Question

I am trying to change a js program to php. there is a replace function like $t = t.replace(/B/g, "b");

if i change this to php as $t = str_ireplace(/B/g, "b",$t);

这表明了“不投机”的错误。

Answer 1

首先,Javagust s replace功能最接近preg_replace。

第二,请> “str_ireplace” ,由于你重新试图将B变成b,因此,该软件对案件不敏感,正是使用错误功能。

You can do $t = str_replace( B , b , $t); (simpler) or $t = preg_replace( /B/ , b , $t); (can handle more complex situations than what you re doing).

Answer 2

要求Javascript取而代之的是使用固定表述作为搜索标准。

PHP Equivalent is preg_replace
