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)
Below examples illustrate the IntlChar::isbase() Function in PHP:

<?php // PHP code to illustrate IntlChar::isbase() // Function // Input data is character type var_dump(IntlChar::isbase( "D" ));
// Input data is string type var_dump(IntlChar::isbase( "Geeksforgeeks" ));
// Input data is integer type var_dump(IntlChar::isbase( "234" ));
// Input data is special character type var_dump(IntlChar::isbase( "*" ));
?> |
Output:
bool(true) NULL NULL bool(false)
Example 2:
<?php //PHP code to illustrate IntlChar::isbase() // Declare an array $arr $arr = array ( "4" , "20001111" , "^" , " " , "*" , "GeeksforGeeks" );
// Loop run for every array element foreach ( $arr as $val ){
// Check each element as code point data
var_dump(IntlChar::isbase( $val ));
