PHP has over 1,000 built-in functions that can be called directly from within a script. These functions are pre-defined and included within the core PHP language. They can be used without any special requirements or additional installation. Some examples of built-in functions include: String functions: Manipulate strings. Examples include: strlen(): Calculates string length strtoupper(): Converts strings to uppercase substr(): Extracts a portion of a string Mathematical functions: Perform mathematical operations Date and Time Manipulation: Functions for working with dates and times, such as date() to format and display current date and time Array Manipulation: Functions that offer various ways to manipulate arrays, such as count() to get the length of an array In addition to built-in functions, PHP also allows users to create their own custom functions. To create a user-defined function, you can: Start with the keyword function Follow with the name of the function Give the function a name that reflects what the function does To call a function, you can: Write its name followed by parentheses () For example, `function myMessage() ( echo `Hello world! ''; ) myMessage(); All functions in PHP return a value, even if you don't explicitly cause them to. You can specify the return value of your function by using the return keyword. Show less
