Comment by j on "How I can extract all the numbers in an array from a string in PHP?" | Hashnode

stuff ;)

define extract? do you need to remove all numbers? or get all numbers?

one time I would use preg_match regex101.com/r/QZlV0L/1 the other time preg_replace.

but it heavily depends on the string structure maybe preg_match is just the hardcore variant ;)

j, I need to get all the numbers only and hold it in a variable.

stuff ;)

Ankur Singh and how does the string look like? are the numbers integers? :)

j string would be like a4dgf5456.

stuff ;)

Ankur Singh so preg_match it is ;D

and you need them grouped? like 4 and 5456 or you need every number on it's own? grouped:

$match = [];

preg_match_all('/(\d+)/m', 'a4dgf5456', $match);
var_dump($match);

separate:

$match = [];

preg_match_all('/(\d)/m', 'a4dgf5456', $match);
var_dump($match);
