say i have a string like

$string = "123abc";

i want to go and use each letter in the string seperately so i would have it in an array.
i tried doing it with explode -

$array = explode("", $string);

but that doesn't work. is there a way with foreach?
any suggestions?

Tom

This is just a theory

for( $i=0; $i < strlen( $str ); $i++ )
{
  $arr[] = $str[$i];
}
echo prinr_r( $arr )

I think that should do the trick

both of those didn't work.
but... if you have a string-

$string = "123456";

then

echo $string{0};

will echo 1

echo $string{2};

will echo 3 and so on.

$arr=array();
for( $i=0; $i < strlen( $str ); $i++ )
{
  $arr[$i] = $str[$i];
}
echo prinr_r( $arr )

Try this. It should work

My apolagies, im getting things muddled me finks. This works (i tried it this time)

$string = "123abc";
$count = strlen( $string );
$i = 0;
$array = array();
while($i < $count+1)
{
		 $array[$i] = $string{$i++};
}

print_r ( $array );

Edit: futingkiller got there first lol

[Matthew.]

You just forgot the $arr = array(); Cliff.

[coolaid]

i know topics solved, but shouldnt the
$arr[$i] = $str[$i];

be

$arr[$i] = $str{$i};

???

and the the $i < strlen($str) be $i <= strlen($str) ???

no, it should be just "<" because the length of a string in this case " $string = "123abc";" is=6, and $i starts from 0 to 5-->6 elements.
$arr[$i] = $str{$i}; is correct, it's my mistake.
cliff, i used your script and corected it, sorry for copying (but it's the best way to use, and i usualy use it just like that).
.Matt it wasn't just the $arr=array(); It's " $arr[$i] = $str[$i];" also
.Matt are you positive that "while($i < $count+1)" can't be replaced with: "while($i < $count)"??

[Ruben K]

Well you corrected it wrong 8-)

You don't have to define an array, it becomes one automatically.
You can just do $arr[], as it will move to the next index.

I would've done it this way.

$string = "123abc";
$stop = len($string);
$count = 0;
While ($count <= $stop){
echo $string[$count];
$count = $count + 1;
}

[Matthew.]

lmao, Futingkiller yes, yes i dont know why i put +1.

[Futingkiller]

Cliff, then it's diferent from all the other programing languages that i use
i am not that good of a php programer. i am better in javascipt
