How can you check if a variable is a string or an integer in PHP?
Integers - The "is_int()" function can be used to check if a variable is has an integer for its value. ---- is_int($variable); // Returns true if $variable is an integer - otherwise false ---- Numeric Strings - Numeric strings are strings with numbers (or things that count as numbers) in them. Numeric-string variables are not integer variables. Numeric-string variables are passed on through forms, instead of integer variables - if you were wondering. Check form values using string formats, and not integer formats. The "is_numeric()" function can be used to check if a variable is a string with numbers - and only numbers - in it (except things that add up to be numbers). ---- is_numeric($variable); // Returns true if $variable is a string, and only contains numbers (broadly speaking) - false otherwise ---- Strings - String values are just text, basically. String variables can contain integers, but that does not make it an integer-type variable - it makes it a numeric string variable. The "is_string" function can be used to check if a variable contains the value of a string. ---- is_string($variable); // Returns true if $variable is a string - false otherwise
