Accessing a $_GET variable whose value contains '&'

What is a good workaround for fields that have '&'? I have a site that is getting stuff via $_GET, but some of the fields are, for example: 'Pants & shorts'... When I put this in a URL it gets all messed up :) Any PHP fix for it? :)

F开发者_如何学Goor example:

http://localhost/clothes/?sex=both&order=newest&time=all&type=Pants%20&%20Shorts

Thank you!

Check the PHP manual for urlencode() http://nl.php.net/manual/en/function.urlencode.php

http://www.php.net/manual/en/function.urlencode.php

or:

http://www.php.net/manual/en/function.http-build-query.php

when writing the url:

http://localhost/clothes/<? echo urlencode('pants & shorts'); ?>/

PHP seems to de-encode names when they are url-encoded, so you could use:

[pants & shorts] == [pants%20%26%20shorts]

When building URI query, either use http_build_query or rawurlencode:

$query = array('sex'=>'both', 'order'=>'newest', 'time'=>'all', 'type'=>'Pants & Shorts');
$url = 'http://localhost/clothes/?'.http_build_query($query);

$url = 'http://localhost/clothes/?sex=both&order=newest&time=all&type='.rawurlencode('Pants & Shorts');

One workaround I have used (even though it might not be the best solution) is to change the & with text and after you retrieve it via $_GET you can change it back.

For example you would change the & for "andsign" before sending it:

 $your_var_without_and = str_replace("&", "andsign", $your_var);

And change it back after retrieving it:

 $your_var_without_and = $_GET['your_var_without_and'];

 $your_var = str_replace("andsign", "&", $your_var_without_and);
