It allows external document generators like phpDocumentor, which is the de facto standard implementation, [1] to generate documentation of APIs and helps some IDEs such as Zend Studio, NetBeans, JetBrains PhpStorm, ActiveState Komodo Edit and IDE, PHPEdit and Aptana Studio to interpret variable types and other ambiguities in the loosely typed ...
A directory traversal (or path traversal) attack exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing "traverse to parent directory" are passed through to the operating system's file system API. An affected application can be exploited to gain unauthorized access to the file ...

PHP has hundreds of base functions and thousands more from extensions. Prior to PHP version 5.3.0, functions are not first-class functions and can only be referenced by their name, whereas PHP 5.3.0 introduces closures. [35] User-defined functions can be created at any time and without being prototyped. [35]
For example: What the user may consider as valid input may contain token characters or strings that have been reserved by the developer to have special meaning (such as the ampersand or quotation marks). The user may submit a malformed file as input that is handled properly in one application but is toxic to the receiving system.
A valid file URI must therefore begin with either file:/path (no hostname), file:///path (empty hostname), or file://hostname/path. file://path (i.e. two slashes, without a hostname) is never correct, but is often used. Further slashes in path separate directory names in a hierarchical system of directories and subdirectories. In this usage ...
UNC names (any path starting with \\?\) do not support slashes. [4] The following examples show MS-DOS/Windows-style paths, with backslashes used to match the most common syntax: A:\Temp\File.txt This path points to a file with the name File.txt, located in the directory Temp, which in turn is located in the root directory of the drive A:.
VFAT, a variant of FAT with an extended directory format, was introduced in Windows 95 and Windows NT 3.5. It allowed mixed-case Unicode long filenames (LFNs) in addition to classic 8.3 names by using multiple 32-byte directory entry records for long filenames (in such a way that old 8.3 system software will only recognize one as the valid directory entry).
