you can use:
include($filename); // will give a warning if the file is not found
include_once($filename); // same, but only includes if the file isn't already included
require($filename); // will stop the script if the file is not found
require_once($filename); // same, but only includes if the file isn't already included

How do you create a script to upload a file in PHP?
Hope your requirement is to upload a file to server . follow this code. $files=array(); $file=handleUpload($_FILES); function handleUpload($upload_file){ if(!$upload_file) return; $files=array(); $file->file_orig_name = $upload_file['name']; $file->file_size = $upload_file['size']; $path_parts = pathinfo($file->file_orig_name); $file->file_extension = strtolower($path_parts['extension']); $file->file_mime_type = $upload_file['type']; $file->file_tmp_name = $upload_file['tmp_name']; return $files; }
What does the function require-once do in php?
PHP maintains four direct functions for bringing in code from other files/sources. require() and require_once() bring code in from another source and PHP will refuse to run if it cannot load those files. include() and include_once() bring code in just the same, but your script will continue to run if those files could not be parsed. Thus you would use it if the code is optional and not necessary. The _once() functions tell PHP to keep a list of required/included files so far and ignore the request if it's already been done somewhere else. Otherwise, it'll parse the file twice and could cause your script to fail because the functions, classes, etc defined during the second load would conflict with those loaded the first time.
How do you retrieve and save PHP variables using text files?
Saving and retrieving PHP variables to and from a text file is bad programming practice in most cases, and can have repercussions (for example, the possibility of a variable changing between any two times running a script, and the script not being prepared for the new value).There are better alternatives available, such as using a database system like MySQL, or a more standardized "text file" system using INI files. See the related links for information on MySQL and INI files. With that in mind:There are many routes to making a script that retrieves and saves PHP variables in a text file, but a simple and common one may use the functions file_get_contents and file_put_contents, along with others like preg_match.file_get_contents($filename) can be used to get the variables (and any other content) in our text file.file_put_contents($filename) can be used to save variables to our text file.preg_match($pattern, $string) can be used to validate a string and see if it matches the specified pattern.See the related links for more information on these variables.Before actually writing the script, a format of writing our variables (and their values) should be planned out. Simply put, what should your text file look like? For this example, we'll assume a style like this:var1 = "something"var2 = TRUEvar3 = 59The style rule we're going to use here is the name of a variable, followed by a space, an equal sign, and another space, then the PHP syntax of a variable value (var1 will be a string, var2 will be a boolean, var3 will be an integer, and such). A new line specifies a new variable declaration.Now lets go ahead and write our script. The one in this example will be called "index.php", but any name will do.index.php
