to an integer value in php??

If it's an actual integer value, PHP will automagically convert it to an integer. You could check if it is a digit or not by using if (ctype_digit($value))

im confused to your explanation sorry,, im entering it into my database which has a attribute of type integer,, but jus need 2 make sure i can enter integer values from the input box which is of course type text so need somethin to convert say my variable $x which is string to integer..... could anyone use the variable $x in their code to make it easier to understand plz thnx

you can use intval() to get the integer value, or is_numeric to check if it is.

[printf]

Read the manual, it's self explained, PHP by default is a loosed type language, but it also support dynamic casting, so you should always cast an integer!

printf

<?php
$var = 1*$var;
?>

 

quite simple

just do some maths with a string and if its a number it will turn into a float/int

ok im getting this error as its stil not converting to int,,, Out of range value adjusted for column 'sel_item_qty' at row 1

 

i know i need 2 use intval()  but does my variable $x  go inside the brackets so its intval($x) ; ?
