Copy Code code as follows:
$full _name = Array ();
$full _name["Roger"] = "Waters";
$full _name["Richard"] = "Wright";
$full _name["Nick"] = "Mason";
$full _name["David"] = "Gilmour";
To sort this array, you just use the Assort () function. This involves is the complex than typing the word asort, followed by round brackets. In between the round brackets, type in the name of your associative array:
Copy Code code as follows:
The letter "A" tells PHP to that the array is a associative one. (If you don ' t have the "a" before "sort", your key names'll turn in to numbers!). The "A" also tells PHP to sort by the Value, and isn't by the key. In our script above, the surnames'll be sorted. If you want to sort using the Key, then your can use Ksort () instead.
If you are have a Scalar array (numbers as Keys), then you leave the "a" off. Like this:
Copy Code code as follows:
$numbers = Array ();
$numbers []= "2";
$numbers []= "8";
$numbers []= "10";
$numbers []= "6";
Sort ($numbers);
Print $numbers [0];
Print $numbers [1];
Print $numbers [2];
Print $numbers [3];
The numbers are then sorted from lowest to highest. If you are want to sort in reverse order then you need the following:
Rsort () –sorts a Scalar array in reverse order
Arsort ()-Sorts the Values in a associative array in reverse order
Krsort ()-Sorts the Keys in a associative array in reverse order
In the "Next part", we look at the ' how ' Get a random value ' from ' an array.
