Introduction

Creating a log in script using PHP can be easier using the power of strcmp().

What you'll need

You'll need to have a database, or text file and know how to look up the password using the username. This is simply to create a faster, easier, more secure way of comparing the two strings using PHPs built in strcmp() or strcasecmp() functions.

Steps

After accessing your username/password combinations through MySQL, a text file or other methods you can easily compare the string values using strcmp().

if(strcmp($userpass,$passentered)){ //display secure content } else { //ask for username/password combo again }

This is a quick and easy method. If the two strings passed to the function are EXACTLY the same, then the returned value will be 0. If case sensitivity is not necessary then use strcasecmp($a,$b) - which works exactly the same way but ignores case sensitivity.
