Well, maybe Ben Kenobi can help me as well, if he's any good with PHP?

I am trying to do something I have achieved in Flash but not in PHP.

Basically it is breaking a long, delimitered string into an array.

I broke the string into a three dimensional array in flash using the code below:


This nis the Flash::::::
__________________________________________________ ________________
tmpMenu = loadedMenu.split("^");
// EXAMPLE of what tmpMenu looks like after this:
//mainMenu="|1|,nav,a,|2|,nav,a1,|3|,txt,a11,|3|,txt ,a12,|2|,nav,a2,|3|,txt,a21";
for(a=3; a<tmpMenu.length; a++) {
// split lvl 1
tmpArr = tmpMenu[a].split(",");
if (tmpArr[1] != "nav") {
tmpMenu[a] = tmpMenu[a].split(",");
} else {
tmpMenu[a] = tmpMenu[a].split(",|2|");
tmpArr = tmpMenu[a][0].split(",");
tmpMenu[a].splice(0, 1, tmpArr[0], tmpArr[1], tmpArr[2]);
// split lvl 2
for (b=3; b<tmpMenu[a].length; b++) {
tmpArr = tmpMenu[a][b].split(",");
if (tmpArr[1] != "nav") {
tmpMenu[a][b] = tmpMenu[a][b].split(",");
if (tmpMenu[a][b][0] == "") {
tmpMenu[a][b][0] = "|2|";
}
} else {
tmpMenu[a][b] = tmpMenu[a][b].split(",|3|");
tmpArr = tmpMenu[a][b][0].split(",");
if (tmpArr[0] == "") {
tmpArr[0] = "|2|";
}
tmpMenu[a][b].splice(0, 1, tmpArr[0], tmpArr[1], tmpArr[2]);
// split lvl 3
for (c=3; c<tmpMenu[a][b].length; c++) {
tmpMenu[a][b][c] = tmpMenu[a][b][c].split(",");
if (tmpMenu[a][b][c][0] == "") {
tmpMenu[a][b][c][0] = "|3|";
}
}
}
}
}
}_________________________________________________ _________________

I was wondering how I could do it in PHP?

It's ultimately to create a dropdown menu in PHP with three levels.

Any clues would be fantastic as I don't know where to start?

Hi,

here is code that converts a structure like yours into a multi-level array:

<?
$navtree = array();
$navptr[0] = &$navtree;
$currlev = 0;
$temp = array();
$input = split(",", "|1|,nav,a,|2|,nav,a1,|3|,txt,a11,|3|,txt,a12,|2|,nav,a2,|3|,txt,a21")
for($n = 0 ; $n < count($input) ; $n +=3)
{       $type = $input[$n+1];
        $label = $input[$n+2];
        if(!ereg('\|([0-9])\|', $input[$n], $matched))
                die("problem near $n");
        $level = $matched[1];
        if($level > $currlev+1)
                die("preobelm ner $n");
        if($type == "txt")
                $navptr[$level-1][] = array(type => $type, label => $label);
        else
        {       //$temp["curr$n"] = array();
                $nm = "curr$n";
                $$nm = array();
                $navptr[$level-1][] = array(type => $type, label => $label, sub => &$$nm);
                $navptr[$level] = &$$nm;
                $currlev = $level;
        }
}
var_dump($navtree);
?>

Thanks heaps for that, I really appreciate you taking the time.

I'll look into it and see what I can come up with.
