splitting PHP strings

Hi,
I've recenty transformed some XML with XSL and PHP. as shown in the code below.
Now i need to split the $html string (which is the resultant HTML output of the XML file)
into single characters instead of printing it to screen. Inhave tried the ususal PHP methods for splitting a string, nothing seems to work. I have also tried putting the string into an array. Again, nothing works. Could anyone please help me?

<?php

// Create an XSLT processor
$xsltproc = xslt_create();

// Perform the transformation
$html = xslt_process($xsltproc, 'results1.xml', 'results1.xsl');

// Detect errors
if (!$html) die('XSLT processing error: '.xslt_error($xsltproc));

// Destroy the XSLT processor
xslt_free($xsltproc);
//print out the HTML
echo $html;

?>

Thanks

Jo

Did you try splitting on an empty string? Failing that, you could iterate over the string using strlen() as your counter and strpos() to get the current character.

Why the heck do you want it in single characters?

Whatever, the following function returns an array containing the characters of the inputted string as entries. Hope it helps.

PHP Code:


		
			
function str_to_chars($input_string)

{

    $output_array = array();



    # first element of output array is amount of characters

    array_push($output_array, strlen($input_string));



    # other elements ($output_array[1] upto and including $output_array[$output_array[0]])

    # are the characters of the string

    for($i = 0; $i < strlen($input_string); $i++)

        array_push($output_array, substr($input_string, $i, 1));



    return $output_array;

}

Hope it's of use.
