How to convert string to number in PHP?

Could any one tell me how to convert string data to number?

For example:

$Str = "212315"; // convert to 212315

Answer 1

You cast it to an integer.

(int) $Str;

http://php.net/manual/en/language.types.type-juggling.php#language.types.typecasting

To explicitly convert a value to integer, use either the (int) or (integer) casts. However, in most cases the cast is not needed, since a value will be automatically converted if an operator, function or control structure requires an integer argument. A value can also be converted to integer with the intval() function.

Answer 2

you can do several things

$str = "212315";

$int = intval($str);

$int2 = (int) $str;

$int3 = (integer) $str;
