A.23.12. PHP_Fork

Repository: - License: PHP License -

PHP_Fork class. Wrapper around the pcntl_fork() stuff with a API set like Java language

A.23.12.1 Description

PHP_Fork class. Wrapper around the pcntl_fork() stuff with a API set like Java language. Practical usage is done by extending this class, and re-defining the run() method. [see basic example]

This way PHP developers can enclose logic into a class that extends PHP_Fork, then execute the start() method that forks a child process. Communications with the forked process is ensured by using a Shared Memory Segment; by using a user-defined signal and this shared memory developers can access to child process methods that returns a serializable variable.

The shared variable space can be accessed with the tho methods:

  • void setVariable($name, $value)

  • mixed getVariable($name)

$name must be a valid PHP variable name;

$value must be a variable or a serializable object.

Resources (db connections, streams, etc.) cannot be serialized and so they're not correctly handled.

Requires PHP build with --enable-cli --with-pcntl --enable-shmop.

Only runs on *NIX systems, because Windows lacks of the pcntl ext.

@example simple_controller.php shows how to attach a controller to started pseudo-threads.

@example exec_methods.php shows a workaround to execute methods into the child process.

@example passing_vars.php shows variable exchange between the parent process and started pseudo-threads.

@example basic.php a basic example, only two pseudo-threads that increment a counter simultaneously.

A.23.13. PHP_Parser

Repository: PEAR - License: PHP License - By Greg Beaver (lead) - Alan Knowles (developer)

A PHP Grammar Parser

A.23.13.1 Description

PHP_Parser is a source code analysis tool based around a real Parser generated by phpJay. The parser uses the same EBNF source that PHP uses to parse itself, and it therefore as robust as PHP itself. This version has full support for parsing out every re-usable element in PHP 5 as of beta 1:

  • classes

  • abstract classes

  • inheritance, implements

  • interfaces

  • methods

  • exception parsing directly from source

  • static variables declared

  • global and superglobal ($_GET) variables used

and declared

  • variables

  • constants

  • functions (same information as methods)

  • defines

  • global variables (with help of the Tokenizer Lexer)

  • superglobal variables used in global code

  • include statements

The output can be customized to return an array, return objects of user-specified classes, and can also be customized to publish each element as it is parsed, allowing hooks into parsing to catch information.

A.23.14. python

Repository: PECL - License: PHP - By Jon Parise (lead)

Embedded Python

A.23.14.1 Description

This extension allows the Python interpreter to be embedded inside of PHP, allowing for the instantiate and manipulation of Python objects from within PHP.

A.23.16. Var_Dump

Repository: - License: PHP License -

Provides methods for dumping structured information about a variable.

A.23.16.1 Description

The Var_Dump class is a wrapper for the var_dump function.

The var_dump function displays structured information about expressions that includes its type and value. Arrays are explored recursively with values indented to show structure.

The Var_Dump class captures the output of the var_dump function, by using output control functions, and then uses external renderer classes for displaying the result in various graphical ways :

  • Simple text,

  • (X)HTML text,

  • (X)HTML table,

  • XML,

  • ...

A.23.17. vld

Repository: PECL - License: BSD style By: Derick Rethans (lead)

A.23.18. Xdebug

Repository: PECL - License: BSD style By: Derick Rethans (lead)

Provides functions for function traces and profiling
