Help using preg_match to get number of pages (of <a href="javascript: GotoPage(4);" .

[tony007]

Hi all i am trying to use preg_match to get number of pages from a html that has this format :

of <a href="javascript: GotoPage(4);" class="pagingLink">4</a>

in this case i want to grab the number 4 but it never works. Could any one tell me what i am doing wrong ?Hope some one help me .Thanks

global $curl;

// Retrieve number of pages page.
    echo 'Checking friends list... ';
    curl_setopt($curl, CURLOPT_URL, './test.html');
    curl_setopt($curl, CURLOPT_POST, 0);
    $result = curl_exec($curl);
    $headers = curl_getinfo($curl);
    
    // Find out how many pages there are. 
    if (preg_match('~of <a href="(.+?)" class="pagingLink">([0-9]+)</a>~', $result, $matches))
    {
        $pages = $matches[2];
            echo ' Number of pages: $pages ';
        unset($matches);
        
    } 

Html content :

of <a href="javascript: GotoPage(4);" class="pagingLink">4</a>

That works fine here. Are you sure cURL is getting the data?

thanks for your reply. I used print $result; and yes it loaded that remote page. Try to add this url (http://friends.myspace.com/index.cfm...ID==140771218)instead test.html and you can see the full html .Hope i get help getting the number of pages on html of that page.Thanks

Where on earth did 'of' come from?

Thanks for your reply. If you look at your html code that you posted you will find 'of' just before <a hreft= ... almost at the end of the code. But any ways if you look at that page in your browser you see some thing like 1 2 3 4 5 &#187; of 218 prev | next . I wanted to get that 218 but for some reason my doesn't it get the corect value both in firbox and ID :-(

$result = 'blahblahblah <span class="pager_container"><div class="friends_bot" id="nav_bottom"><span class="nav_left"><span class="pgerTitle">Listing 1-40 of 8,702</span><a class="highlight">1</a> <a href="javascript: GotoPage(2);" class="pagingLink">2</a> <a href="javascript: GotoPage(3);" class="pagingLink">3</a> <a href="javascript: GotoPage(4);" class="pagingLink">4</a> <a href="javascript: GotoPage(5);" class="pagingLink">5</a> <a href="javascript: GotoPage(6);" class="pagingLink">&raquo;</a> of <a href="javascript: GotoPage(218);" class="pagingLink">218</a> </span><span class="nav_right"><a class="prevPagingLink disabledPaging">prev</a>  | <a href="javascript: GotoPage(2);" class="nextPagingLink">next</a> </span></div></span>';
if (preg_match('%of <a href="(.+?)" class="pagingLink">([0-9]+)</a>%', $result, $matches)) {
    $pages = $matches[2];
    echo 'There are '.$pages.' pages.';
} 

Outputs:

There are 218 pages.

That works fine for me...

I also tried it with a heredoc of the full page and it worked fine too.

EDIT: I couldn't test cURL but this works too:

<?php
$result= file_get_contents("http://friends.myspace.com/index.cfm?fuseaction=user.viewfriends2&friendID=140771218");
if (preg_match('%of <a href="(.+?)" class="pagingLink">([0-9]+)</a>%', $result, $matches)) {
    $pages = $matches[2];
    echo 'There are '.$pages.' pages.';
}
?>

RudiVisser many thanks for helping me. I tried your first code and it worked for the give result sample data. I tried your second code as it is and number of pages never didn't output!! Infact it scaped the the if statment since even the echo "there are didn't get printed!!


i even used print $result; after $result = curl_exec($curl); and i saw the that page get loaded!! so i concluded that result has the right html!



I am runing this in Apache/1.3.33 (Win32) with PHP version :5.0.4 in local server. Do you think some thing is wrong with version of apache or php ? Hope you help me fix this problem.Thanks

I highly doubt it, but you are using very old software.

When you say pages never outputted, did you try adding an else { }, remember the page could have just been taking a while to load.
