php convert string to boolean
/**
* Strings always evaluate to boolean true unless they have a
* value that's considered "empty" by PHP (taken from the
* documentation for empty):
* "" (an empty string) evaluates as false.
* "0" (0 as a string) evaulates as false.
* If you need to set a boolean based on the text value of a
* string, then you'll need to check for the presence or
* otherwise of that value.

The is_bool() function checks whether a variable is a boolean or not. This function returns true (1) if the variable is a boolean, otherwise it returns false/nothing.php boolean
Booleans can be one of two constants:
true
false
These values are not case sensitive, therefore true is the same as TRUE
booleans are also often used in control structures, either directly or as
a result of an operation. For example:
if ($waterDrankToday > 3.7) {
echo "Good work staying hydrated!";
if ($havingABadDay)
hug();
}
else
echo "You should drink more water";Copyright © 2021 Codeinu
