rand and for problems

[Patrick3002]

Hi, i have a script that is supposed to created a random 10 digit number... It was working, then i changed something and now it doesn't work. I can't remember what i changed or how to get it to work now...rediculous.

 

 

<?php

$pattern = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
for($i=0;$i<10;$i++) {
    $rndpass = $pattern{rand(0,35)};

} 

echo $rndpass;

?>

 

If anyone can help get it going again that would be greatly appreciated!

You're overwriting your $rndpass variable with each loop. You need to be adding to it:

<?php
$rndpass = '';
$pattern = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
for($i=0;$i<10;$i++) {
    $rndpass .= $pattern{rand(0,35)};

} 

echo $rndpass;
?>

You can either treat your string as an array:

$rndpass = $pattern[rand(0,35)];

 

or as a string

$rndpass = substr($pattern, rand(0,35), 1);

exactly what artacus said.

Except with the dot like Obsidian said.

 

Actually I tried the $pattern{n}, and it worked. But its not a syntax I'm familiar with.

The manual is a bit confusing about this issue.

In the substr() function documentation it says single characters can be accessed by using curly braces ({}). In the part about strings in the manual, it says using square brackets (like in arrays) is recommended, and that the use of curly braces will be deprecated as of PHP 6.

 

But they both work
