Count from a specific array in explode

Question

Is it possible to count from a specific array in explode?

Example:

<?php
$number='This is the number of,5,6,7,8,9';
$collect=explode(",",$number);
print_r($collect);
?>

Output will be:

Array ( [0] => This is the number of [1] => 5 [2] => 6 [3] => 7 [4] => 8 [5] => 9 )

But I need to ignore the first array. Meaning, that I want to count only 5,6,7,8,9 and ignore "This is the number of".

unset($collect[0]);

See http://php.net/manual/en/function.unset.php

This is bad because array elements will be counted from 1, not from 0. It's unexpected behaviour in most cases. – Pavel Strakhov Nov 25 '12 at 09:34

You can use array_shift to remove first element of the array.

You wrote "I want to ignore first array" but you obviously meant "array element". Note that "array" is the whole output of explode function.

It is possible.

Directly you can remove the first element of the array:

$number='This is the number of,5,6,7,8,9';
$collect=explode(",",$number);
unset($collect[0]);
print_r($collect);

But briefly, you should use regular expressions so you match only the numbers:

preg_match_all('/,(\d+)/, explode(",",$number), $collect);

see http://php.net/manual/en/function.preg-match-all.php

just use the below code instead of yours... here I am just adding a new line... the 4th one...

<?php
$number='This is the number of,5,6,7,8,9';
$collect=explode(",",$number);
array_shift($collect); // remove the first index from the array
print_r($collect);
?>

Output:

 Array ( [0] => 5 [1] => 6 [2] => 7 [3] => 8 [4] => 9 )
