The PHP language has over 1000 built-in functions. The exact number can vary between different versions of PHP, and it can also change as new functions are added in new versions and outdated functions are deprecated and removed.
These functions cover a wide range of functionalities, including string manipulation, array manipulation, file handling, database interaction, date and time processing, session handling, and more.
Remember that in addition to these built-in functions, developers can also define their own custom functions, and many PHP frameworks and libraries provide additional functions.
