Problems with eregi_replace

[cerrajero69]

Hi, first of all, sorry about my english, the last time I spoke english ..... I don't remember it... 🙂

I have a problem using eregi_replace, because when I want to replace a word with "á, é,í, ó, ú or ñ" or some special chars....the function fail.

I have a function that read a file and return the equivalent string. I apply the eregi_replace function to this string with a word to replace... but if the word or the string have some special chars don't work....

But, in this code.... it works successfully..... :-s

<?php

$cadena="Esto es la esdrújula";
$contenido=eregi_replace("esdrújula","<a name='posicion'><font color='#FF0000'><strong></strong></font></a>",$cadena);
echo $contenido;

?>

Help me please.... :-)
