Fatal error: Maximum execution time of 30 seconds exceeded

[jlryan87]

Hello everyone. Today I make a code to display numbers 1-20 randomly without repeating any of the numbers. The result is fine but I keep on getting Fatal error: Maximum execution time of 30 seconds exceeded. Personally I don't think PHP will have much trouble going through the loop. Here's the code I have written:

<?

 

$i = 0;

$m = 20;

 

while ($i<$m){

$n = rand(1,20);

if (ereg(" ".$n." ", $k) == 1){

$i -=1;

}else{

$k .= " ".$n." ";

echo " $n ";

$i +=1;

}

}

 

?>

 

Is there any way I can write the code without having the fatal error?

What is wrong with my code? There's no infinite loop and I don't think there is a long loop either.

 

Thanks everyone who gives some help.

One test you can do to make sure you aren't in an infinite loop would be to echo out each number as it's reached in your loop.

 

Outside of that possibility, I haven't seen that particular error yet. Perhaps someone else has.

<?php set_time_limit(0); ?>

Just remove  $i -=1;

and its done .. You dont need to apply -1 here .

Alternatively, why not simply use

$numbers = range(1,20);
shuffle($numbers)

to give yourself a randomly shuffled array of numbers
