I want to check values are present in the array and print one random value, but it is giving undefined index error
Here is the code
<?php
$agents = array(9986344xxx,9663275yyy);
function agent(){
global $agents;
if (in_array(9986344xxx,$agents) || in_array(9663275yyy, $agents)) {
$random = array_rand($agents);
echo $agents[$random[0]];
}
else{
echo "notfound";
}
}
agent();
array_rand(array $array [, int $num = 1 ]) returns either an array of keys, if $num is defined and > 1, either a single value.
Since you don't set the second parameter, it returns a single numeric value, being the randomly choosen numeric key of the array, 0 or 1.
Change your code to this to fix that problem :
$agents = array('9986344xxx','9663275yyy');
function agent(){
global $agents;
if (in_array('9986344xxx',$agents) || in_array('9663275yyy', $agents)) {
$random = array_rand($agents);
echo $agents[$random]; // <------------- notice this
}
else{
echo "notfound";
}
}
agent();
