How to get random array from multidimensional array in php? - php

Question

I am trying to get random array:
for example:
$navItems= array(
array(
slug => "top10.php",
title => "Top 10 geriausi"
),
array(
slug => "index.php",
title => "Pagrindinis"
),
array(
slug => "top-prasciausi.php",
title => "Top 10 prasciausi"
),
array(
slug => "visi-politikai.php",
title => "Visi politiki"
),
);
and after that use this random array inside foreach loop like this:
foreach ($navItems as $item) {
echo "<li class=\"hov\">$item[title]<li>";
}
Instead of $navItems variable i want to use that random arrays from $navItems array

Answer 1

You can use shuffle to randomize the array
Note: If you are trying to pick one from the array, you can use shuffle and select the first element of the array.
$navItems = array(
array(
'slug' => "top10.php",
'title' => "Top 10 geriausi"
),
array(
'slug' => "index.php",
'title' => "Pagrindinis"
),
array(
'slug' => "top-prasciausi.php",
'title' => "Top 10 prasciausi"
),
array(
'slug' => "visi-politikai.php",
'title' => "Visi politiki"
),
);
shuffle( $navItems );
echo "<pre>";
print_r( $navItems );
echo "</pre>";
This will result to something like:
Array
(
[0] => Array
(
[slug] => index.php
[title] => Pagrindinis
)
[1] => Array
(
[slug] => visi-politikai.php
[title] => Visi politiki
)
[2] => Array
(
[slug] => top10.php
[title] => Top 10 geriausi
)
[3] => Array
(
[slug] => top-prasciausi.php
[title] => Top 10 prasciausi
)
)
