This is what i had before in my linear code

function merchantSort($a,$b){
    return ....// stuf         


        

Answer 1

You need to pass $this e.g.: usort( $myArray, array( $this, 'mySort' ) );

Full example:

class SimpleClass
{                       
    function getArray( $a ) {       
        usort( $a, array( $this, 'nameSort' ) ); // pass $this for scope
        return $a;
    }                 

    private function nameSort( $a, $b )
    {
        return strcmp( $a, $b );
    }              

}

$a = ['c','a','b']; 
$sc = new SimpleClass();
print_r( $sc->getArray( $a ) );
