Ignore my previous note, I forgot to add in where to use the PECL command to install phplua.Installation on Ubuntu 14.04"*.*" means version numberPackages to install (sudo apt-get install):Install php5Install php-pearInstall php5-devInstall lua*.*Install liblua*.*Create soft link of /usr/include/lua TO /usr/include/lua*.*:sudo ln -s /usr/include/lua*.*/ /usr/include/luaFind liblua*.*.so and liblua*.*.a files in /usr/lib.If they don't exist, they could be in /usr/lib/x86_64-linux-gnu or /usr/lib/i386-linux-gnu depending on OS.Copy them from that directory into /usr/lib as liblua.so and liblua.a (WITHOUT VERSION NUMBER).Example:sudo cp /usr/lib/x86_64-linux-gnu/liblua5.2.a /usr/lib/liblua.aNow execute the following command (1.1.0 is the version at the time of writing this):sudo pecl install lua-1.1.0Add extension=lua.so to php.ini file (could be /etc/php5/(cli/apache)/php.ini)Hope this helps.

Simple guide to install phplua on CentOS 6.3:Run these commands in terminal as root:$yum install php-pear php-devel gcc lua-devel lua-static$mkdir /usr/include/lua$ln -s /usr/include/lua.h /usr/include/lua/lua.h$pecl install lua-1.0.0Then edit /etc/php.ini and add the following line below the similar ones:extension=lua.soFinally restart your web server and you should be all done!I spent days googling around, trying and failing and gathering up what needs to be installed when you just have apache2 and php5 installed and working.Thus there is this bug preventing pecl from finding lua.h, which is fixed by the symlink created above. The bug is already submitted:https://bugs.php.net/bug.php?id=60641Hope this info helps some body else too!
