Php error bool false

Php error bool false

While waiting for native support for typed arrays, here are a couple of alternative ways to ensure strong typing of arrays by abusing variadic functions. The performance of these methods is a mystery to the writer and so the responsibility of benchmarking them falls unto the reader.

PHP 5.6 added the splat operator (. ) which is used to unpack arrays to be used as function arguments. PHP 7.0 added scalar type hints. Latter versions of PHP have further improved the type system. With these additions and improvements, it is possible to have a decent support for typed arrays.

function typeArrayNullInt (? int . $arg ): void >

function doSomething (array $ints ): void (function (? int . $arg ) <>)(. $ints );
// Alternatively,
( fn (? int . $arg ) => $arg )(. $ints );
// Or to avoid cluttering memory with too many closures
typeArrayNullInt (. $ints );

function doSomethingElse (? int . $ints ): void /* . */
>

$ints = [ 1 , 2 , 3 , 4 , null ];
doSomething ( $ints );
doSomethingElse (. $ints );
?>

Both methods work with all type declarations. The key idea here is to have the functions throw a runtime error if they encounter a typing violation. The typing method used in doSomethingElse is cleaner of the two but it disallows having any other parameters after the variadic parameter. It also requires the call site to be aware of this typing implementation and unpack the array. The method used in doSomething is messier but it does not require the call site to be aware of the typing method as the unpacking is performed within the function. It is also less ambiguous as the doSomethingElse would also accept n individual parameters where as doSomething only accepts an array. doSomething’s method is also easier to strip away if native typed array support is ever added to PHP. Both of these methods only work for input parameters. An array return value type check would need to take place at the call site.

If strict_types is not enabled, it may be desirable to return the coerced scalar values from the type check function (e.g. floats and strings become integers) to ensure proper typing.

same data type and same value but first function declare as a argument type declaration and return int(7)
and second fucntion declare as a return type declaration but return int(8).

function argument_type_declaration(int $a, int $b) return $a+$b;
>

function return_type_declaration($a,$b) :int return $a+$b;

Php error bool false

Much of the confusion about booleans (but not limited to booleans) is the fact that PHP itself automatically makes a type cast or conversion for you, which may NOT be what you want or expect. In most cases, it’s better to provide functions that give your program the exact behavior you want.

function boolNumber ( $bValue = false ) < // returns integer
return ( $bValue ? 1 : 0 );
>

function boolString ( $bValue = false ) < // returns string
return ( $bValue ? ‘true’ : ‘false’ );
>

$a = true ; // boolean value
echo ‘boolean $a AS string = ‘ . boolString ( $a ) . ‘
‘ ; // boolean as a string
echo ‘boolean $a AS number = ‘ . boolNumber ( $a ) . ‘
‘ ; // boolean as a number
echo ‘
‘ ;

$b = ( 45 > 90 ); // boolean value
echo ‘boolean $b AS string = ‘ . boolString ( $b ) . ‘
‘ ; // boolean as a string
echo ‘boolean $b AS number = ‘ . boolNumber ( $b ) . ‘
‘ ; // boolean as a number
echo ‘
‘ ;

$c = boolNumber ( 10 > 8 ) + boolNumber (!( 5 > 10 )); // adding booleans
echo ‘integer $c = ‘ . $c . ‘
‘ ;

?>
Results in the following being printed.

boolean $a AS string = true
boolean $a AS number = 1

boolean $b AS string = false
boolean $b AS number = 0

In other words, if we know what we want out of our program, we can create functions to accommodate. Here, we just wanted ‘manual control’ over numbers and strings, so that PHP doesn’t confuse us.

PHP: Booleans — Manual

https://www.php.net/manual/en/language.types.boolean.php

PHP’s handling of strings as booleans is *almost* correct — an empty string is FALSE, and a non-empty string is TRUE — with one exception: A string containing a single zero is considered FALSE.

Then I remembered that because of the INI syntax both names and values will be trimmed, so the following workaround MAYBE should do the trick: NL = Netherlands ; A whitespace before the name NO = Norway PL = Poland And it works 😉 As long as your co-workers read the comments (which is not always the case) and don’t delete it accidentally.
