ZendDebugger php 5.3 Centos 5

Just a few questions regarding php 5.3, php.ini and zend debugger.

1) I’m about to install the zenddebugger.so on my centos 5.3 with php 5.3. Where do I install it? What folder location?
I ended up installing the ZendDebugger.so at /usr/local/lib/php/extensions/
I added this to my php.ini file at the end of the file:


2) I compiled php 5.3 but I’m wondering where is the executable?
The PHP CLI bin is located at:

3) I found the php.ini file at /usr/local/lib. Is this the default php.ini that centos 5.3 uses?
I believe it is since when I compiled php I didn’t add in the option ./configure prefix=

4) I know that there can be different php versions that apache can use. How do I ensure that the apache uses the correct php version if I have multiple php versions installed?
This works in my httpd.conf on my windows vista:
SetEnv PHPRC “C:/Program Files/PHP/”

I haven’t tested this on my Centos machine though.

I ran:
find / -name ‘php.ini’

and another php.ini is installed at:

the other is located as mentioned previously at:

I’m not certain which one is apache using. I installed my custom apache at:


This is the output from my php source install just fyi:

You may want to add: /usr/local/lib/php to your php.ini include_path
/home/vkimura/php-5.3.1/build/shtool install -c ext/phar/phar.phar /usr/local/bin
ln -s -f /usr/local/bin/phar.phar /usr/local/bin/phar

Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR’
flag during linking and do at least one of the following:
– add LIBDIR to the `LD_LIBRARY_PATH’ environment variable
during execution
– add LIBDIR to the `LD_RUN_PATH’ environment variable
during linking
– use the `-Wl,–rpath -Wl,LIBDIR’ linker flag
– have your system administrator add LIBDIR to `/etc/ld.so.conf’

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
