Today I’m going to show simple and easy random number, string and character generator in php. Below I made random string generator that you can give length of string and randomize it first it will give error ignore that ant give length of string and click randomize. i added some style to my application

  
   
    
  
  

  

   length of string:

   


    <?php echo $_SESSION['random_code'];?>


     
  

   

If you want number generator just change the inside the for loop line

$string .= chr(rand(97, 122)); 

To

 ”>$string .= rand(0, 15); 

This is generate number between given length minimum value is ‘0’ and maximum value is ‘15’ Make improvement live comment
