If you want to store 3 values is no problem. When it goes upto 100 or 200 then there may be a problem raised. The best solution to avoid this is to use an Array.
Array is an single variable that holds multiple values. In an array you can store the related values into a single variable.
If you have a list of items like (banana,apple,orange), then storing the fruits in a single variable could look like this:
In PHP, there are three kinds of arrays. They are
Numeric arrays - An array with numeric index
Associative array - An array where each ID key is associated with a value.
Multi dimensional array - An array containing one or more arrays.
In PHP, there are 2 ways to create a numeric array
1. Index are automatically assigned. Example
2. Assign the indexes manually. Example
In an associative array each ID key is associated with a value.
When storing data about specific named values, a numerical array is not always the best way to do it.
With associative arrays we can use the values as keys and assign values to them.
There are 2 ways to create an associative array
$age = array("Kennedy"=>32, "Lincoln"=>30, "Bush"=>34);
2.,ID keys are used in a script
$ages['Kennedy'] = "32";
$ages['Lincoln'] = "30";
$ages['Bush'] = "34";
echo "Kennedy is " . $ages['kennedy'] . " years old.";
Kennedy is 32 years old.
