convert string into integer

[robert_gsfame]

how can i convert string type into integer like when using parseInt in javascript...however i use (int)$string but not working

 

i have this

$string1="10";

$string2="5";

 

and i wish to add both string ....using (int) still treat $string1 and $string2 as string so i get 105 as a result instead of 15

If you want to get 105 then you want to treat them as strings and concatenate them.

 

$string1="10";
$string2="5";
echo $string1 . $string2; // 105

i want to get 15 not 105

Oh, sorry, your post was confusing. In that case you can add them normally as PHP will automatically convert them to integers for you when performing the arithmetic.

 

$string1="10";
$string2="5";
echo $string1 + $string2; // 15

oops sorry.... i made a mistake...i can add those string directly n no need to change the type  :P
