reordering a string

[DragonHighLord]

If you have an array, you can shuffle() the array to reorder the contents of it. Is there soemthing similar to do this with just one string.For instance:
$string = "abcdefg";

do some shuffling code here

echo $string;
Instead of seeing: "abcdefg"...I should something like "cgafbde" instead. I thought about maybe tear the string apart with explode, put into array and then put back together. But I can only get explode to work with pulling out certain characters and the contents of the string will constantly change. Also, even if that was the way the go, I don't quite get the whole explode, implode functions, so not sure if I should be looking that way and if so, how do I do it? Thansk everybody.

$string = 'abcdefg';
for ($i = 0; $i < strlen ($string); $i++) {$array[] = substr ($string, $i, 1);}
shuffle ($array);
$string = implode ('', $array);
echo $string;

and if your looking for a certain order, look into the array_push and array_pop functions as well

Thanks, that works perfectly...I went to the manual and looked up each of the functions you used there so I would understrand what was going on and now it makes sense. It was kind of like what I was thinking, tear the string apart, put into an array, shuffle, and put back...I just wasn't sure exactly how to write it.

Thanks again
