php多个字符串替换成同一个的解决方法

复制代码 代码如下:

<?php
$name = 'Today 3? , very/ cold';
$name = strtolower($name);
//$name = preg_replace('/[^a-z0-9/s]/','',$name);
$name = preg_replace('/[/./s+/?,//"]/','_',$name); //change spaces
echo $name;
?>

复制代码 代码如下:

$name = preg_replace('/[/./s+/?,//"]/','_',$name); //change spaces
