Return substring in array with regex

Question

I have the following string, eg: 'Hello [owner], we could not contact by phone [phone], it is correct?'.

Regex would like to return in the form of array, all that is within []. Inside the bracket will only alpha characters.

Return:

$array = [
  0 => '[owner]',
  1 => '[phone]'
];

How should I proceed to have this return in php?

Answer 1

Try:

$text = 'Hello [owner], we could not contact by phone [phone], it is correct?';
preg_match_all("/\[[^\]]*\]/", $text, $matches);
$result = $matches[0];
print_r($result);

Output:

Array
(
    [0] => [owner]
    [1] => [phone]
)
