How to install and configure Xdebug under Linux

Xdebug Introduction

Xdebug is an open source PHP program debugger (a debug tool) that can be used to track, debug, and analyze the health of PHP programs.

Xdebug Installation

First let PHP error display, only need to modify the php.ini of the 2 instructions, the displayerrors and Htmlerrors are set to ON, as shown below

Html_errors = Ondisplay_errors = On

Of course if you need to see more information, such as printing the call stack, you need to install Xdebug, which is especially helpful for more complex code systems.

Xdebug is a module of PHP, need to compile the installation, I use LNMP installed php,php is installed by default to/usr/local/php, and then do a hard link to/usr/bin

Compile Xdebug First

Download Xdebug wget http://www.xdebug.org/files/xdebug-2.2.3.tgz

and start compiling.

Tar xzf xdebug-2.2.3.tgzcd xdebug-2.2.3/usr/bin/phpize./configure--with-php-config=/usr/local/php/bin/ Php-configmake make test I have a problem here is  to open the Proc_openmake install in the php.ini file  

Compile finish Next Modify the php.ini configuration, you can first go to your PHP installation path under the Lib library directory to see if the xdebug.so file is generated, if it is generated, add the following to the php.ini file

no-debug-non-zts-20090626 this folder name and PHP version are one by one corresponding

zend_extension= "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so" xdebug.default_enable = Onxdebug.show_exception_trace = Onxdebug.show_local_vars = 1xdebug.max_nesting_level = 50xdebug.var_display_max_  depth = 6xdebug.dump_once = Onxdebug.dump_globals = onxdebug.dump_undefined = Onxdebug.dump.REQUEST = *xdebug.cli_color = 2

Restart PHP-FPM, write the wrong PHP code, refresh the browser, you can see the error prompt.
