php - Why is this code an infinite loop? -


before completing code, tested mistake , realized not stop:

$var = "any";  ($i=1; $i < 2; $i++){      $var.$i = "any";  }

why produce infinite loop? , why doesn't php produce error?

i did simple test :

echo $i;  $var.$i = "any"; var_dump($var);

result :

1string(3) "any" anzstring(3) "any"

so $i transformed "anz" , doesn't pass validation out of loop.

$var.$i = "any"; not correct, don't know trying do, if want fill , array should more :

$var = array(); ($i=1; $i < 2; $i++){   $var[] = "any"; }

if want change string letter letter :

$var = "any";     ($i=1; $i < 2; $i++){       $var[$i] = "a"; // asign new letter string @ $i position     }
