Personal notes
Short for regular expression, a regex is a string of text that lets you create patterns that help match, locate, and manage text.
$array = array('Michael','Marian','Martina');
$matching_letters = 'ri';
$array = preg_grep("/{$matching_letters}/i", $array);$list = Array
(
[0] => Array
(
[lat] => '43.65529'
[lng] => '-79.38397'
[name] => 'Name'
)
[1] => Array
(
[lat] => '43.65328'

)
[2] => Array
(
[lat] => '43.65516'
[lng] => '-79.38892'

)Sort with latitude going smallest to largest with longitude also going smallest to largest after
array_multisort(
array_column($list, 'lat'), SORT_ASC,
array_column($list, 'lng'), SORT_ASC,
$row
);Array now looks like this
