    text
    copied!<p>I have this class i making that works if I keep the constants in the class code, but i wanted to access them from an external file that the user can comment or uncomment out c constant value.</p> <p>it works great this way but I do not want the users rummaging around in the code:</p> <pre><code>class passwordStringHandler { # const PWDALGO = 'md5'; # const PWDALGO = 'sha1'; # const PWDALGO = 'sha256'; # const PWDALGO = 'sha512'; const PWDALGO = 'whirlpool'; /* THIS METHOD WILL CREATE THE SALTED USER PASSWORD HASH DEPENDING ON WHATS BEEN DEFINED */ function createUsersPassword() { $userspassword = 'Te$t1234'; $saltedpassword=''; if ((defined('self::PWDALGO')) &amp;&amp; (self::PWDALGO === 'md5')) { $saltedpassword = md5($userspassword . $this-&gt;pwdsalt); echo("The salted md5 generated hash is: " . $saltedpassword . "&lt;br&gt;"); return $saltedpassword; }elseif ((defined('self::PWDALGO')) &amp;&amp; (self::PWDALGO === 'sha1')){ $saltedpassword = sha1($userspassword . $this-&gt;pwdsalt); echo("The salted sha1 generated hash is: " . $saltedpassword . "&lt;br&gt;"); return $saltedpassword; }elseif ((defined('self::PWDALGO')) &amp;&amp; (self::PWDALGO === 'sha256')){ $saltedpassword = hash('sha256', $userspassword . $this-&gt;pwdsalt); echo("The salted sha256 generated hash is: " . $saltedpassword . "&lt;br&gt;"); return $saltedpassword; }elseif ((defined('self::PWDALGO')) &amp;&amp; (self::PWDALGO === 'sha512')){ $saltedpassword = hash('sha512', $userspassword . $this-&gt;pwdsalt); echo("The salted sha512 generated hash is: " . $saltedpassword . "&lt;br&gt;"); return $saltedpassword; }elseif ((defined('self::PWDALGO')) &amp;&amp; (self::PWDALGO === 'whirlpool')){ $saltedpassword = hash('whirlpool', $userspassword . $this-&gt;pwdsalt); echo("The salted whirlpool generated hash is: " . $saltedpassword . "&lt;br&gt;"); return $saltedpassword; } else echo("No password algro is defined! Edit the [&lt;strong&gt;PWDALGO&lt;/strong&gt;] options in the &lt;strong&gt;systemConfiguration.php&lt;/strong&gt;&lt;br&gt;"); return false; } </code></pre> <p>This works ok cause it is hard coded into the class file:</p> <p>I want it to work using this:</p> <pre><code>require ("../configs/systemConfiguration.php"); class passwordStringHandler { </code></pre> <p>I keep getting the else in my if /else statement it cant find if PWDALGO is defined.</p> <p>or this way</p> <pre><code>class passwordStringHandler { require ("../configs/systemConfiguration.php"); </code></pre> <p>I do not know if this is possible since i keep getting an error, I do not think you can include or require files inside the class scope.</p> <p>in the future if I get this to work I wanted a setup script to check the server to see what encryption types are available and to make a list of the for the user to choose there preferred method of encryption, and then set it automatically for them. and be able to change the encryption method later from a admin control panel.</p>
