Question

How can I transform

Array1
(
    [0] => Some Text
    [1] => Some Other Text (+£14.20)
    [2] => Text Text (+£26.88)
    [3] => Another One (+£68.04)
)

Into associative array like the one below:

Array2
(
    [Some Text] => 0 //0 since there is no (+£val) part
    [Some Other Text] => 14.20
    [Text Text] => Text Text 26.88
    [Another One] => 68.04
)

Answer 1

$newArray = array();
foreach( $oldArray as $str ) {
    if( preg_match( '/^(.+)\s\(\+£([\d\.]+)\)$/', $str, $matches ) ) {
        $newArray[ $matches[1] ] = (double)$matches[2];
    } else {
        $newArray[ $str ] = 0;
    }
}
