Regular expression, help needed

[tommy082]

Hello, I am quite new in php and I have just started using regular expressions. Could anyone help me with this expression? I don't know why it is not working.

$string = My name is [[Tom]] and I live in [[Germany|Czech republic]];
$pattern = /\[\[(.*)[^(\]\])]\|/U

$string = preg_replace("$pattern", "", $string);
$string = preg_replace("/\]/", "", $string);

echo $string;

I would expect the result to be:
"My name is Tom and I live in Czech republic"
but what I get is "My name is Czech republic".
The whole part between the first [[ and the sign | is replaced..

I have been fighting with this for hours and didn't find a solution


Thanks for any help

i didn't test this but you can try:

PHP Code:

$string = My name is [[Tom]] and I live in [[Germany|Czech republic]];
$pattern1 = "/\[\[[^|]+|/"; // this will replace [[Germany|
$pattern2 = "/[\]\[]/"; // this will replace [ and ]

$string = preg_replace($pattern1, "", $string);
$string = preg_replace($pattern2, "", $string);

echo $string; 


best regards

PHP Code:

<?php

$string = 'My name is [[Tom]] and I live in [[Germany|Czech republic]]';
$pattern1 = "/(\[\[)[a-zA-Z]*\|/";
$pattern2 = "/[(\[\[)(\]\])]?/";
$string = preg_replace($pattern1, "", $string);
$string = preg_replace($pattern2, "", $string);


echo $string;
?>

outputs

My name is Tom and I live in Czech republic
