What is the result of the following code snippet? $a = 10; echo gettype($a);

The gettype() function returns the type of the variable as a string. For an integer value, it returns the string 'integer'. While 'int' is the type name used in type hinting, gettype() specifically returns 'integer'.

Key points

gettype() returns a string representation
Integer values return 'integer'
Type names in code differ from gettype() output
