I would simply look for a   GET variable and redirect the user if it s not correct    lt  php  pass     GET  pass    if  pass     my-secret-password       header  Location  http   www staggeringbeauty com         gt    Now  if this page is located at say  http   example com secrets files php  You can now access it with  http   example com secrets files php pass my-secret-password Keep in mind that this isn t the most efficient or secure way  but nonetheless it is a easy and fast way   Also  I know my answer is outdated but someone else looking at this question may find it valuable

you can specify a password in your php code and only allow users that has the secret url   mywebsite com private php pass secret   in your file    lt  php      if isset   GET  pass    amp  amp    GET  pass     secret                 put your code here             else             echo  you re not allowed to access this page            gt

A simple way to protect a file with no requirement for a separate login page - just add this to the top of the page   Change secretuser and secretpassword to your user password    user     POST  user     pass     POST  pass     if    user     secretuser   amp  amp   pass     secretpassword          echo   lt html gt  lt body gt  lt form method  POST  action      SERVER  REQUEST URI      gt              Username   lt input type  text  name  user  gt  lt  input gt  lt br  gt              Password   lt input type  password  name  pass  gt  lt  input gt  lt br  gt               lt input type  submit  name  submit  value  Login  gt  lt  input gt               lt  form gt  lt  body gt  lt  html gt        exit

Not exactly the most robust password protection here  so please don t use this to protect credit card numbers or something very important   Simply drop all of the following code into a file called  secure php   change the user and pass from  admin  to whatever you want  Then right under those lines where it says include  secure html    simply replace that with the filename you want them to be able to see   They will access this page at  YouDomain com secure php  and then the PHP script will internally include the file you want password protected so they won t know the name of that file  and can t later just access it directly bypassing the password prompt   If you would like to add a further level of protection  I would recommend you take your  secure html  file outside of your site s root folder   public html   and place it on the same level as that directory  so that it is not inside the directory  Then in the PHP script where you are including the file simply use      secure html    That       means go back a directory to find the file  Doing it this way  the only way someone can access the content that s on the  secure html  page is through the  secure php  script    lt  php  user     POST  user     pass     POST  pass     if  user     admin   amp  amp   pass     admin             include  secure html      else       if isset   POST          gt                lt form method  POST  action  secure php  gt              User  lt input type  text  name  user  gt  lt  input gt  lt br  gt              Pass  lt input type  password  name  pass  gt  lt  input gt  lt br  gt               lt input type  submit  name  submit  value  Go  gt  lt  input gt               lt  form gt       lt        gt

Some easy ways  Use Apache s digest authorization  Use lighttpd s digest authorization  Use php s header digest authorization    If you want you can also make it so only certain ip addresses can login      really easy with lighttpd  Update  I will post some examples soon  so don t vote down for no examples  i just need to get some down for this answer   If you want to use sessions the following is the best way to go     admin php session start    if    SESSION  AUTH        require once  login php     Do stuff  we are logged in      login php session start    if   REQUEST  username       user   amp  amp    REQUEST  password       pass         SESSION  AUTH     true  else   SESSION  AUTH     false    This logs you out if you visit this login script page without login details   if   SESSION  AUTH        require once  admin php     This method does not contain the examples for above but you seamed interested in this method  The other method examples are still to come  I have not got enough time to get it for apache or lighttpd settings and the php header auth  http   php net manual en features http-auth php Will do

This is a bit late but I wanted to reply in case anyone else came upon this page and found that the highest reply was a bit off  I have improved upon the system just a tad bit  Note  it is still not amazingly secure but it is an improvement   First prepare your password salts file   hash generate php     lt  php    user    Username      please replace with your user   pass    Password      please replace with your passwd     two   was missing    useroptions     cost    gt  8      userhash      password hash  user  PASSWORD BCRYPT   useroptions     pwoptions       cost    gt  8      passhash      password hash  pass  PASSWORD BCRYPT   pwoptions     echo  userhash   echo   lt br   gt     echo  passhash      gt    Take your output  userhash and  passhash and put them in two text files  user txt and pass txt  respectively  Others have suggested putting these text files away above public html  this is a good idea but I just used  htaccess and stored them in a folder called  stuff    htaccess   deny from all   Now no one can peek into the hash  Next up is your index php   index php    lt  php  user         prevent the  no index  error from   POST  pass       if  isset   POST  user          check for them and set them so      user     POST  user      if  isset   POST  pass          so that they don t return errors      pass     POST  pass            useroptions     cost    gt  8       all up to you  pwoptions       cost    gt  8       all up to you  userhash      password hash  user  PASSWORD BCRYPT   useroptions      hash entered user  passhash      password hash  pass  PASSWORD BCRYPT   pwoptions       hash entered pw  hasheduser    file get contents  stuff user txt       this is our stored user  hashedpass    file get contents  stuff pass txt       and our stored password   if   password verify  user   hasheduser    amp  amp   password verify  pass  hashedpass              the password verify is how we actually login here        the  userhash and  passhash are the hashed user-entered credentials        password verify now compares our stored user and pw with entered user and pw      include  pass-protected php      else           if it was invalid it ll just display the form  if there was never a   POST        then it ll also display the form  that s why I set  user to    instead of a   POST        this is the right place for comments  not inside html       gt         lt form method  POST  action  index php  gt      User  lt input type  text  name  user  gt  lt  input gt  lt br  gt      Pass  lt input type  password  name  pass  gt  lt  input gt  lt br  gt       lt input type  submit  name  submit  value  Go  gt  lt  input gt       lt  form gt       lt  php

Not the solution  but for your interest  HTTP authentication only works  when PHP runs as Apache module  Most hosters provide PHP as CGI version only
