PHP Array

Techno PHP

The array is the collection of similar data items. The array is used for same data types.
Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same data type
. Array remove the data complexity.

An array stores the multiple values .


Example


<
?php
$fruits = array("Banana", "Mango ", "Orange");
echo "I like " . $fruits[0] . ", " . $fruits[1] . " and " . $fruits[2] . ".";
?>
		
		
Run

Index of an array start from the 0 .
$fruits[0] ----- Zero index number of array .

$fruits[1] ----- Index number one of array .

$fruits[2] ----- Index number two of array .

If you have a list of items (a list of fruit names, for example), store the fruit in single variables could look like this:

$fruits[0]=”Banana”;

$fruits[1]=”Mango”;

$fruits[2]=”Orange”;



In another example of the array, we can define the index value one by one and print them like below example.

Example

<?php 
$x[0]=12;
$x[1]=14;
$x[2]=777;
$x[3]=44;
?>

Sr No <?php echo"$x[0]"; ?>

Sr No <?php echo "$x[1]"; ?>

Sr No <?php echo "$x[2]"; ?>

Sr No <?php echo "$x[3]"; ?>

Run
