php cast string to int



for more information, see the section on floating point numbers in the php manual ( php.net/manual/language.types.double.php) also note that if you try to convert a string to an integer, the result is often . however, if the leftmost character of a string looks like a valid numeric value, then php will keep reading the  you don't typically need to do this, since php will coerce the type for you in most circumstances. for situations where you do want to explicitly convert the type, cast it: $num = "."; $int = (int)$num; $float = (float)$num;. you can remove the spaces before casting to int : (int)str_replace(' ', '', $b);. also, if you want to strip other commonly used digit delimiters (such as , ), you can give the function an array (beware though in some countries, like mine for example, the comma is used for fraction notation):

déc. often in computer systems "" is greater than "" because it doesn't interpret it as a number. not so in php, which, even if both are strings, realizes they are numbers and removes the need for a cast):. javascript console.log("" > "" ? "true" : "false"); true. php echo "" > "" ? "true" : "false"; false! php is a looselytyped language, i.e it will not impose strict rules when initializing or assigning a value to a variable. there are numerous methods to accomplish what you ask in php. you can change an integer to string by enclosing the integer note: there is one modification to the rules. remember, you cannot use the aliases for certain primitives in hack (e.g, boolean instead of bool ). <?hh namespace hack\userdocumentation\types\inference\examples\unresolved; function cast(): bool { $a = ""; $a = (int) $a; $a = (bool) $a; $a = (float) $a; not allowed,  variable type and type conversion in php. when you declare a variable in php, you do not specify its type. its type depends on the value it currently holds. for example, the following variable has been assigned a string value. so it's type is currently string , as we verify by using the gettype function: $val = 'hello there!'
