An array is a special type of variable. – can hold multiple data values A sequential array keeps track of these data items by using sequential numbers – (., item 0, item 1, item 2, and so on) on) A nonsequential array or associative array keeps track of these data items by using character strings – (., item meat, item poultry, item dairy, and so on) on) Include a flexible number of list items. Examine each item more concisely. Using Loops to Repeat Statements Use special array operators and functions. 5 Content 6 . Creating Sequential Arrays 1. Benefits of arrays 2. Sequential arrays 3. Non-sequential arrays Non4. Multidimensional lists Use the array() function to create an array You could also create an array with y numerical data – $grades = array(66, 75, 85, 80); 7 8 2 Another way to create an array . Referencing Sequential Array Items You can also create an array by making i di id l value assignments ki individual l i t into the array variable name. To reference individual array items, use an array name and index pair For example, $students[] = 'Johnson'; Johnson' Indices are referenced sequentially: $students[] = 'Jones'; Jones' – $ $names = array('Denise', 'Ch i t h ' 'M tth ' ('D i ' 'Christopher', 'Matthew', 'Bryant'); 'Bryant'); – print ("$names[0], $names[1], $names[2], $names[3]"); $students[] = .
