PHP function that translates, e.g., "æ" into "ae" and vice versa?

Question

是否有 PHP 函数可以将“Æ”等连字转换为“AE”，反之亦然？

Answer 1

You could use one of a few of PHP's functions, one being the preg_replace() function.

<?php

$replace='Æ';
$new=str_replace('Æ', 'AE', $replace); 

echo $new;

Will echo AE

---

Vice-versa would be:

<?php

$replace='AE';
$new=str_replace('AE', 'Æ', $replace); 

echo $new;

Will echo Æ

---

Using the str_replace() function, it can be used in sentences, such as:

echo str_replace("Æ","AE","Æ has been replaced from using: ") . "Æ";

Which will echo AE has been replaced from using: Æ

Answer 2

iconv with " //TRANSLIT " works very well:

$strWithoutLigatures = iconv("utf-8", "us-ascii//TRANSLIT", $strWithLigatures);
