This mistake look like a paradox, but that's what I see:
Example 1:
$str = 'hypertext language programming';
$chars = preg_split('/ /', $str, -1, PREG_SPLIT_OFFSET_CAPTURE);
foreach($chars as $k=>$v){
$chars2[] = $chars[$k][0];
}
print_r($chars2);
Example 2:
$str = 'hypertext language programming';
$chars = preg_split('/ /', $str);
print_r($chars);
First example works faster then second. Why so?
