In-depth analysis of the reasons why the file_get_contents function fails to capture content_PHP tutorial

Using file_get_contents to capture the page content is unsuccessful. It may be because some hosting service providers have turned off the allow_url_fopen option of PHP, which means that file_get_contents cannot be used directly to obtain the content of the remote web page. That is, you can use another function curl.
The following are different ways of writing the same function of the file_get_contents and curl functions
Example of using the file_get_contents function:

Copy the code The code is as follows:

< ?php
$file_contents = file_get_contents('http://www.jb51.net');
echo $file_contents;
?>

Example of using curl function:

Copy code The code is as follows:

< ?php
>$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://www.jb51.net');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
