Listing 4–4 will load the .dll file as well as set two APC settings, which we will review in greater detail later in this chapter. The extension setting must contain the full path to the .dll file if it is not present in the PHP ext directory.
To verify the installation, create a php info PHP script containing the code shown in Listing 4–3 and load the page using a web browser. If APC was installed correctly, you should see an entry similar to Figure 4–4.
