if ... else random

[manalnor]

Hello dear friends,

 

Let say we have files

 

red.php

orange.php

blue.php

yellow.php

 

here is the main question

 

if ($any == 1)
{
require_once("red.php");
} else {
xxxxxxxxxxxxxxxxxxxxxxxx
}

 

how to make it else ( show random files )

i mean instead of xxxxxxxxxxxxx it will pick up any file in random way.

 

how to write this !

thanks in advance

$files = glob('*.php');
require($files[array_rand($files)]);

$colors = Array('red.php', 'blue.php', 'orange.php', 'yellow.php');
$max = count($colors) - 1;
$rand = rand(0, $max);
echo "Random Color: {$colors[$rand]}";

 

Careful on Jay's method - you could grab any php file.

True, I did think that myself, but it was assuming that all the files are in a separate folder with the .php extension. If they aren't then go with a normal array method or give your files a certain suffix such as

red.color.php

then search for *.color.php instead of just *.php

thanks so much for both ways and i understood that Jay method will take any *.php file with it but will be fine is the files in /templates dir.

 

 

one last question, is that possible to be in that way

 

if ($wpic == red) {
require_once("red.php");
} else if($wpic == blue) {
require_once("blue.php");
} else if($wpic == yellow) {
require_once("yello.php");
} else {
xxxxxxx ddubs code for random xxxxxxxx
}

 

 

i mean is it possible to use chain of (else if) i mean many times.

Yea thats fine, or you can research "switch"

 

switch($wpic) {
  case $wpic == 'red' :
    require_once("red.php");
    break;
  case $wpic == 'blue' :
    require_once("blue.php");
    break;
...etc
  default :
  //insert random code here...
}

Yes, but in this case it is inefficient

$colors = array('red', 'blue', 'yellow');

if (in_array(strtolower($wpic), $colors))
{
    $require_file = strtolower($wpic) . '.php';
}
else
{
    $require_file = $colors[array_rand($colors)] . '.php';
}

require_once($require_file);
