We are talking about Multi Byte ( e.g. UTF-8) strings here, so preg_split will fail for the following string:
'Weiße Rosen sind nicht grün!'
And because I didn't find a regex to simulate a str_split I optimized the first solution from adjwilli a bit:
<?php
$string = 'Weiße Rosen sind nicht grün!'
$stop = mb_strlen( $string);
$result = array();
for( $idx = 0; $idx < $stop; $idx++)
{
$result[] = mb_substr( $string, $idx, 1);
}
?>
Here is an example with adjwilli's function:
<?php
mb_internal_encoding( 'UTF-8');
mb_regex_encoding( 'UTF-8');
function mbStringToArray
( $string
)
{
$stop = mb_strlen( $string);
$result = array();
for( $idx = 0; $idx < $stop; $idx++)
{
$result[] = mb_substr( $string, $idx, 1);
}
return $result;
}
echo '<pre>', PHP_EOL,
print_r( mbStringToArray( 'Weiße Rosen sind nicht grün!', true)), PHP_EOL,
'</pre>';
?>
Let me know [by personal email], if someone found a regex to simulate a str_split with mb_split.
