transform alpha to numeric "23" to 23

[kafkapower]

Hi !

This must be a very easy feature, but I'm a fresh starter in PHP, so I need this very bad !

How can I transform the string "23" in the number 23 ?

in C I have atoi, but in PHP, I don't have that function !

Thanks!

PHP has automatic type juggling, so often you don't even need to worry about type conversion, but if you want to explicitly change a variable type, you can use settype() --

http://www.php.net/manual/en/function.settype.php,

or you can use type casting -- Read further down on this page:

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

By the way, the PHP.net site is the best-organized developer reference I have seen yet. One neat feature they have is any string you enter after

http://www.php.net,

such as '

http://www.php.net/settype',

automatically either forwards you to the appropriate section in the manual, or runs a sitewide search for that term. Enjoy!
