Multiple Include Function

[Sharif]

In an attempt to create a function that has the ability to include multiple files, this is what I came up with:

function include_files()
{
global $SOURCE;
//List of files to include
$files = array('file.php', 'file2.php');

//Begin loop to include files
foreach($files as $file)
{
include($file);
}
}

I am trying to get past of editing the function to define which files to include. So what can be done so I don't have to edit the $files variable to define which files to include.

pass it to the function when you call it

function include_files($files) {
   if(is_array($files)) {
      foreach($files as $file) {
         include($file);
      }
   }
   else {
      include($files);
   }
}

include_files(array('file.php', 'file2.php'));

That's a good idea (why didn't I think of that?), but can we make it simpler? Say I just want to use the function like this:

include_files('1.php' , '2.php', '3.php');

I'm trying to make it so even the newest of newbs can use it, for someone that doesn't know how to use array() 🙂

You can comma seperate them and create the array yourself. Don't suspect you can just pass unwanted parameters to it though.

Assume this:
include_files('1.php,2.php,3.php');

Something like this should do the trick...

function include_files($files) {
   if(is_array($files)) {
      foreach($files as $file) {
         include($file);
      }
   }
   elseif(strpos(",",$files) !== false) {
      $files = explode(",",trim($files));
      foreach($files as $file) {
         include($file);
      }
   }      

   else {
      include($files);
   }
}

That is a good solution BUT, I don't think it would work if I used varibles to specify the files. Sort of like include_files($FILE1, $FILE2)

[LordShryku]

Why wouldn't that work?

[Sharif]

Well because it isn't an array, it also isn't a string. That's why 🆒

[LordShryku]

Right, right, take a look at [man]func_get_args[/man] in that case.

but you could call it like this

<?php
include_files(array($var1,$var2,$var3));
?>

[Shrike]

define("SYSTEMPATH", "/path/to/files/");
function include_files($files){
  if(is_array($files)){
    foreach($files as $file){
      is_file(SYSTEMPATH . $file)
        and include_once($SYSTEMPATH . $file);
    }
  }else{
    $err = "Argument to include_files() must be array."
    return $err;
  }
}

My 2c 🙂

Okay tried to do something using func_get_args():

function include_files()
{
	$args = func_num_args();

//Begin loop to include files
for ($i = 0; $i < $args; $i++) 
{
	include($i);
}
}

PHP delivered via UPS these errros:

Warning: include_files(0): failed to open stream: No such file or directory in /home/oox/public_html/beta/sources/functions.php on line 26

Warning: include_files(): Failed opening '0' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/oox/public_html/beta/sources/functions.php on line 26

Warning: include_files(): Failed opening '1' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/oox/public_html/beta/sources/functions.php on line 26

func_num_args() is somewhat superfluous since you can say

function include_files()
{
    $args = func_get_args(); // Not func_num_args()
    // We could get the length of $args with func_num_args()
    //Begin loop to include files
    for ($i = 0; $i < count ( $args ); $i++)
    {
        include ( $args[$i] );  // Note $args[$i] not simply $i
    }
}
include_files ( 1, 2, 3 );

Okay tried that with this:

$SOURCE['errors'] = 'errors.php';
$SOURCE['mysql'] = 'mysql.php';

include_files($SOURCE['errors'], $SOURCE['mysql']);

..nope!
