Call dynamic Function with unknown number of params
(3 answers)
Closed 8 years ago.
I want to do something like that:
call_user_func(array('Class', 'Method'), implode(", ", $array));
Is it possible? The imploded string contains a couple of expressions. In this shape however, if $array contains 2 elements, I get an error that Class::method() needs 2 parameters, not 1.
How can I solve this?
You want call_user_func_array instead.
call_user_func_array(array('Class', 'Method'), $array);

I have this code: 37,40,42,46,49,54,56,57 now I wanna separate each number and convert all numbers to an Array.
The array that I want is:
array(37,40,42,46,49,54,56,57)
You can use explode() like this:
$string = "37,40,42,46,49,54,56,57";
$array = explode("," , $string);

I'm learning PHP http://php.net/manual/en/migration70.new-features.php and in the following example, I don't understand ... prepended with the $ints parameter in the function definition.
<?php
// Coercive mode
function sumOfInts(int ...$ints)
{
return array_sum($ints);
}
var_dump(sumOfInts(2, '3', 4.1));
Can anybody please tell me what those dots are for?
Thanks.
that means that when you call that function, you can pass X integers and the function will process them, doesn't matter how many are they. If you call sumOfInts(3,4,6,2,9) or sumOfInts(3,2,9), the function works, no matter how many arguments you pass

if i solve this i will have my desired result for any expert this will take few minutes to guess and i am stuck in this from last 2 hours searching and googling but couldn't found the one i want. Okay so here is the thing ...
I am sending data through ajax to my php by doing JSON.stringify and receving that that to my php in the form of this
{"0":["BE","test","test","1993"],"1":["HSSC","test","test","1995"]}
All i want to do is to get the values and insert them to the separate variables.
You need to use json_decode to convert the string to array. You can pass the second parameter to this method to convert this to array instead of object. Then you can retrieve the data like
$string = '{"0":["BE","test","test","1993"],"1":["HSSC","test","test","1995"]}';
$array = json_decode($string, true);
print_r($array[0][0]);
Here's the example of it https://repl.it/HhI8/1

I have the following string
sender=48&destination=51&message=hi+good&sender=48&destination=49&message=good+boy
Please help me convert that into PHP array as following
array = array(
'sender'=>48,
'destination'=>51,
'message'=>hi+good,
'sender'=>48,
'destination'=>49,
'message'=>good+boy
);
Note: Its not PHP GET.
This should work as inteded, to solve this problem, you just need to use explode() correctly, otherwise it's easy.
Here you go :
$firstarr=explode('&',$yourstring);
$desiredarr=array();
foreach($firstarr as $pair)
{
$exp_pair=explode('=',$pair);
$desiredarr[$exp_pair[0]]=$exp_pair[1];
}
print_r($desiredarr);
If it is from query string then you can just use $_REQUEST otherwise you need to explode() string using & as separator. Then for each item in array that explode() generate, you split with = and add it to final array
or using parse_str().

My chain in PHP is like the following:
$chain = "m=toto&i=12&a=new";
How to get m, i and a values ?
Thanks.
Try This:
<?php
$chain = "m=toto&i=12&a=new";
parse_str($chain,$array);
This will create an array named $array containing all values you can access them as $array['m']
You can Print all this by:
print_r($array);
