[SOLVED] split string into array by string position - not delimiter?

[Anti-Moronic]

What I want to do is split a string by the string position, like so:

 

string position: 4

 

$str = "123|321|123";

 

what I want to output is 2 strings into an array:

 

array('123|', '321|123');

 

Any help is greatly appreciated. thanks.

try explode

 

edit:

Darn I mean substr

you could use explode and add the last two entries together

[Anti-Moronic]

Can't use explode on this. That would remove the | and split the string into 3:

 

array('123', '321', '123');

 

Thanks anyway. Maybe there is a way to do it with explode, but I can't reply on a character, I need to rely on an actual position within the array.

substr() will do what you want

I was hoping substr wasn't the only way. Thanks.

It isn't you can also use a regular expression with one of the preg_ functions

darn beer

$pos = 4;
$str = "123|321|123";
$str = preg_split('~(.{'.$pos.'})~s',$str,2,PREG_SPLIT_DELIM_CAPTURE);
echo "<pre>";
print_r($str);

 

output:

Array
(
    [0] => 
    [1] => 123|
    [2] => 321|123
)

Wow, thank you very much CV - very much appreciated. Now I can use preg_split! thanks again.
