Generate An Authentication Code in PHP
<?php# This particular code will generate a random string# that is 25 charicters long 25 comes from the number# that is in the for loop$string = "abcdefghijklmnopqrstuvwxyz0123456789";for($i=0;$i<25;$i++){ $pos = rand(0,36); $str .= $string{$pos};}echo $str;# If you have a database you can save the string in # there, and send the user an email with the code in# it they then can click a link or copy the code# and you can then verify that that is the correct email# or verify what ever you want to verify?> 5. HTTP Redirection in PHP
<?php header('Location: http://you_stuff/url.php'); // stick your url here?>
Following is the PHP code to create the JSON data format of above example using array of PHP.
$json_data = array ('id'=>1,'name'=>"rolf",'country'=>'russia',"office"=>array("google","oracle"));echo json_encode($json_data);
Following code will parse the JSON data into PHP arrays.
$json_string='{"id":1,"name":"rolf","country":"russia","office":["google","oracle"]} ';$obj=json_decode($json_string);//print the parsed dataecho $obj->name; //displays rolfecho $obj->office[0]; //displays google

'<html><head>'."n". '<title>404 Not Found</title>'."n". '</head><body>'."n". '<h1>Not Found</h1>'."n". '<p>The requested URL '. str_replace(strstr($_SERVER['REQUEST_URI'], '?'), '', $_SERVER['REQUEST_URI']). ' was not found on this server.</p>'."n". '</body></html>'."n"; exit;}# In any file you want to connect to the database, # and in this case we will name this file db.php # just add this line of php code (without the pound sign):# include"db.php";?>
