The VCx marker tells with which compiler the extension was built, and Non-thread-safe whether ZTS was disabled. Those qualifiers need to match the PHP version you're using." You need to get answers on few simple questions, firstly 1. there are more ways to find this out either $ php -v PHP 5.2.6-3ubuntu4.1 with Suhosin-Patch 0.9.6.2 (cli) (built: Apr 23 2009 ) Copyright (c) 1997-2008 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies with Xdebug v2.0.3, Copyright (c) 2002-2007, by Derick Rethans you should get output like below after running it in browser Clearly my version of php is 5.2.6-3 2. non-threaded use of PHP" for example the CLI, CGI or Apache 1.3 module threaded usage of PHP, for example the Apache 2 work MPM or the the ISAPI module either run on Linux $ apache2 -V Server version: Apache/2.2.11 (Ubuntu) Server built: Jun 11 2009 Server's Module Magic Number: 200511 Server loaded: APR 1.2.12, APR-Util 1.2.12 Compiled using: APR 1.2.12, APR-Util 1.2.12 Architecture: 64-bit ==Server MPM: Prefork!!! Well, this is probably the easiest way to install XDebug but if it doesn't work then you are in trouble.Compiling your own version of xdebug is actually easier than you would think and you don't even need to use the command line so much.You can use this option with Net Beans but you have to customize your environment.A discussion of ways and means of using xdebug_file_link_format with Net Beans is available on The PHP Users Forum. Xdebug 2.1.beta2 (or beta3 when you checkout sources) is current release that correctly works with php5.3.x (at the time being).If Netbeans is failing to connect, chances are it's a problem with x Debug and nothing to do with Netbeans.
3: Get xdebug's debugclient working on localhost first, then add Netbeans.I started with a fresh Snow Leopard installation that comes with prebuilt apache and php.zend_extension = /usr/lib/php/extensions/no-debug-non-zts-20090626/xdebug.remote_enable=on xdebug.remote_log="/var/log/xdebug.log" xdebug.remote_host=localhost xdebug.remote_handler=dbgp xdebug.remote_port=9000 PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.2.9-1/ext/php_xdebug-2.0.4-5.3.0-vc9.dll' - The application has failed to start because its side-by-side configuration is incorrect.composer require intervention/image Using version ^2.3 for intervention/image ./has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages.Problem 1 - intervention/image 2.3.6 requires ext-fileinfo * - satisfiable by intervention/image[2.3.0, 2.3.1, 2.3.2, 2.3.3, 2.3.4, 2.3.5, 2.3.6].Do not paste the raw HTML (from view-source) into the form. If you use Windows you most probably need thread safe version . Go to Xdebug download page and download appropriate file. Well, building from sources can be tedious but building xdebug is pretty easy process. You may want to see "installation how to" on in particular.
