url;
$result = preg_match("/(https|http)?:\/\/(www\.)?facebook\.com\/?([^\/]*)/", $url, $matches);
$fb_username = 'default value';
if($result == 1){
$fb_username = $matches[3];
} else {
return;
}
echo "$fb_username";
}
I found a better way to do this I think except it cuts the last letter off the username if the url is in it's shortened version. For example.
//---short
$url = http://www.facebook.com/pagename
//---long
$url = http://www.facebook.com/pages/pagename/7532527927346
<?php
$url = $facebook_username;
$path = parse_url($url, PHP_URL_PATH);
$pathTrimmed = trim($path, 'pages/../0123456789');
echo $pathTrimmed;
?>
//---short
pagenam
//---long
pagename
Why is the short version missing the last letter?
The way I would go about this is to use explode to place the url into an array using the below code:
$url = "http://www.facebook.com/pages/pagename/7532527927346";
$result = explode("/", $url);
You get the following array:
array(6) {
[0]=>
string(5) "http:"
[1]=>
string(0) ""
[2]=>
string(16) "www.facebook.com"
[3]=>
string(5) "pages"
[4]=>
string(8) "pagename"
[5]=>
string(13) "7532527927346"
}
Then a simple if $result[3] == "pages" will allow you to check if the url contains pages.
Ninja Edit
In place of explode, you can also use the preg_split which will return no empty array elements:
$result = preg_split("~/~", $url, -1, PREG_SPLIT_NO_EMPTY);
i have been trying to implement jquery ui autocomplete feature.. and the basic html code is xactly the same as given on-
http://jqueryui.com/demos/autocomplete/#remote
I have tried all combinations/ code snippets for "search.php" such as-
1)
<?php
if ( !isset($_REQUEST['term']) )
exit;
// connect to the database server and select the appropriate database for use
$dblink = mysql_connect('localhost', 'root', '') or die( mysql_error() );
mysql_select_db('research');
$rs = mysql_query('select uname,email,password from login where uname like "'. mysql_real_escape_string($_REQUEST['term']) .'%" order by uname asc limit 0,10', $dblink);
// loop through each zipcode returned and format the response for jQuery
$data = array();
if ( $rs && mysql_num_rows($rs) )
{
while( $row = mysql_fetch_array($rs, MYSQL_ASSOC) )
{
$data[] = array(
'label' => $row['uname'] .', '. $row['password'] .' '.$row['uname'] ,
'value' => $row['uname']
);
}
}
// jQuery wants JSON data
echo json_encode($data);
flush();
?>
2)
<?php
include("includes/connect.php");
$query = "SELECT uname from login WHERE uname LIKE '%" . addslashes($_GET['term']) . "%'";
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result)) {
foreach($row as $val)
$tab[] = $val;
}
print json_encode($tab);
?>
3)
<?php
include("includes/connect.php");
$term = $_REQUEST['m']; // where name of the text field is 'm'
$query = "SELECT * FROM login WHERE uname LIKE '%$term%'";
$result = $mysqli->query($query);
$arr = array();
while($obj = $result->fetch_assoc()) {
$arr[] = $obj['nome'];
}
echo json_encode($arr);
?>
But still nothing is working !! that is when i type into the text box for autocomplete there are no results shown. what could be the error ? are there any alternative solutions ?? Please help !!!
The variable that you pass into json_encode must be an array of strings.
e.g. ["red","green","blue"]
or an array of object literals e.g. [{"value" : "red"},{"value" : "green"},{"value" : "blue"}]
Each time through the loop you need to append the item to the existing items.
I notice, in all 3 code snippets, that you assign the current item to your array variable, instead of appending it. When the loop completes, the only item in your array will be the item processed most recently by the loop.
So unless what you type in the field matches that one item, the autocomplete isn't going to show anything.
Here is my PHP code to build an array of strings before sending it back to the file that made the request.
$fetchedArtists = $db->query($queryToGetArtists );
$json = '[';
$first = true;
while($row = $fetchedArtists->fetch_assoc())
{
if (!$first)
{
$json .= ',';
}
else
{
$first = false;
}
$artist = $row['artistName'];
$json .= '{"value":"'.$artist.'"}';
}
$json .= ']';
echo $json;
