I needed a function to rotate the results of a preg_match_all query, and made this. Not sure if it
exists.
<?php
function turn_array($m)
{
for ($z = 0;$z < count($m);$z++)
{
for ($x = 0;$x < count($m[$z]);$x++)
{
$rt[$x][$z] = $m[$z][$x];
}
}
return $rt;
}
?>
Example - Take results of some preg_match_all query:
Array
(
[0] => Array
(
[1] => Banff
[2] => Canmore
[3] => Invermere
)
[1] => Array
(
[1] => AB
[2] => AB
[3] => BC
)
[2] => Array
(
[1] => 51.1746254
[2] => 51.0938416
[3] => 50.5065193
)
[3] => Array
(
[1] => -115.5719757
[2] => -115.3517761
[3] => -116.0321884
)
[4] => Array
(
[1] => T1L 1B3
[2] => T1W 1N2
[3] => V0B 2G0
)
)
Rotate it 90 degrees to group results as records:
Array
(
[0] => Array
(
[1] => Banff
[2] => AB
[3] => 51.1746254
[4] => -115.5719757
[5] => T1L 1B3
)
[1] => Array
(
[1] => Canmore
[2] => AB
[3] => 51.0938416
[4] => -115.3517761
[5] => T1W 1N2
)
[2] => Array
(
[1] => Invermere
[2] => BC
[3] => 50.5065193
[4] => -116.0321884
[5] => V0B 2G0
)
)
