Solution to file_get_contents being blocked_PHP tutorial

In php, the file_get_contents function can directly collect the content of the remote server and then save it to a variable. The mediator usually disables some IO operation functions such as file_get_contents, fsockopen and so on, because they are afraid of being DDOS

In this case, we cannot change the server's inc.php, and can only write a set of IO ourselves to replace the above PHP function.

The code is as follows

代码如下	复制代码
$url = file_get_contents('http://www.bKjia.c0m/');

Copy code

代码如下	复制代码
//禁用file_get_contents的解决办法 $ch = curl_init(); $timeout = 10; // set to zero for no timeout curl_setopt ($ch, CURLOPT_URL,'http://www.hzhuti.com/'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $url = curl_exec($ch);

$url = file_get_contents('http://www.bKjia.c0m/');

We can use the following code instead

The code is as follows

代码如下	复制代码
function vita_get_url_content($url) {  if(function_exists('file_get_contents')) {  $file_contents = file_get_contents($url);  } else {  $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);  }  return $file_contents;  }  ?>

Copy code

//Solution to disabling file_get_contents $ch = curl_init();

$timeout = 10; // set to zero for no timeout

curl_setopt ($ch, CURLOPT_URL,'http://www.hzhuti.com/'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $url = curl_exec($ch); Curl is a tool that uses URL syntax to transfer files and data. It supports many protocols, such as HTTP, FTP, TELNET, etc. It will not be disabled by the server, so we can use it to simulate file_get_contents to open a URL. Use the function_exists function to determine whether PHP supports a function and you can easily write the following function

The code is as follows

Copy code

function vita_get_url_content($url) { if(function_exists('file_get_contents')) { $file_contents = file_get_contents($url); } else { $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); } return $file_contents; } ?> http://www.bkjia.com/PHPjc/632091.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/632091.htmlTechArticleIn php, the file_get_contents function can directly collect the content of the remote server and then save it to a variable.
