The following is untested:
-----------------------------------------------------------
foreach( $myArray as $id => $entry )
{
if( ($pos = strpos( 'abcd' ) !== false && $pos === 0 )
{
$parts = explode( ' - ', $entry );
$myArray[$id] = $parts[0];
}
}
print_r( $myArray );
-----------------------------------------------------------
