PHP IntlChar::isbase() function is an inbuilt function in PHP that is used to check whether the given input data is a base character or not. If the specified code point is a base character then it returns TRUE for general categories “L” (Letters), “N” (numbers), “Mc” (spacing combining marks), and “Me” (enclosing marks).

Syntax:

bool IntlChar::isbase( $codepoint )

Parameters: This function accepts a single parameter $codepoint which is mandatory. The input parameter is an integer or character, which is encoded as a UTF-8 string.

Return Value: If $codepoint is the base character then it returns TRUE, otherwise return FALSE.

Examples:

Input :(IntlChar::isbase("D"))
Output : bool(true)

Input : (IntlChar::isbase("*"))
Output : bool(false)

Input :(IntlChar::isbase("9"));
Output :bool(true)
