PHP rewrites the file_get_contents function example based on curl

Dec 23, 2016 pm 03:34 PM

The example in this article describes how PHP rewrites the file_get_contents function based on curl. Share it with everyone for your reference, the details are as follows:

file_get_contents will prompt Connection refused when the connection cannot be reached, which sometimes causes inconvenience; in addition, the performance of curl is higher than file_get_contents, so use curl to rewrite file_get_contents

function _file_get_contents($s) {
  $ret = "";
  $ch = curl_init($s);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 0);
  $buffer = curl_exec($ch);
  curl_close($ch);
  if ($buffer === false || empty($buffer)) {
    $ret = "";
  } else {
    $ret = $buffer;
  }
  return $ret;
}
Copy after login

Hope What this article describes will be helpful to everyone in PHP programming.
