Splitting a string in PHP

Gordon

I am slowly (very slowly..) learning PHP and there is something I'd like to be able to do which involves splitting a string of numbers.

I have an outputted number eg: 146
I would like to turn this into: <img src="1.jpg" /><img src="4.jpg" /><img src="6.jpg" />

I've looked into explode and split functions but all of them seem to need a delimiter in the string.

Anybody any ideas as to what php function I need to Google?

split() should still work without a delimter. OK, well not without one, but with an empty string, i.e.

split("", myString);

You should also be able to iterate through the string and get each character in turn;

for($i = 0; $i < strlen(myString); $i++) {
$char = substr(myString, $i, 1);
echo '<img src="$char.jpg" />';
}

<?php


$string = "12345";

$chars = preg_split('//', $string, -1, PREG_SPLIT_NO_EMPTY);

foreach($chars as $image){
$list .= "<img src=\"./$image.jpg\">";
}
echo $list;

?>

You guys rock, thank you so much

Now I'm going to have to dissect both of your codes and try to understand why they both work and how they both work!

Cheers.
