PHP Functions file_get_contents High usage

This article describes the PHP file_get_contents advanced usage, share to everyone for your reference.

The specific analysis is as follows: first solve the file_get_contents timeout problem

After the time-out error, like JS in the settimeout like a try, the error more than 3 or 5 times after the confirmation that the server can not be connected and completely abandoned.

Here's a quick introduction to two workarounds:

One, increase the time limit of timeout note:

Set_time_limit only sets the time-out for your PHP program, not the time-out for the file_get_contents function to read the URL.

At first I thought set_time_limit could also affect File_get_contents, which was later tested to be ineffective.

The real modification file_get_contents delay can be used with the timeout parameter of the resource $context.

The PHP program code is as follows:

  <>< p=""><>
Fpassthru ($FP);

Second, several attempts

The PHP program code is as follows:

  
   
$cnt = 0;
    while ($cnt < 3 && ($str = @file_get_contents (' http ... ')) {===false) {
      $cnt + +;
}

The above method against timeout is OK.

Third, using file_get_contents to achieve post

as follows: PHP program code

  
   
echo Post (' http://www.scutephp.com ', $data);

Note the set_time_out of the document header or the entire document is timed out.
