php结合正则批量抓取网页中邮箱地址

<?php  $url='//www.VeVB.COm'; //要采集的网址   $content=file_get_contents($url);  //echo $content;  function getEmail($str) {  //$pattern = "/([a-z0-9]*[-_/.]?[a-z0-9]+)*@([a-z0-9]*[-_]?[a-z0-9]+)+[/.][a-z]{2,3}([/.][a-z]{2})?/i";  $pattern = "/([a-z0-9/-_/.]+@[a-z0-9]+/.[a-z0-9/-_/.]+)/";  preg_match_all($pattern,$str,$emailArr);   return $emailArr[0];  }  print_r( getEmail($content));  ?>

<?php $url='//www.VeVB.COm'; //当页已留邮箱$content=file_get_contents($url);             //获取页面内容function getEmail($str) {                 //匹配邮箱内容$pattern = "/([a-z0-9/-_/.]+@[a-z0-9]+/.[a-z0-9/-_/.]+)/"; preg_match_all($pattern,$str,$emailArr); return $emailArr[0]; } print_r( getEmail($content)); ?>
