PHP Function Kilomega echo result

Question

function kilomega( $val ) {
if( $val < 1000 ) return $val;
$val = (int)($val/1000);
if( $val < 1000 ) return "${val}k";
$val = (int)($val/1000);
return "${val}m";
}

I want to set that function into my result data in table :

echo "<td class='td'>kilomega($sum_qty9)</td>";

But facing problem, the result of the echo to be :

kilomega(5000) should be 5k

Any advice ?

Answer 1

Function calls are not interpolated in a string so

echo "<td class='td'>kilomega($sum_qty9)</td>";

should change to

echo "<td class='td'>",kilomega($sum_qty9),"</td>";
