Parameter passing

[nesli]

I need help in passing parameters with special chars

I have in script1.php
$x= 'A & B';

<a href=\&quot;script2.php?x=$x\&quot;>$x</a>

but when I echo $x in script2.php I get only A
the other part (& B) is lost. Why ? How to pass
the right way ?

To do this, you need some function to change characters like the ampersand (&) into their hex equivalents for the query string.

Something like this:
function intoHex($char) {
return '%'.bin2hex($char);
}

$myString = 'a & b';
print preg_replace(&quot;/([^\w\d])/e&quot;,&quot;intoHex('&quot;.&quot;\\1&quot;.&quot;')&quot;,$myString);

Note that that last preg was formatted for a pre 4.04 version of PHP...Newer versions may require a slight change.

hope this helps,

Yes, you can do it with regex, and in some specific cases you might need that, but PHP comes with a built-in function to handle escaping query strings, and it works fine for every situation I've needed. See

http://www.php.net/urlencode.

Oh yeah.

It helped
I went for the obvious and urlencode() and urldecode()
worked fine.
Thanks
