How can i trace php code?
PHP applications are not always web applications. Various command line tools, daemons, message queue processing applications and other types of applications typically run in the PHP CLI. There are several ways to start a PHP CLI debugging session. You can start it from within PhpStorm and make it start the script and attach the debugger to it. Alternatively, you can let PhpStorm listen for incoming debugger connections
and start the script outside the IDE. We'll take a look at both options. Before you start debugging, make sure that you have a debugging engine installed and configured properly. PhpStorm supports debugging with two most popular tools: Xdebug and
Zend Debugger. These tools cannot be used simultaneously because they block each other. To avoid this problem, you need to update the corresponding sections in the php.ini file as described in Configure Xdebug and
Configure Zend Debugger. Open the active php.ini file in the editor: In the Settings/Preferences dialog
(Ctrl+Alt+S), click PHP. On the
PHP page that opens, click In the CLI Interpreters dialog that opens, the Configuration file read-only field shows the path to the active php.ini file. Click Open in Editor. Start a debugging session from PhpStormTo start debugging a PHP CLI script from within PhpStorm, perform the following steps. Create a Run/Debug ConfigurationPhpStorm uses Run/Debug configurations to execute a script from within the IDE. A configuration can define additional arguments for the PHP interpreter as well as launch other commands prior to starting our script. We will need a Run/Debug configuration to start the debugger from within PhpStorm. Create a Run/Debug configuration for a PHP script manually
Generate a Run/Debug configuration for a PHP script
Launch the DebuggerBefore launching the debugger, make sure that either a breakpoint is set or the Break at first line in PHP scripts option is enabled on the Debug page of the Settings/Preferences dialog Ctrl+Alt+S.
Switch between configured PHP interpreters on the fly
The selected interpreter will be set as the default project interpreter on the PHP page of the Settings/Preferences dialog (Ctrl+Alt+S). This will also affect the run/debug configurations, test frameworks', and quality tools' configurations that are set to use the default project interpreter. Start a debugging session from the command lineBefore you start a debugging session with PhpStorm when running CLI scripts, make sure that any of the following requirements is met:
Listening for incoming debugger connectionsIn PhpStorm, enable listening to incoming debug connections by either clicking on the toolbar or selecting . This will ensure PhpStorm reacts when a debugging session is started and opens the debug tool window automatically. Before launching the script, make sure that either a breakpoint is set or the Break at first line in PHP scripts option is enabled on the Debug page of the Settings/Preferences dialog Ctrl+Alt+S. Start the script with debugger optionsSince we'll be starting the script from the command line, we will have to make sure it is started with the required settings to enable the debugger. Starting the script with XdebugXdebug has various configuration options which we can use to let the PHP interpreter reach out to PhpStorm. These parameters have to be passed to the PHP interpreter using the Start the script with debugging using PHP command-line switches
Start the script with debugging using an environment variable
Starting the script with Zend DebuggerZend Debugger has various configuration options which we can use to let the PHP interpreter reach out to PhpStorm. These parameters have to be passed to the PHP interpreter using an environment variable. Start the script with debugging
Optionally, to tell PhpStorm which path mapping configuration should be used for a connection from a certain machine, the value of the set PHP_IDE_CONFIG=serverName=SomeName export PHP_IDE_CONFIG="serverName=SomeName" If this environment variable is not set, you'll be prompted to specify path mappings manually once IDE detects an incoming Xdebug connection. DebugOnce the script is started, PhpStorm will open the Debug tool window and break at the first breakpoint that was set in the script. You can now continue debugging a PHP CLI script as described in Examining a Suspended Program. If the script that is being debugged is not a part of the project that's open in PhpStorm, the IDE will still open the script in the editor and pause execution at the first statement. This makes it possible to quickly debug any PHP CLI script, even if there is no PhpStorm project for it yet.

It is capable of reporting function-level call counts and inclusive and exclusive wall time, CPU time and memory usage. Xhprof is very useful for performance tracing on local and production environment but not for debugging other problems.
