operatore di confronto in variabile

[Virus_101]

Hai 2 soluzioni
1 eval
2 switch oppure if

mi spiego meglio

1 eval :

$controllo  = ">=" ;

$val1 = 10 ;
$val2 = 9 ;

$ctrl = $val1." ".$controllo." ".$val2 ;

if( eval($ctrl) )
  echo "Yeppa" ;
else
  echo "Mannaggia al cane" ; 

2switch

$controllo  = ">=" ;

$val1 = 10 ;
$val2 = 9 ;
$out = false ;
switch( $controllo )
{
       case "==" :  $out = $val1 == $val2 ; break;
       case ">=" :  $out = $val1 >= $val2 ; break;
       case ">" :  $out = $val1 >$val2 ; break;
       case "<=" :  $out = $val1 <= $val2 ; break;
       case "<" :  $out = $val1 < $val2 ; break;
}

if( $out )
echo "yeppa";
else
echo "Mannaggia al cane";
