[RESOLVED] Split a string help

kbc1

I have a 4 random character string which I is passed to me via an external website and I store it in my database. What I want to do is to split the string into an array as such:

// This is obtained from the external website
$string = "1234";

// this is what I want to do with it
$myarray[0] = "1";
$myarray[1] = "2";
$myarray[2] = "3";
$myarray[3] = "4";

PHP 5 allows me to do this seamlessly with the following:

str_split($string);

But the hosts are running PHP 4 and this function is not supported.

Can anyone suggest an alternative method for me to achieve this?

Many Thanks

This is the fix:

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

Depending upon the application, you might not even need to do this. You can access each character in a string individually using brackets (as if it were an array):

$string = '1234';
for($i=0,$max=strlen($string); $i<$max; $i++) {
    echo 'Character #' . $i . ' = ' . $string[$i] . "\n";
} // outputs each character of the string individually
