in php func_get_args — Returns an array comprising a function's argument list
it returns numeric index array
is there any function/way in php by which we get associative array i.e. key=>value pair
i m explaining with example:
###test.php
<?php
function foo() {
include './fga.inc';
}
$x=20;
$y=30;
foo($x, $y);
?>
###fga.inc
<?php
$args = func_get_args();
echo "<pre>";
print_r($args);
echo "</pre>";
?>
which should returns
array (
'x'=> 20,
'y' => 30,
)
You can't do this within your foo() function, because PHP doesn't pass the variable names to your function, only their values. Plus, PHP doesn't support named arguments in functions, and it doesn't seem like it'll do so anytime soon.
A workaround would be to pass an associative array as a single argument to your function. You can use compact() to collate the variables in the calling scope that you want to pass, for example:
function foo($args) {
echo "<pre>";
print_r($args);
echo "</pre>";
}
$x = 20;
$y = 30;
foo(compact('x', 'y'));
Output:
Array
(
[x] => 20
[y] => 30
)
