$val="wqewq<div id='sdf hjhj'></div>qwewqewqewq"
替换成"wqewq<div id='sdf_test hjhj_test'></div>qwewqewqewq"
//其实也就是在class，id值后面加上一个字符串
／／我要替换的是文件里的。所以要从文件读取出来
／／我自己写了一个但是不行类似这样$fp=fopen("tpl_checkout_stacked.php","rb");
$content=fread($fp,filesize("tpl_checkout_stacked.php"));
$content=ereg_replace(" id='(.*)'"," id='\\1_test'",$content);
$content=ereg_replace(" class='(.*)'"," class='\\1_test'",$content);
echo($content);
fclose($fp);
$fp=fopen("test.php","a");
fwrite($content,$fp);
$content = file_get_contents($filepath);
替换
file_put_contents($filepath, $content);
{
$fp = file_get_contents($filename);
$new_fp = str_replace($search_contents, $replace_contents, $fp);
file_put_contents($filename, $new_fp);
}// +------ 用法
file_modify('sdf hjhj', 'sdf_test hjhj_test', 'test10.html');
能运行吧
如果只是为了满足页面显示效果，可以不用改动PHP代码，在页面中加入JS代码，使用document对象操作即可。
preg_replace("/id='([^\s]+)\s+([^']+)/","id='$1_test $2_test'",$content);
$html="wqewq<div id='sdf hjhj'></div>qwewqewqewq";
$html = preg_replace("/class='([^\s]+)\s+([^']+)/i","class='$1_test $2_test",$html);
$html = preg_replace("/id='([^\s]+)\s+([^']+)/i","id='$1_test $2_test",$html);
echo $html;?>
验证的时候要看网页源代码才知道,div被浏览器解释执行了。

里面的所有ID，CLASS的值都要在原来的基础上加上_test这样
如class="columnRight" 变成class="columnRight_test"
