12.4. CLI Environment

PEAR lets you include command-line scripts in a package. However, when doing so, you will quickly run into configuration problems like, “Which include_path should I use here” or “What is the full path of the PHP executable that should be used?” This information may be specified by users in a set of environment variables, as shown in Table 12.1.
