string to array

[iversonm]

OK so here is what I want to do. I have a bunch of strings stored in a table. The strings are like this grandparent.parent.child. some are just parent.child

What I want to do is Select all and then put them into an array.

 

soooo x.y.z would become $Var['x']['y']['z']

and a.b would become $Var['a']['b']

 

It has to be dynamic because some strings are just 2 levels, and it goes all the way up to 6 levels. I have different plans for setting the variably to something but I can handle that.

 

Any ideas?

<?php
$the_string = 'HELLO WORLD';
$the_string_length = strlen($the_string);
${'tmp_array_'.($the_string_length-1)}[$the_string[$the_string_length-1]] = true; // whatever you want it to be
for($i=$the_string_length-2; $i>=0; $i--){
if($i==0){
	$the_array[$the_string[$i]] = ${'tmp_array_'.($i+1)};
}else{
	${'tmp_array_'.$i}[$the_string[$i]] = ${'tmp_array_'.($i+1)};
}
}
print_r($the_array);
?>

Is this anywhere close?

Yeah that is very close. It just needs to know sort by where the periods are vs characters. some strings are essentials.admin.all where as some are hc.chat.all so the string length varies. they need to be broken up based on the periods because that is the breaking point for the different levels.

$string = "lemonade.is.awesome";
list($grandparent, $parent, $child) = explode('.',$string);

// grandparent = lemonade
// parent = is
// child = awesome

oh, right, didn't see that to be honest. o.o'

 

EDIT:

Fixed!

 

<?php
$the_string = 'HELLO.WORLD';
$the_value = true; // whatever you want it to be
$strings = explode('.', $the_string);
$strings_count = count($strings);
if($strings_count==1){
$the_array[$the_string] = $the_value;
}else{
${'tmp_array_'.($strings_count-1)}[$strings[$strings_count-1]] = $the_value; // whatever you want it to be
for($i=$strings_count-2; $i>=0; $i--){
	${'tmp_array_'.$i}[$strings[$i]] = ${'tmp_array_'.($i+1)};
}
$the_array[$strings[$i+1]] = ${'tmp_array_'.($i+2)};
}
print_r($the_array);
?>

BOOM. Exactly what I was looking for. I just had to add to $the_string on line 3(so it would use the right column for the mysql data)

it works exactly as I wanted. I will let you know if I have any thing else that comes up. Thank you for your help

<?php
function string_to_array($the_string, $the_value){
$strings = explode('.', $the_string);
$strings_count = count($strings);
$the_array[$strings[$strings_count-1]] = $the_value;
for($i=$strings_count-2; $i>=0; $i--){
	$tmp_array = $the_array;
	unset($the_array);
	$the_array[$strings[$i]] = $tmp_array;
}
return $the_array;
}
print_r(string_to_array('HELLO.WORLD', true));
?>

I rewrote it again, and this time as a function. This script is not as memory hungry either, and follows far better programming practices!
