本文实例讲述了php判断访问IP的方法。分享给大家供大家参考。具体如下:
<?php function getIP() { if (! empty ( $_SERVER ["HTTP_CLIENT_IP"] )) { $cip = $_SERVER ["HTTP_CLIENT_IP"]; } else if (! empty ( $_SERVER ["HTTP_X_FORWARDED_FOR"] )) { $cip = $_SERVER ["HTTP_X_FORWARDED_FOR"]; } else if (! empty ( $_SERVER ["REMOTE_ADDR"] )) { $cip = $_SERVER ["REMOTE_ADDR"]; } else { $cip = ''; } preg_match ( "/[\d\.]{7,15}/", $cip, $cips ); $cip = isset ( $cips [0] ) ? $cips [0] : 'unknown'; unset ( $cips ); return $cip; } ?>
希望本文所述对大家的php程序设计有所帮助。
