| + | ====== Debug PHP with xdebug ===== | ||
| + | Refer: http:// | ||
| + | ===== xdebug architecture ===== | ||
| + | ==== PHP Cli Debugging ===== | ||
| + | {{: | ||
| + | The PHP extension php_xdebug.dll seamlessly installs code to provide interpreter control and communication between a client (Notepad++ with DBGp plugin installed in the IDE) and the PHP interpreter over port 9000. Effectively php_xdebug.dll includes a mini server to provide communication with a client.\\ | ||
| + | Sequence of events | ||
| + | * Step A) Run Notepad++. | ||
| + | * Step B) Start Notepad++' | ||
| + | * (listens on port 9000) | ||
| + | * Step C) Run script from Notepad++ (Executes PHP interpreter). | ||
| + | * Step D) Interpreter loads configuration file and loads extensions (php_xdebug.dll) | ||
| + | * Step E) XDebug establishes contact with client. | ||
| + | * Step F) Script is loaded and run. | ||
| + | * Step G) Script execution (debugging) is controlled by client. | ||
| + | Notes: | ||
| + | * Note 1: Debugging is initiated as soon as the interpreter loads XDebug. | ||
| + | * Note 2: If the script is initiated from an external source (for example, a batch file), XDebug determines if the script (F) is displayed in Notepad++. If not, it is downloaded. | ||
| + | |||
| + | * Note 3: If XDebug starts debugging a new page, that page is downloaded if not already displayed in Notepad++. | ||
| + | ==== Web page Debugging ===== | ||
| + | {{: | ||
| + | The second server is created using a PHP extension (php_xdebug.dll). It seamlessly installs code to provide communication between Apache and a client (Notepad++ with DBGpplugin installed) over port 9000. In addition, code is installed to monitor browser requests arriving on the standard Apache port 80.\\ | ||
| + | Sequence of events(Assumes Uniform Server running (Apache server running)) | ||
| + | * Step A) Start Notepad++. | ||
| + | * Step B) Notepad++' | ||
| + | * Step C) In a browser, enter address of PHP page to be debugged. | ||
| + | * Step D) Browser requests this page from Apache server over port 80 | ||
| + | * Step E) Apache runs the PHP interpreter | ||
| + | * Step F) PHP interpreter runs its extensions including the XDebug module. | ||
| + | |||
| + | * Step G) XDebug module starts remote debugging. | ||
| + | * Step H) XDebug connects to debugging client over port 9000 | ||
| + | |||
| + | * Step I) User uses client for debugging. Commands and data are sent over port 9000 | ||
| + | * Step J) Client can instruct XDebug to execute one or more php statements. Your PHP code is executed; this may output data over http Port (80) to web browser. | ||
| + | |||
| + | * Step K) When all your PHP code has been executed, XDdebug disconnects from client. | ||
| + | * Step L) Followed by Apache closing connection to browser. | ||
