  1. POPHP - require_once in multiple pages
    text
    copied!<p>I am using LAMP stack to develop a PHP application. I am using require_once to include class files. I need to use the functions in those class files in more than one PHP page. So, I am including those class files in all the required PHP pages using require_once. But, if I include those class files in more than one page, the PHP file goes blank. It displays nothing. View source also displays nothing.</p> <p>Files: test.php, process.php and class.test.php</p> <p>test.php has</p> <pre><code>&lt;?php session_start(); require_once 'classes/class.test.php'; . Few more classes . . ?&gt; &lt;html&gt; &lt;form name = "myForm" method="POST" action="process.php"&gt; &lt;input type = "text" name="username" value=""/&gt; &lt;input type = "submit" value="Submit" /&gt; &lt;/form&gt; &lt;/html&gt; </code></pre> <hr> <p>process.php</p> <pre><code>&lt;?php session_start(); require_once 'classes/class.test.php'; $obj_test = new test(); $obj_test-&gt;test(); ?&gt; </code></pre> <hr> <p>class.test.php</p> <pre><code>&lt;?php session_start(); require_once 'class.misc.php'; require_once 'config.php'; //DB connection details function test() { $obj_misc = new misc(); $id = $obj_misc-&gt;random_ID(); $username = $_POST['username']; $query = "INSERT INTO test_table VALUES ('$id','$username',NOW()); mysql_query($query); } ?&gt; </code></pre> <p>Now, it returns a blank page. If I comment out the require_once in process.php, the test.php page displays the form, but on submitting the form the process.php throws an error "class test not found". </p> <p>I am struggling with this problem for the past 2 weeks. :( It was working fine before that. I don't understand what went wrong. Please help.</p>
