[Resolved] array_rand and foreach

[spighita]

Hi:
I would like to know how to use the function foreach with array_rand.

This is an example of what I would like to do.

$colors=array('red','green','blue','white','black');

$sc=array_rand($colors,2);

That is the array.

Now what I would like to achieve

 echo $colors[$sc[0]];
echo $colors[$sc[1]];

But achieve it using foreach

foreach($colors[$sc] as $c => $r){
	echo $c ."=>".$r;
}

I get this error

Warning: Illegal offset type in C:\www\test.php on line 5

line 5 would be the foreach function.

Thanks inm advance for anyone who helps.

you would need this...

foreach($sc as $c){ 
    echo $c ."=>".$colors[$c]; 
}

basically you use the foreach to get EACH value from the $sc array (which in this case each of those values is the KEY you want from the colors array) - then apply those keys as $c to the colors array to get the value of they key from $colors
