Random $var repeating.

Need it to display different everytime.

[sauce]

I'm trying to pull random lines from text file and print them from calling a variable but everytime I call the variable it pritns the same thing. Here is the code:

<?php

$var = file("vars.txt");
$returns = array("\n", "\r");
$var = str_replace($returns, "", $var);
foreach ($var as $num=>$line) {
$var[$num] = strtolower("$line");
}
$n = sizeof($var ) - 1;
$var = $var[rand(1, $n)];

echo $var;
echo $var;
echo $var;
echo $var;
echo $var;
echo $var;

?>

This prints:

line3
line3
line3
line3
line3
line3

When I want it to print each line randomly, like:

line9
line2
line6
line2
line1
line6

Any changes you can see in that code?

thx.

$var_ = $var[rand(1, $n)];
echo $var_;
$var_ = $var[rand(1, $n)];
echo $var_;
$var_ = $var[rand(1, $n)];
echo $var_;
$var_ = $var[rand(1, $n)];
echo $var_;
$var_ = $var[rand(1, $n)];
echo $var_;
?>

Just follow your style, it will be so. But read about delete symbols in the end of line, and you need to look in it more carefully, not the best solution.

Is there any way I can reset this array after if it executed...

like $var_ = $var[rand(1, $n)] - reset

Instead of having to enter:

$var_ = $var[rand(1, $n)];

everytime I echo $var?

[newbie2006]

srand((float) microtime() * 10000000);
$keys = array_rand($var, 2);
echo $var[$keys[0]];
echo $var[$keys[1]];

if you try to put here also the foreach cycle, then possibly you will get what you are looking for.
