Random String
Just some functions for generating random strings in PHP.
function randstr($len=8, $chars='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789') {
$i = 0;
$str = '';
$randmax = strlen($chars)-1;
for($i=0; $i<$len; ++$i) {
$str .= $chars[mt_rand(0,$randmax)];
}
return $str;
}
function randkey($len=32) {
return randstr($len, '`1234567890-=qwertyuiop[]\\asdfghjkl;\'zxcvbnm,./ ~!@#$%^&*()_+{}|:"<>?');
}
$i = 0;
$str = '';
$randmax = strlen($chars)-1;
for($i=0; $i<$len; ++$i) {
$str .= $chars[mt_rand(0,$randmax)];
}
return $str;
}
function randkey($len=32) {
return randstr($len, '`1234567890-=qwertyuiop[]\\asdfghjkl;\'zxcvbnm,./ ~!@#$%^&*()_+{}|:"<>?');
}
randkey is good for generating salt strings and such, randstr is good for stuff like short URLs. Of course, you can pass in whatever characters you want.
