PHP中TRIM的不同行为

Question

I have a piece of code, from this i want to remove some words from string but the trim() function is not showing proper output.

The code is below

<?php
$mystring = '/word-quotes-hope';
$findme   = '/word-quotes-';
echo $str = trim($mystring, $findme);
?>

and its output is hop , but it should be hope

Its working example http://codepad.viper-7.com/FxLZkp

Anybody knows why this is happening.

Answer 1

因为trim使用第二个字符串而不是整个字符串，而是单独的字符，并且在您的情况下，其中包含e ，并且字符串以e结尾，所以它消失了。

Answer 2

Try to use it with "ltrim"

echo $str = ltrim($mystring, $findme);

it will trims your string on "left"
