php函数strpos和substr在localhost和服务器中的不同结果

Question

suppose we have strings like "adjkadahsdjashd##kjhkhkjhkjhs" . and I want to cut them to for example adjkadahsdjashd and kjhkhkjhkjhs

so I wrote this on my computer :

<?php
$s="508462170##dfsfgdfggf";
echo substr($s,strpos($s,"#")+2)."</br>";
echo substr($s,0,strpos($s,"#"));
?>

and the result is okay , but when I upload this to server , it returns me nothing .

server php version is 5.2.17

:(

Answer 1

尝试回显strpos（）的结果以缩小问题范围。

Answer 2

An shorter way for your problem would be:

echo implode('<br/>', explode('##', $s));

did this work on booth platforms.

Also </br> is not valid HTML.
