Question

I have a PHP variable that holds similar data:

$var = "
Name: Tom
Age: 26
Location: London

Name: Mike
Age: 28
Location: New York

Name: Sunny
Age: 24
Location: Tokyo";

I’d like to extract only the locations, and store them in Array like:

Array
(
    [0] => London
    [1] => New York
    [2] => Tokyo
)

For now, with my simple experience with PHP I’m getting this done using “LOL, Don’t Laugh..“:

$location = array_merge(preg_replace('/^Location: /','',preg_grep('/^Location: /',explode("\n", $var))));

But I believe, there would be a way better process (maybe with preg_split) to achieve that faster, wiser and with maybe less system over-load.

Kindly, advise..
Thanks in advance.. 🙂

Answer 1

preg_match_all('/Location: (.+)/', $var, $m);
print_r($m[1]);

That works because the dot doesn’t match new line characters, by default.
