Question

In PHP 5 how many of the following functions are part of the PHP core?

Answer 1

Without a specific list of functions, it is impossible to determine how many are part of the PHP 5 core. PHP 5 includes many built-in functions that are part of the core and others available through extensions.

Step-by-step explanation:

The question pertains to the PHP 5 programming language and is inquiring about the number of specified functions that are included in the PHP core. Since the list of functions is not provided in the question, it is impossible to answer it accurately. In PHP 5, many functions are part of the core language, and others can be found in various extensions. If you have a specific list of functions, it would be possible to check each one against the PHP documentation to determine if it is a core function or part of an extension.
