It will use memory mapping techniques if supported. filegetcontents () is the preferred way to read the contents of a file into a string. On failure, filegetcontents () will return false. A simple way to have the absolute path of the initially executed script, in that script and any other script included with include, require, require_once is by using a constant and storing there the current script path at beginning of the main script: define( 'SCRIPT_ROOT', _FILE_ ) Sometimes you need to find the absolute server path of the current file in order to determine the root location of your PHP application. This function is similar to file (), except that filegetcontents () returns the file in a string, starting at the specified offset up to length bytes. The URI used to access this page for instance, '/index.html'. The FILE constant contains the full path and filename of the current (i.e. You can then upload the file to the directory where you want to place the. This is useful for pages which need to point to themselves. Copy the code and paste it into a file called fullpath.php. Below is a small PHP script that prints the full path to the directory it is placed in. SERVER'PHPSELF' - gives the route of the current file (after the domain name) /this/is/a/url SERVER'SERVERNAME' - gives the domain name SERVER'HTTPREFERER' - gives the correct HTTP(S) protocol and domain name.
