![]() Consider the following two scripts: frontend.php and backend.php. However, this will only work for the first script we hit. For our frontend script, we'll do this from the browser using the IntelliJ IDEA bookmarklets or a Browser Debugging Extension.īoth debugging engines can start a debugging session on-demand by passing in a request variable ( XDEBUG_SESSION_START=session_name for Xdebug, start_debug=1 for Zend Debugger), which is what the bookmarklets and browser extensions do. While possible, it's good practice to not do this for every request being made but only for those where debugging is desired. The way Xdebug and Zend Debugger work is that they make a connection from the PHP interpreter to the IDE. Click Open in Editor.Įnsure a debugger session is started for secondary requests This plugin for IntelliJ IDEA Ultimate helps to get an overview of coupling and cohesion in java projects in two different contexts: References of. In the CLI Interpreters dialog that opens, the Configuration file read-only field shows the path to the active php.ini file. On the PHP reference page that opens, click next to the CLI Interpreter field. In the Settings dialog ( Control+Alt+S), click PHP under Languages & Frameworks. Open the active php.ini file in the editor: ![]() 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. These tools cannot be used simultaneously because they block each other. IntelliJ IDEA supports debugging with two most popular tools: Xdebug and Zend Debugger. Open the Marketplace tab, find the PHP plugin, and click Install (restart the IDE if prompted).īefore you start debugging, make sure that you have a debugging engine installed and configured properly. Press Control+Alt+S to open the IDE settings and then select Plugins. The PHP plugin is available only in IntelliJ IDEA Ultimate. This functionality relies on the PHP plugin, which you need to install and enable. This tutorial describes several ways to step from front-end code into back-end code and debug them simultaneously. Often, developers work on both sides of such application at the same time. This covered Simple debugging in IntelliJ IDEA and We’ll introduce Remote debugging in IntelliJ IDEA in next coming part.When building web applications with multiple tiers, you can have frontend PHP code calling into backend PHP code. There is also a button Mute Breakpoints button in this window. You can view all breakpoints on clicking View BreakPoints button in debugger window and also can remove or add breakpoints here. You can evaluate any expression on clicking Evaluate Expression button in debugger window.Įnter any expression which you want to evaluate then click on Evaluate button. Select examining variable then click on Add to Watches button in Watches window, output get displayed. You can press F8 to step to the next statement and f9 to step to the next breakpoint.Īs you step through your application, the corresponding information appears in the debugger window. Such a breakpoint is marked with a blue stripe. Select run menu and click on debug, now your application start in debug mode.Īfter starting application your program execution suspends when the first breakpoint is hit. This is most easy – just click the left gutter at the line you want the script to suspend. Part 3- Debug JavaScript in IntelliJ IDEAįollowing are some steps to run your grails application in debug mode. Part 2- Remote debugging in IntelliJ IDEA Part 1- Simple Debugging in IntelliJ IDEA I have decide to cover ‘Debugging in IntelliJ IDEA’ in three part blog series as listed below If we run app in debug mode, for evaluating any expressions, we just set the breakpoints and evaluate the expressions with no need to reload the app, there by increasing our productivity. May be they just need to change the mindset to take advantage of this helpful feature. As per my observation, there is no performance difference between run-app and debug app. Many people try avoiding using this awesome feature just because, either, they don’t want to leave the old habit of using printlns or they complain about the performance issue, and bla bla bla. IntelliJ IDEA provides a handy debugger for grails, which simplifies debugging.
