    how to apply condition for print values ??of an array

    hello staff www.ads-software.com
    I need help from you again,

    this function shuffle numbers,

    function gen_num()
{
$caracteres = "012345678910111213141516171819";
$mistura = substr(str_shuffle($caracteres),0,15);
print $mistura;
}

    I needed a condition to print or not the numbers at the posts, and the @leglesslizard User helped me. It works perfectly, the big problem down was that each new access to posts, or refresh the kapok, a new number / value was generated, and this could not happen, I needed to write permanently on those values ??in the posts and below the solution but can not apply in arrays!

    function gen_num()
{
global $post;
$mistura = get_post_meta( $post->ID, 'my_custom_meta', true );

if ( '' == $mistura ) {
$caracteres = "012345678910111213141516171819";
$mistura = substr(str_shuffle($caracteres),0,10);
update_post_meta( $post->ID, 'my_custom_meta', $mistura );
}

print $mistura;
}

    I am now trying to make arrays and I can not!

    function shuflenames()
{
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n";
echo $input[$rand_keys[1]] . "\n";
}

    my failed attempt to apply condition with arrays:

    function shuflenames()
{
global $post;
$mixnames = get_post_meta( $post->ID, 'my_custom_meta', true );
if ( '' == $mixnames) {
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
$rand_keys = array_rand($input, 2);
update_post_meta( $post->ID, 'my_custom_meta', $mixnames );
}
echo $input[$rand_keys[0]] . "\n";
echo $input[$rand_keys[1]] . "\n";
}

    but the words change as the condition does not exist. every new access words are changed, they are not actually written in the posts

    Thanks to all, Best Regards.

    Printed values ??were not written permanently in the pages, it change every new access on pages. want a shuffle to all be different, but in the first run he writes permanently, as in the first case not writing, so I made that change with the condition to not write if already there is a value in place, he decided, but I do not make your arrays. I want someone to tell me how to do this with arrays.

    —–

    note that showed a first case that could solve, the values ??in numeric shuffle I managed to get them to be written once, with the solution below it, I want to do that in the second case, a function with arrays, I do not do the function write truly permanent in the posts before the first case, each access generated a new number the pages, never saw the same number now managed to solve with the solution below, each page has a unique number, and ever written, not change more each refresh on the page, not to do with managing arrays ??

    My response in your other thread should work for you:

    You @bcworkz again ?? thank you, that your other help also worked! ?? Now writes permanently on the field! but I need to write more than one name, and I’m trying a few hours and I’m not getting it.

    function gen_num()
{
  global $post;
  $mixnames = get_post_meta( $post->ID, 'fieldnames', true );

  if ( '' == $mixnames ) {
    $input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
    $rand_keys = array_rand($input, 3);
    $mixnames = $input[$rand_keys[1]];
   // $mixnames = $input[$rand_keys[2]];
   // $mixnames = $input[$rand_keys[3]];
    update_post_meta( $post->ID, 'fieldnames', $mixnames );
  }
  // DISPLAYS THE OUTCOME
  print $mixnames;
}

    if I uncomment I break the code ??

    I tried so also, don’t break the code, but does not work :(:

    function gen_num()
{
  global $post;
  $mixnames = get_post_meta( $post->ID, 'fieldnames', true );

  if ( '' == $mixnames ) {
    $input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
    $rand_keys = array_rand($input, 3);
    $mixnames = $input[$rand_keys[0]] . "\n";
    $mixnames = $input[$rand_keys[1]] . "\n";
    $mixnames = $input[$rand_keys[2]] . "\n";
    update_post_meta( $post->ID, 'fieldnames', $mixnames );
  }
  // DISPLAYS THE OUTCOME
  print $mixnames;
}

    I need to show multiple names, how to display multiple input?
    thanks for help me again.

    learned, was only concatenate strings (credits to member LTasty of the stack over flow)

    $mixnames = $input[$rand_keys[0]].$input[$rand_keys[1]].$input[$rand_keys[2]];

    thanks BCWORKZ by help, you helped me a lot!THANKS
