Need help with this

andrenym00

I'm looking to shuffle content on a page so it's always changing order, for example:

hello, goodbye, maybe, tomorrow would then be goodbye, tomorrow, maybe, hello and so on

I found a code on the internet but I was hoping to see if it's correct

For some reason the first word is not centered but to the left of the page? For example:

Hello

LIST
Goodbye
Yes
No
OK
USA
LIST

I could pm the page I'm having a problem with if someone is willing to help

<?php
$string_array = array
('Hello','Goodbye','Maybe','Yes','No','OK','USA');
$text = "";

$string_count = count($string_array);

for($x=0; $x<$string_count;$x++){
$y = 0;
$temp_array = array();

//reset internal pointers for $string_array
foreach($string_array as $key => $value){
$key = $y;
$temp_array[$key] = $value;
$y ++;
}

$string_array = $temp_array;
//generate a random number of appropriate size
$random_number = rand(0,(count($string_array)-1));
//get the text from the array
$string = $string_array[$random_number];
//make a temp array from that string
$piece = array($string);
//delte the string that was used from the array
$string_array = array_diff($string_array,$piece);
//add that string to the part to be printed.
$text .= "$string<center>";

}

echo $text;
?>

I would simplify things by using [man]shuffle[/man], and also get rid of the deprecated <center> tag:

<?php
$string_array = array
('Hello','Goodbye','Maybe','Yes','No','OK','USA');
shuffle($string_array);  // randomize the order
echo = "<p style='text-align:center'>" . implode("<br />\n", $string_array) . "</p>\n";

Unless I'm missing some other aspect of this, that's really all you should need.

I appreciate the quick response. I have 30 words, how about instead of shuffling all 30 , only shuffling 5 out of the 30?

I found this but it only shuffles 2:

<?php
srand((float) microtime() * 10000000);
$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";
?>

Do I change ($input, 2); to ($input, 5); ?

You could do that (changing 2 to 5) and then do a foreach loop:

$string_array = array('Hello','Goodbye','Maybe','Yes','No','OK','USA');
$rand_keys = array_rand($string_array, 5);
echo "<p style='text-align: center'>\n";
foreach($rand_keys as $key)
{
   echo $string_array[$key]."<br />\n";
}
echo "</p>\n";
