preg_split first item in array is blank

[pdug175]

Hi, could someone please explain to my why using the code below generates a blank item in $array[0] please. The 'x' from xbox360 is in $array[1]?

 

Thank you.

 

 

$str="xbox360"'

 

$array= preg_split('//', $str, -1);

 

echo $array[0];

try this

$str="xbox360"'
$array= preg_split('//', $str, -1);
print_r($array);

Hi fert, thanks for the reply. I've not posted all my code because I'm doing some further manipulation with the string. I'm particularly interested why the first item isn't being assigned to $array[0], is there something stupid I'm doing with that code?

i have a feeling that's just how the code works - given that it "splits" on a regex, it will likely return the portion both before and after the match; that includes before the first position and after, which results in the empty first return.  try using:

 

<?php
$array= preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
?>

 

this will tell it to not bother returning any empty matches.

ahh, thank you.

 

I was just curious more than anything, your taught that '(0) is the first item in an array - seemed strange that it was blank
