displaying a string backwards...

DXL

ive been looking a little at ASP, and i saw something that reverses what you input.

i wanted to see if this could be done, but ive been racking my brain, and had no luck

is there a way to reverse a string in PHP?

Don't rack brain, just read manual.

http://www.php.net/strings

There is a rich set of string-handling functions, including strrev().

strrev();
check the manual.

DXL

ohh, cool

i almost never read the manuals, and do things the prehistoric way: experiment

thanx

DeadFly

the php manual is very good.
you should always check it out before asking questions, because 90% of the time the manual will point you in the right direction.

ok...

even though i like learning things myself, because i remember it in an easier fashion

new question:

how can you do a 'hack' affect?

Example: HeLlO tHiS iS dXl

can you do that more easily than typing it?
#note: i dont see it on http://www.php.net/strings

look up str_replace (on that same page)

A simplistic function for that might be:

function hackStr($str) {
	$str = strtolower($str);
	$len = strlen($str);
	for ($i = 0; $i < $len; $i += 2) {
		$str{$i} = strtoupper($str{$i});
	}
	return $str;
}

not sure how to optimise it, though.

Merve

function hackStr($str) {
    $str = strtolower($str);
    $len = strlen($str);
    $i=0;
    while ($i<$len) {
        $str{$i} = strtoupper($str{$i});
        $i=$i+rand(1,4);
    }
    return $str;
}

That might work slightly better...
