PHP is the most widely used web based programming language that powers millions of websites including some of the most popular ones like Facebook. Here are 21 really useful and handy PHP code snippets that every type of PHP developer will find useful.
1. Human Readable Random String
This code will create a human readable string that will look more close to dictionary words, useful for captchas.
/**************
*@length - length of random string (must be a multiple of 2)
**************/
function readable_random_string($length = 6){
$conso=array("b","c","d","f","g","h","j","k","l",
"m","n","p","r","s","t","v","w","x","y","z");
$vocal=array("a","e","i","o","u");
$password="";
srand ((double)microtime()*1000000);
$max = $length/2;
for($i=1; $i<=$max; $i++)
{
$password.=$conso[rand(0,19)];
$password.=$vocal[rand(0,4)];
}
return $password;
}
2. Generate a Random String
If you don’t need human readable string, then use this function instead, which will create a random string you can use for user id’s etc.
