Sorry, I typed a hypen instead of an underscore:

 list($firstpart, $newvar) = explode('_', $var);

The explode() function returns an array. Each element of the array will contain the part of the string between the delimiter.

The list() function allows you to take an array and break it into individual variables. In this case, you will only use the $newvar variable, and can simply ignore the $firstpart variable.

with explode in newvar you have an array
$newvar[0] = 'number_'
$newvar[0] = 'XXXX'

excuseme:
$newvar[1] = 'XXXX'
if you have 3 parts, for example
number_123_456
with explode you obtain:
$newvar[0] = 'number_'
$newvar[1] = '123_'
$newvar[2] = '456'

Are you sure that $var is indeed a string containing 'number_xxxx'? Can you post the output of:

var_dump($var);

With explode, you obtain an array, that contains the original string splits by the character you choose
For example:
$original_string = 'This_is_a_test'
$parts = explode ('_', 'This_is_a_test');

So you now have that $parts is an array
$parts[0] = 'This'
$parts[1] = 'is'
$parts[2] = 'a'
$parts[3] = 'test'
