Doc #66765 [NEW]: strtr key replacing order
From: pawel dot ulewicz at gmail dot com
Operating system: Windows 7
PHP version: 5.5.9
Package: Strings related
Bug Type: Documentation Problem
Bug description:strtr key replacing order
Description:
------------
It looks like strtr function replaces strings in the following order:
1) first occurences first,
2) longest keys first.
I don't think it's a bad thing, but it doesn't work as documented.
Here's the quation from the official docs:
"The longest keys will be tried first"
So, it's either a documentation problem or a bug.
Test script:
---------------
<?php
// expecting 'bcde' to be replaced first
echo strtr('abcdef', ['abc'=> '1', 'bcde'=>
'2']) . "\n";
// the following two are replaced as expected, just to give more info
echo strtr('abcdef', ['a'=> '2', 'abc'=>
'1']) . "\n";
echo strtr('abcdef', ['abcd'=> '2', 'abc'=>
'1']) . "\n";
Expected result:
----------------
a2f
1def
2ef
Actual result:
--------------
1def
1def
2ef
