Four Methods for php to call a remote url-php Tutorial

Php calls the remote url in four ways. 1. use file_get_contents to get the content as an example: $ htmlfile_get_contents ($ url); 2. use fopen to open the url and get the content as an example: $ fpfopen ($ url, r); $ htmlstream_get_meta_data ($ fp); 3. four methods for php to call remote URLs
1. use file_get_contents to get the content in get mode.
Example:

$html = file_get_contents($url); 

2. use fopen to open the url and get the content
Example:

$fp = fopen($url, 'r'); $html = stream_get_meta_data($fp); 

3. use the file_get_contents function to obtain the url in post mode.

 $data = array ('test' => 'hellword'); $data = http_build_query($data); $opts = array (  'http' => array (  'method' => 'POST',  'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .     "Content-Length: " . strlen($data) . "\r\n",  'content' => $data  ), ); $context = stream_context_create($opts); $html = file_get_contents($url, false, $context);

4. before using the curl Library, make sure that curl extension is enabled.

$ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents;
