Question

how to remove a & Symbol from a url address use php regular? for example: http://www.google.com/search?hl=en&q=php left the & and get : http://www.google.com/search?hl=enq=php Thanks

Answer 1

$url = 'http://www.google.com/search?hl=en&q=php';
$url = str_replace('&', '', $url);

Answer 2

I'm not sure I really understand the question. It sounds like you just want to remove & characters. That can be easily done:

$url = str_replace('&', '', $url);

Answer 3

You can remove it easily enough with str_replace. Why you would want to do this, however, is another matter entirely.

Are you trying to insert a URL into a page with PHP and getting validation errors due to the & symbol? In that case urlencode() might be what you really need.
