The following is your program. you need some little bit
change on this program.
<?php
include ("db.php");
$result = mysql_query("SELECT ques_id FROM questionbank
order by ques_id limit 5 ");
while($obj=mysql_fetch_array($result))
{
$ad1[$obj['ques_id']]++;//
}
$rand_keys=array_rand($ad1,1); //Did a random array function
echo "First random id = ".$ad1[$rand_keys[0]];
echo "<br>Second random id = ".$ad1[$rand_keys[1]];
?>
Your Mistake
1. in while statement you add $ad1[$obj['ques_id']]++; which
is not assignment statement. It is a increment statement.
The correct answer is $ad1[$obj['ques_id']] = $obj['ques_id'];
2.in array random function You use 1 key but you display random
array value using 2 keys.
$rand_keys=array_rand($ad1,1); //Did a random array function
echo "First random id = ".$ad1[$rand_keys[0]];
echo "<br>Second random id = ".$ad1[$rand_keys[1]];
just change 1 to 2 in array_rand($ad1,2);
The Changes are from while statement.
while($obj=mysql_fetch_array($select))
{
$ad1[$obj['ques_id']] = $obj['ques_id'];
}
$rand_keys=array_rand($ad1,2); //Did a random array function
echo "First random id = ".$ad1[$rand_keys[0]];
echo "<br>Second random id = ".$ad1[$rand_keys[1]];
