[sacox]

Suppose I have this array

2,B

3,C

4,D

5,E

 

How to random the array but only the numeric index (1 to 5)

Did you mean that you have an array like the following (regardless of how the code is written)

<?php
$arr = array(
1 => "A",
2 => "B",
3 => "C",
4 => "D",
5 => "E"
);

it is 2 dimentions array like this

 

$data=array(

0=>array("1","A"),

1=>array("2","B"),

2=>array("3","C"),

3=>array("4","D"),

4=>array("5","E")

)

And what part then do you want randomized?

 

You might simply be looking for....

 

shuffle($data)

 

which will randomize the first dimension.

There is the shuffle function, you didn't exactly give many details so I'm not sure if that's appropriate.

I'm sorry it's my mistake,

I have this script to get 3 unique random data out of 10

 

$array = range(0, 10);

$keys = array_rand($array, 3);

echo $array[$keys[0]]; echo "<br />";

echo $array[$keys[1]]; echo "<br />";

echo $array[$keys[2]]; echo "<br />";

 

and now I want to use 2 dimensions array

 

$data=array(

0=>array("1","A"),

1=>array("2","B"),

2=>array("3","C"),

3=>array("4","D"),

4=>array("5","E")

)

 

how to get 2 unique random data from it?

What is it you want to display? without that being clear it's hard for someone to help you out

[ignace]

$keys = array_rand($array, 2);
echo $array[$keys[0]][0]; // 1
echo $array[$keys[1]][1]; // E

thanks ignace i got the idea
