How do I set PHP include_path?
There are at least 2 ways you can set your PHP include_path.
- Edit your
/etc/php.ini file. Inside that file is a directive section for "Paths
and Directories." By default it is set to ".:/usr/local/lib/php". You
can change that value to whatever you like or add to (or eliminate) the
default like this:
- include_path = .:/usr/local/lib/php:./include
above must be entered all on one line, with no linebreaks. The above
will cause php scripts to search for a directory named "include", and
will look for it under the current directory of the running script in
addition to the default, which is to first search the current directory
and then search the /usr/local/lib/php directory (which is a system
directory that is not writeable by you and is reserved for things like PEAR).
format of the include_path variable is a list of directories separated
with a colon. A "." (a period) in the include path means the current
directory, and allows for relative includes. More information is
- Use the function ini_set().
For example if you wanted to set your PHP include_path to
".:../:./include:../include" then you would do this in your PHP code:
ini_set("include_path", ".:../:./include:../include");You can also use ini_set() to affect other PHP settings like
