但是我们可以用正则进行替换:
复制代码 代码如下:
<?php
function dhtmlspecialchars($string) {
if(is_array($string)) {
foreach($string as $key => $val) {
$string[$key] = dhtmlspecialchars($val);
}
} else {
$string = preg_replace("/&((#(d{3,5}|x[a-fA-F0-9]{4})|[a-zA-Z][a-z0-9]{2,5});)/", "&\1",
str_replace(array("&", """, "<", ">"), array("&", """, "<", ">"), $string));
}
return $string;
}
?>
