Integers are whole numbers such as 1 and 2. This also includes negative whole numbers such as -3 and -4. PHP uses integers for a variety of applications, such as mathematical calculations like multiplication and addition. Integers can also be used to set the range of how certain functions work in addition to increasing or decreasing another integer. "Numbers part one: Integers" introduces elementary working knowledge of how integers work in PHP and MySQL.
