How do I turn strings into arrays?

can I do it?

How do I turn a string into array where all the characters in the string to seprate values.

Something like this:

$string = "High";

to this:

$array = array('h','i','g', 'h');

Thanks,

From the manual...

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

A string is already an array.

$string = "High";

echo $string[0];
echo $string[1];
echo $string[2];
echo $string[3];

or

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

or

$new = array();

for ($i=0; $i<strlen($string); $i++)
{
$new[] = $string[$i];
}

Hope that also helps.

Square brackets for accessing single string characters is depreciated [us3.php.net]. Use curly brackets instead.

print($string[0]); //will work now, may not in future

print($string{0}); //"better"

That's cool! They must have changed to curly brackets because technically a string is not an array. That is, you can't use the array functions just on a string. So I like your second method dreamcatcher. I wonder which one would be faster?

I was looking for something else and found this.

$str = 'string';
$chars = str_split($str);
print_r($chars);

More then one way to skin a cat...

I felt the same way about file_put_contents(). It seemed so sad that file_get_contents() works in PHP4, but it's complement doesn't, so now I put a file_get_contents() in my standard library with a conditional function definition so it only gets defined if the function file_get_contents() doesn't exist.
