<?php $page = '<!-- WebAppleHeader --><div class="sheader"></div><!-- /WebAppleHeader --> 阿萨德发射点发射得分        <!-- WebAppleIndexBanner -->
            <img  src="/images/sinaapp/img/example1.png" class="sbanner" alt=" php 正则表达替换,为何不能替换解决思路 " >
        <!-- /WebAppleIndexBanner -->';




[b]//替换内容
$local_replace_area[0] = 'replace_area_1<hr>';   //这里替换不了?

$patterns[0] = "/^<!-- WebAppleHeader -->[\s\S]*<!-- \/WebAppleHeader -->$/i";//这里替换不了?[/b]

$page = preg_replace($patterns, $local_replace_area, $page);       

echo $page;
?>


Copy after login






------解决方案--------------------
$patterns[0] = "/^[\s\S]*$/i";//这里替换不了?[/b]

最后的$有问题,并不是字符串结束部分,去掉试试?
