Copy code The code is as follows:
/*
Function: Get the
content on the URL page <br>
<br>
Parameters: $_POST['url'] <br>
*/ <br>
<br>
//Set the longest execution seconds <br>
ini_set ("expect.timeout", 30); <br>
set_time_limit(30); <br>
<br>
// Check URL <br>
if(!isset($_POST['url']) || $_POST['url'] == ''){ <br>
echo "URL error"; <br>
exit; <br>
} <br>
<br>
<br>
/* Get URL page data */ <br>
//Initialize CURL <br>
$ch = curl_init(); <br>
<br>
// Set URL <br>
curl_setopt($ch, CURLOPT_URL, $_POST['url']); <br>
// Let the information obtained by curl_exec() be returned in the form of a data stream instead of being output directly. <br>
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); <br>
// The time to wait before initiating a connection. If set to 0, there will be no waiting <br>
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 0); <br>
//Set the maximum number of seconds for CURL execution <br>
curl_setopt ($ch, CURLOPT_TIMEOUT, 30); <br>
<br>
// Try to get the file content <br>
$store = curl_exec ($ch); <br>
<br>
<br>
// Check whether the file is obtained correctly <br>
if (curl_errno($ch)){ <br>
echo "Unable to obtain URL data"; <br>
//echo curl_error($ch);/*Display error message*/ <br>
exit; <br>
} <br>
<br>
// Close CURL <br>
curl_close($ch); <br>
<br>
<br>
// Parse the <head> section of HTML <br>
preg_match("/<head.*>(.*)</head>/smUi",$store, $htmlHeaders); <br>
if(!count($htmlHeaders)){ <br>
echo "Unable to parse the <head> section in the data"; <br>
exit; <br>
} <br>
<br>
// Get the encoding format set by meta in <head> <br>
if(preg_match("/<meta[^>]*http-equiv[^>]*charset=(.*)("|')/Ui",$htmlHeaders[1], $results)){ <br>
$charset = $results[1]; <br>
}else{ <br>
$charset = "None"; <br>
} <br>
<br>
// Get the text in <title> <br>
if(preg_match("/<title>(.*)/Ui",$htmlHeaders[1], $htmlTitles)){
If(!count($htmlTitles)){
echo "Unable to parse the content of "; <br>
exit; <br>
} <br>
<br>
// Convert the text encoding format of <title> to UTF-8 <br>
if($charset == "None"){ <br>
$title=$htmlTitles[1];
}else{ <br>
$title=iconv($charset, "UTF-8", $htmlTitles[1]);
} <br>
echo $title; <br>
