Can anyone help me with a way to determine of two or more variables have the same value?  For instance,

$a1 = 1000 $a2 = 2000 $a3 = 2000 $a4 = 4000 $a5 = 5000 I want check these five variables and determine whether, as in this case, two or more of the variables have the same value. Any suggestions how I can do this?

<?php $a1 = 1000; $a2 = 2000; $a3 = 2000; $a4 = 4000; $a5 = 5000; $hits = array(); for( $i = 0; $i < 5; $i++ )

Should be:

    for( $i = 1; $i <= 5; $i++ )

{

    $hits[${'a'.$i}][] = 'a'.$i;

} foreach( $hits as $value => $vars ) {

    if( count( $vars ) > 1 )
    {
        echo 'Value: '.$value."\n";
        print_r( $vars );
    }

} ?>

Cheers, Rob.
