PHP Arrays

An array stores multiple values in one single variable.

Types of Arrays in PHP:

  • Indexed arrays - Arrays with a numeric index
  • Associative arrays - Arrays with named keys
  • Multidimensional arrays - Arrays containing one or more arrays

Use the count() function to return the length (the number of elements) of an array.
