Help Search a String inside a CURL variable!!

[jigen7]

hi I'm having trouble with this one what i want to do here is that i want to know if a webapge contains the specific string that i've inputted so i do this like this

function search_call($url,$search_criteria){
$size = 0;

$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// grab URL, and return output
$output = curl_exec($ch);

// close curl resource, and free up system resources
curl_close($ch);
echo $output;
if (eregi($search_criteria, $output)) {
    $size = 1;
}

 

the problem here is that sometimes it returns that the string is not found. but when i went to the actual site and use the ctrl+f i'll see that it actually contains the actual string.. anyone have better idea doing this?? thx

$beg_pos = strpos($this->pageSource,"$before");
$end_pos = strpos($this->pageSource, "$after", $beg_pos);
$this->pageSource = substr($this->pageSource, $beg_pos, $end_pos - $beg_pos);

you could also use perl regex

preg_match("<img border=\"0\" alt=\"\" src=\"(.*)\" />", $this->pageSource, $var);
