require-once

I was writing an web app in PHP, when I encountered a strange situation. To illustrate my problem, consider a web app of this structure: / index.php f1/ f1.php f2/ f2.php Contents of these files: index.php: <?php require_once("f1/f1.php"); ?> f1.php: <?php require_once("../f2/f2.php"); ?> f2.php: blank now when I try to open index.php in my browser I get this error: Warning: require_once(../f2/f2.php) [function.require-once]: failed to open stream: No such file or directory in /var/www/reqtest/f1/f1.php on line 2 Fatal error: require_once() [function.require]: Failed opening required '../f2/f2

I am trying to require my "library" files from php files in different folders, but it gives errors when trying to access them from a subfolder. For example I have such a directory: + home - file1.php ++ subfolder - file2.php ++ libraries - code_generator.php - database_library.php code_generator.php also depends on the other library: (LINE 25) require_once(realpath("./libraries/database_library.php")); //this works fine when called from file1.php, but not from file2.php I try to call code_generator from ./subfolder/ file2.php like: chmod("../libraries/codegenerator.php", 0777); // for the

Is it correct to require_once? where and how would you put it include path? Should it not be in a application.ini or bootstrap? EXAMPLE: require_once 'Zend/View/Helper/Abstract.php'; // @question - is this correct - where and // how would you put it include path class Zend_View_Helper_Translate extends Zend_View_Helper_Abstract { } David Weinraub Generally speaking, you can avoid require_once calls almost entirely by appropriately using Zend_Loader_Autoloader . Of course, the key is "appropriate". Typically, your public/index.php sets the include_path to be the library folder. Then, if you are

My webapp has a buch of modules. Each module has a 'main' php script which loads submodules based on a query sent to the main module: //file: clientes.php //check for valid user... //import CSS and JS... switch( $_GET["action"] ) { case "lista" : require_once("clientes.lista.php"); break; case "listaDeudores" : require_once("clientes.listaDeudores.php"); break; case "nuevo" : require_once("clientes.nuevo.php"); break; case "detalles" : require_once("clientes.detalles.php"); break; case "editar" : require_once("clientes.editar.php"); break; default : echo "<h1>Error</h1><p>El sitio ha

Recent versions of PHP have a cache of filenames for knowing the real path of files, and require_once() and include_once() can take advantage of it. There's a value you can set in your php.ini to set the size of the cache, but I have no idea how to tell what the size should be. The default value is 16k, but I see no way of telling how much of that cache we're using. The docs are vague: Determines the size of the realpath cache to be used by PHP. This value should be increased on systems where PHP opens many files, to reflect the quantity of the file operations performed. Yes, I can jack up the

I am using require_once like this require_once('../mycode.php') I am developing a wordpress plugin. My plugin folder is yves-slider where I have a file called yves-slider.php and a folder called admin. Inside admin folder I have a file called admin.php.
