I am not sure about that; it may be possible to set LD_LIBRARY_PATH just for 
the php(1) invocation.

Apropos, there are several ways to run php(1) without the system’s php.ini:

-c  specifies the php.ini file to use; you can write a temporary php.ini to
    ${TMPDIR:-/tmp} (using mktemp(1)) when invoking php(1) in case named
    pipes, with which you can generate a php.ini on the fly (see example
    below), are not supported;

-n  specifies that no php.ini file is used, falling back to the compiled 
    defaults; try e.g. “php -n -r 'phpinfo(INFO_GENERAL);'”

-d  allows to set php.ini directives on the command line, so with “-n”
    you do not need the workaround with “-c”.

Example:

$ ls Application.php
ls: cannot access Application.php: No such file or directory

$ php -c <(echo 'include_path = /LCARS/scripts/php') \
      -r 'require_once "Application.php";'
[no error]

  or

$ php -n -d include_path=/LCARS/scripts/php \
         -r 'require_once "Application.php";'
[no error]
