28 kwi 2015 · One thing to note about the difference between (int) and intval(): intval() treats variables which are already ints and floats as needing no conversion, regardless of the base argument (as of PHP 5.3.5 at least).
9 lut 2015 · Not really big differences, it's just about what feels more comfortable for you. Only with intval you can change the base of the int, but if you work with decimal numbers, it does not have any real advantages compared to other (int).
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.
Casting in PHP is done with these statements: (string) - Converts to data type String. (int) - Converts to data type Integer. (float) - Converts to data type Float. (bool) - Converts to data type Boolean. (array) - Converts to data type Array. (object) - Converts to data type Object. (unset) - Converts to data type NULL.
Every PHP developer at some point in time has used both (int) and intval for type casting. They are both very similar and work almost identically. However, there are certain situations where one is preferred over the other. Let’s start by understanding the basics of each function.
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.
Let’s take some examples of using the type casting operators. Cast to an integer. To cast a value to an integer, you use the (int) type casting operator. The (int) operator casts a float to an integer. It’ll round the result towards zero. For example: <?php echo (int) 12.5. '<br>'; // 12 echo (int) 12.1. '<br>'; // 12 echo (int) 12.9.
