string split

[jagguy]

Hi,

 

I am recieving  a POST variable with numbers seperated by underscores in this format eg

 

2_19  or 1_2_12 etc of variable length but usually no more than a few underscores between each number.

 

How can i extract the numbers from this string as I have looked at substr but this requires knowing the exact length of the numbers.

If i don't know the size and numbers before hand what can i do to get the numbers seperated by underscore on their own?

$nums=explode("_",$numbers);
print_r($nums);

Hi,

 

Tkanks for that answer.

 

how do you remove the last number and '_' from the same list?

I can do it a long way but is their  an easy way.

 

eg 1_19_65

 

to

 

1_19

<?php

$nums = explode("_",$numbers);
unset($nums[count($nums)-1]);
print_r($nums);

?>

 

 

Orio.

Or this way... Using array_pop()

 

<?php

$nums = explode("_",$numbers);
array_pop($nums);
print_r($nums);

?>

 

Orio.
