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]
Node.js programs are invoked by running the interpreter node interpreter with a given file, so the first two arguments will be node and the name of the JavaScript source file. It is often useful to extract the rest of the arguments by slicing a sub-array from process.argv. [11]
Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content or dynamic images used on websites or elsewhere. [284] It can also be used for command-line scripting and client-side graphical user interface (GUI) applications.
PHPDoc is an adaptation of Javadoc format for the PHP programming language.It is still an informal standard for commenting PHP code, but it is in the process of being formalized. [1]
The diff command is invoked from the command line, passing it the names of two files: diff original new. The output of the command represents the changes required to transform the original file into the new file. If original and new are directories, then diff will be run on each file that exists in both directories.
The included document can itself be another SSI-enabled file. The file or virtual parameters specify the file (HTML page, text file, script, etc.) to be included. NCSA HTTPd did not support CGI via include, [2] but later Apache HTTPd does. [7] If the process does not have access to read the file or execute the script, the include will fail.
Rather than using the ZIP file format the simpler tar format was used, and the first PHAR was created using the tar command line utility [1] as a proof of concept. On June 14, 2004 [ 2 ] the initial PHP_Archive package was proposed to PEAR and on December 13, 2004 it was accepted unanimously.
In computing, a here document (here-document, here-text, heredoc, hereis, here-string or here-script) is a file literal or input stream literal: it is a section of a source code file that is treated as if it were a separate file.
