foreach循环中的str_replace

Question

<?php 

$url = "http://localhost/news&lang=en&lang=sk&lang=sk&lang=sk&lang=en";

$langs = array ('sk', 'en');

foreach ($langs as $lang) {
    $search = '&lang='.$lang;    
    $new = str_replace($search, "", $url);
}

echo $new; // output: http://localhost/news

?>

Q: How to delete all parameters (&lang=en, &lang=sk) from string ?

Thank you in advance

Answer 1

What you are doing is creating a new variable $new each time so that won't do anything good with the $url. Try to assign the str_replace back to its original variable like:

$url = "http://localhost/news&lang=en&lang=sk&lang=sk&lang=sk&lang=en";

$langs = array ('sk', 'en');

foreach ($langs as $lang) {
    $search = '&lang='.$lang;    
    $url = str_replace($search, "", $url);
}

echo $url; // output: http://localhost/news
