PHP Arrays

Submitted by admin on Tuesday, November 19, 2013 - 12:13.

An array is the same as variable except that it can store multiple values using an index key. Here’s an example:

<?php
$names = array("John", "Peter", "Matthew", "Andrew")
 
echo "The following are biblical name: " . names[0] . ", " . names[1] . ", " . names[2] . ", " . names[3] . ".";
?>

You can also directly assign a value into an array with its index key, example:

<?php
$names[0] = "John";
$names[1] = "Peter";
$names[2] = "Matthew";
$names[3] = "Andrew";
 
echo "The following are biblical name: " . names[0] . ", " . names[1] . ", " . names[2] . ", " . names[3] . ".";
?>

The above example is using number as an index key. You can also use named key to identify an array easily. Consider the following example:

<?php
$name["John"] = 35;
$name["Peter"] = 28;
$name["Matthew"] = 31;
$name["Andrew"] = 34;
 
echo "John’s age is: " . $name["John"];
?>

An associative array is very useful if you want to access your table’s record using a field name. Example:

<?php
echo $table["name"];
echo $table["address"];
?>
