installed Xdebug on a Fedora 17 OS

I installed Xdebug on a Fedora 17 OS in order to use it with netbeans 7.3.1 It took me some time so I share with you how did I managed to have it working:

Install Xdebug:

sudo yum install php-pecl-xdebug

Add this lines to php.ini at the end of the file:

sudo vi /etc/php.ini

zend_extension=/usr/lib64/php/modules/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000

Add the same lines to xdebug.ini file:

sudo vi /etc/php-zts.d/xdebug.ini

xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000

Allow port for Xdebug

sudo semanage port -a -t http_port_t -p tcp 9000

Now find your netbeans.conf file in your system:

sudo find / -name netbeans.conf

Now, open up the file and add the text "-J-Dorg.netbeans.modules.php.dbgp.level=400" in netbeans_default_options so that the line looks somewhat like this:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Dsun.awt.disableMixing=true -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J-Dorg.netbeans.modules.php.dbgp.level=400"

Restart both NetBeans IDE and apache:

sudo service httpd restart

if not working then use

SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp

You messed up with /tmp permissions. To fix:

chown root:root /tmp (root:root is mysql username and password which you used)

chmod 1777 /tmp 

/etc/init.d/mysqld restart (mysqld service restart)

    $query      = "LOAD DATA INFILE '$backupFile' INTO TABLE $tableName";
    $result = mysql_query($query);

    echo "backup restore complete";

    mysql_close($link);
    $link = null;

X-Debug in php 5.4.17

I installed Xdebug on a Fedora 17 OS in order to use it with netbeans 7.3.1 It took me some time so I share with you how did I managed to have it working:

Install Xdebug:

sudo yum install php-pecl-xdebug

Add this lines to php.ini at the end of the file:

sudo vi /etc/php.ini

zend_extension=/usr/lib64/php/modules/xdebug.so

xdebug.remote_enable=1

xdebug.remote_handler=dbgp

xdebug.remote_mode=req

xdebug.remote_host=127.0.0.1

xdebug.remote_port=9000

Add the same lines to xdebug.ini file:

sudo vi /etc/php-zts.d/xdebug.ini

xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000

Allow port for Xdebug

sudo semanage port -a -t http_port_t -p tcp 9000

Now find your netbeans.conf file in your system:

sudo find / -name netbeans.conf

Now, open up the file and add the text "-J-Dorg.netbeans.modules.php.dbgp.level=400" in netbeans_default_options so that the line looks somewhat like this:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Dsun.awt.disableMixing=true -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J-Dorg.netbeans.modules.php.dbgp.level=400"

Restart both NetBeans IDE and apache:

sudo service httpd restart

if not working then use

xdebug.remote_host=127.0.0.1 to ip address of computer
