Fall-through Switch Case with For Loop PHP -

please help.

for($i=0; $i<12; $i++ ){         switch($i) {             case 0:             case 1:             case 2:             case 3:             case 4:                 echo ("i less 5 <br>");                 break;             case 5:             case 6:             case 7:             case 8:             case 9:                 echo ("i less 10 <br>");                 break;             default:                 echo ("i 10 or more <br>");         }     } 

this example code got in java book , translated code above php.

the output of following code:

i less 5  less 5  less 5  less 5  less 5  less 10  less 10  less 10  less 10  less 10  10 or more  10 or more 

my question how come case 0 case 3 outputs "i less 5" though doesn't have following code , case 4 1 echo statement? i'm confused, can explain me. in advance.

that's how switch supposed operate. in order stop falling through next case have use break keyword. it's same in every language know, including javascript, php , python.

for reference, check out php manual.
