How can Use this argument test() function parameter.


Use func_get_args()
<?php
function test(){
print_r(func_get_args());
}
test(58,1,"world","hello");
Output:
Array

[0] => 58
[1] => 1
[2] => world

Can somebody explain me this code? I don't understand why it outputs 21.
<?php
function math($t){
if($t==0)
return 0;
return $t+ math($t-1);
}
echo math(6);
?>
It will echo 21. I have no idea how it got this result.

The function is recursive, it calls itself until it gets to 0, then adds all the previously returned values (6,5,4,3,2,1).
function math($t){
if($t==0)
return 0;
return $t+ math($t-1);
}
echo math(6);
So on loop one it gets 6 then 6-1 = 5 so math gets called again with 5 this time and so on. Take a look at http://sandbox.onlinephpfunctions.com/code/e228f3b696c5058efee03fa978a09179c1f2ffbb.

Thanks you

Use regex /n(\d+)\((.+?)\)/ to find patern and array_combine to get result
$str = 'n97(nok)_100(ok)_n41(145)_23(ok)';
if(preg_match_all('/n(\d+)\((.+?)\)/', $str, $m)) {
$res = array_combine($m[1], $m[2]);
}
print_r($res);

I want to define a constant of array. How can I do that?
define("CREDIT_REPORT_FAIL", "FAIL");

In Laravel you can define an array in a config file:
'some_array' => [
'var' => 'value',
'another_var' => 'value'
],
And then you config() global helper to get the array:
config('config_file.some_array')

Please Try This Code
Define Code
define('TEST', serialize(array(1, 5, 10, 15)));
Use
$data = unserialize(TEST);

I have such this array in PHP, How can i convert the one and two and three into variables for each one (i have just pasted first array of the items)?
Array
(
[encoding] => utf-8
[title] => arrays
[link] => arrays.com
[items] => Array
(
[0] => Array
(
[one] => this is one
[two] => arrays.com
[three] => This IS my array here
)
)
[items_count] => 100
[cached] => 0
)

You can use PHP's extract() function:
extract($array['items'][0]);

a realy simple way is the php function extract. It provides you the keys of an array as variables in your current scope.
In your case just write extract($array['items'][0]);
Now you can access the variables $one, $two and $three.

you can do this
list($one,$two,$tree) = $Your_Array['items'][0];

I have written some php code, trying what is to assign a string (tag_of_organization) to a variable and then latter to assign it to array newvar. As i am totally new to php and search a lot for it but cannot find anything, so i am asking it here how to do this. here it is
$organ='tag_of_organization';
$newvar = array();
$newvar["tag_of_organization"] =$organ;

Try with:
$newvar[$organ] = $organ;

You are already correct. put print_r to test print your array
$organ='tag_of_organization';
$newvar = array();
$newvar["tag_of_organization"] =$organ;
print_r($newvar);
Output
Array ( [tag_of_organization] => tag_of_organization )
Update
you want dynamic result
$organ='tag_of_organization';
$newvar = array();
$newvar[$organ] =$organ;
print_r($newvar);
Output
Array ( [tag_of_organization] => tag_of_organization )
