28 kwi 2015 · Amber is right and if I may add a useful information type casting (adding a "(int)" before your expression ) is 300 to 600% faster than intval. So if your purpose is not to dealing with other bases than decimal, I recommend using: (int) $something
intval converts doubles to integers by truncating the fractional component of the number. When dealing with some values, this can give odd results. Consider the following: print intval ((0.1 + 0.7) * 10); This will most likely print out 7, instead of the expected value of 8.
29 cze 2012 · In contrast to casting, intval also allows non-decimal bases. Additionally, every programmer knows functions and can easily look them up at php.net/function, whereas casts are not as widely known.
PHP Casting Strings and Floats to Integers. Sometimes you need to cast a numerical value into another data type. The (int), (integer), and intval() functions are often used to convert a value to an integer.
PHP provides various methods for type casting, including using casting operators like (int), (float), (string), (bool), and (array), as well as functions like intval(), floatval(), and strval(). Type casting allows developers to explicitly define the desired data type for a variable, ensuring consistent behavior and accurate calculations.
Casting a variable to an integer using (int) is simply using a function that PHP provides named settype. This function takes two arguments; the first argument is the variable you want to convert, and the second is the data type you want to convert it to.
If the value is a string with a valid octal number and the base is 8, the intval () function returns a corresponding octal number. When the base is "0", the conversion of value takes place on the basis of character prefix. If the value starts with 0X or 0x, a hexadecimal number is returned.
