PHP Arrays !!
In this article we will discuss about PHP Arrays, Types of PHP arrays in brief.
PHP Array
An array is a special variable that stores multiple values at a time.
Array can store values of int, string, float, character etc..
Types Of Array
There are three types of array
- Numeric
- Associative
- Multidimensional
Numeric Array
In numeric array each element having numeric key associated with it that is starting from 0.
You can use array() function to create array.
Syntax :
$array_name=array ( value1, value2 …valueN)
Program :
<?php
$my=array(‘A’,’B’,’C’);
print_r($my);
?>
Output:
Array( [0]=>A [1]=>B [2]=>C)
You can refer to individual element of an array in PHP script using its key values.
Progarm :
<?php
$myarray=array(‘A’,’B’,’C’);
echo $my[1];
?>
Output : B
In Numeric Array you can use for, while or do while loop to iterate through each element in array
because in numeric array key values are consecutive.
Program :
<?php
$myarray=array(“Apache”, “MySQL”, “PHP”);
for($i=0;$i<3;$i++)
{
echo $myarray*$i+.”<br>”;
}
?>
Output :
Apache
MySQL
PHP
Associative Array
The associative part means that arrays store element values in association with key values.
If you store an element in an array, in association with a key, all you need to retrieve it later from
that array is the key value.
Key may be either numeric or string.
You can use array() function to create associative array.
Syntax :
$array_name=array(key1=>value1, key1=>value1,….. keyN=>valueN);
Program :
<?php
$myarray=array(5=>”Apple”, 10=>”Mango”, 20=>”Grapes”);
print_r($my_array);
?>
Output:
Array([5]=>Apple [10]=>Mango [20]=>Grapes)
In associative array you cannot use for, while, do..while loop to iterate through each element in
array because in Associative array key value are not consecutive.
So you have to use foreach loop.
Program :
<?php
$myarray=array(“Name”=>”James” , “Age”=>25, “Gender”=>”Male” );
foreach($myarray as $item)
{
echo $item;
}
?>
Output :
James 25 Male
Multidimensional Array
PHP can easily support multidimensional arrays, with arbitrary numbers of key.And just as in one
dimensional arrays, there is no need to declare out intentions in advance. e:
The integer key of 0 stores a string, and the key 1 stores an array that ,in turn, has a string in it.
Creating array within another array using array() construct is as follows:
$basket=array( ‘fruit’ => array(‘red’ => ‘apple’,
‘yellow’ => ‘banana’,
‘black’ => ‘grapes’),
‘flower’ =>array(‘red’ => ‘rose’,
‘yellow’ => ‘sunflower’,
‘purple’ => ‘iris’)
);
It is simply an array with two values stored in association with keys.
Each of them values is an array itself. We can reference it like this
echo $basket*‘fruit’+*‘black’+;
Output : grapes
$kind=”flower”;
$color=”yellow”;
print(“ $basket *$kind+ *$color+”);
Output : sunflower
