Array in PHP

Elements is the name of the data on the array and the location of each of the elements indicated by an index. Array starting at index 0. Array has two boundaries, the lower limit and upper limit.

The dimensions of the array can be one or more dimensions. Some examples dimensional array:

a. One-dimensional Array (representing vector shapes)

b. Two-dimensional array (representing the matrix form)

c. Three-dimensional array (representing the shape of the room)

Writing array syntax:

Array[];

$variabelname=$array(“elemen0”,”elemen1”,”elemen2”,”elemen..n”);

Example:

$flower[ ]=”Roses”;

$flower[ ]=”Orchid”;

$flower[ ]=”Jasmine”;

$flower[ ]=”Sunflower”;

print($flower[2]);

The result is Jasmine

2. The second form of array declaration

$flower=array(“Roses”,”Orchid”,”Jasmine”,”Sunflower”);

Print($flower[1]);

The result is Orchid
