Array in PHP One-dimensionalD ,Two-dimensional and Multi-dimensional

$array=array(); // One D
$array=array(array()); // Two D

for One D

$colorList = array("red","green","blue","black","white");



$colorList[0] = "red";

$colorList[1] = "green";

$colorList[2] = "blue";

$colorList[3] = "black";

$colorList[4] = "white";


If you don't want to bother about numbering, you can create your array as this:
Creating array without numbering

$colorList[] = "red";

$colorList[] = "green";

$colorList[] = "blue";

$colorList[] = "black";

$colorList[] = "white";




Code to display all the elements in the array


for ($i=0;$i<count($colorList);$i++){

echo $colorList[$i];

}




foreach ($colorList as $value) {

echo $value;

}

Associative arrays

Defining an associated array

$colorList = array("apple"=>"red",

 "grass"=>"green",

 "sky"=>"blue",

 "night"=>"black",

 "wall"=>"white");




Creating the Multidimensional array

$myLists['colors'] = array("apple"=>"red",

 "grass"=>"green",

 "sky"=>"blue",

 "night"=>"black",

 "wall"=>"white");                     

$myLists['cars'] = array("BMW"=>"M6",

 "Mercedes"=>"E 270 CDI",

 "Lexus"=>"IS 220d",

 "Mazda"=>"6",

"Toyota"=>"Avensis");

Accessing the multidimensional array

echo $myLists['cars']['Toyota'];







Two dimensional array:

$array = array(
    array(0, 1, 2),
    array(3, 4, 5),
);

or 

$array = array();

$array[] = array(0, 1, 2);
$array[] = array(3, 4, 5);
