Sidebar PHP returns error
 
Hello,

I was trying to put a PHP code to the sidebar and an error occurs that says

Code:
Parse error: syntax error, unexpected '<' in /home3/xxxxxx/public_html/forum/includes/block/html.php(95) : eval()'d code on line 1
The code is basically using the get content method from another website, here is the code I am using:

PHP Code:
<?php

    $url = "http://www.uta.edu/uta/acadcal.php";

    
    
    function get_url_contents($url){
        $crl = curl_init();
        $timeout = 5;
        curl_setopt ($crl, CURLOPT_URL,$url);
        curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout);
        $ret = curl_exec($crl);
        curl_close($crl);
        return $ret;
    }
    
    $str = get_url_contents($url);
    
    // popular people
        $explode = explode('<div class="column_body">', $str);
        $explode = explode('<div id="column_right">', $explode[1]);
        $explode = $explode[0];
        
    // prase semester
        preg_match_all('/<h3>([^`]*?)<\/h3>/', $explode, $semester);
        $semester = $semester[1][0];
        
    // prase events
        preg_match_all('/<td width=\"15%\"> <strong>([^`]*?)<\/strong>/', $explode, $date);
        preg_match_all('/<td width=\"81%\">([^`]*?)<\/td>/', $explode, $event);

?>

<table style="width: 100%">
    <tr>
        <td colspan="2"><strong><?php echo $semester; ?></strong></td>
    </tr>
    
<?php

foreach (array_combine($date[1],$event[1]) as $date =>$event) {
 ?>

     <tr>
        <td><?php echo $date; ?></td>
        <td><?php echo $event; ?></td>
    </tr>

 <?php
}

        
        
?>
What should I do?

You can't use PHP like that in the template system. your widget is super invalid.

Any alternatives?

The following reference will help you. You should Google vbulletin.org for further references -- you will find many. :)

If you're creating a forum block, you would want to choose "php" as the type, then you should be able to use php. But your php would have to "return" the html as a string instead of outputting it like your code is doing. You could solve that by using ob_start()/ob_end() like in the links tbworld provided, or you could just rewrite the code to build a string instead of using ?> and <?php to include html.
