# Array in PHP
Array is collection of same data types. In PHP, an array stores multiple values in one single variable. I.e. an array is a special variable, which can store multiple values in one single variable.\
In PHP, there are three types of array.
1. Numeric Array
2. Associative Array
3. Multidimensional Array
##### Numeric Array:
A numeric array stores each array element with a numeric index. i.e. When we create numeric array, index automatically or manually assigned for each value of array at creation time.
There are two methods to create numeric array.
##### 1. Index automatically assigned( index starts at 0)
Syntax : $array_name = array (element1, element 2,……);
##### 2. Index manually assigned.
Syntax: $array_name[0] = element1;
$array_name[1] = element2;
..........................
..........................
$array_name[N] = elementN ;
Let’s we have an example, how to implement numeric array in php.
##### Example:
```
Numeric Array
```
##### Output:
**Note:** ‘print_r’ is the function to print all values of array.
##### Associative Array:
An associative array, each ID key is associated with a value. When storing data about specific named values, a numerical array is not always the best way to do it. With associative arrays we can use the values as keys and assign values to them.
##### Syntax: Create associative array
$ass_array = array ( "index_Id1" => value , "index_id1" => value, .........);
##### Example: Let’s we have an example, how to implement Associative array in PHP.
```
Switch Statement 22, "Vineet" => 24, "Pandey" => 25); print_r ($ass_array); ?>
```
##### Output:
##### Multidimensional Array:
In a multidimensional array, each element in the main array can also be an array. And each element in the sub-array can be an array, and so on.
##### Syntax:
```
$multi_array = array ( ele1 => array1 ( subele1, subele2, ....... ....... subeleN ), ele2 => array2 ( subele1, subele2, ....... ........ ), ........ ........ eleN = arrayN () ) ;
```
Let’s we have an example, how to implement multidimensional array.
##### Example:
```
Multidimensional Arrray Test array ( "Twash", "Brooker", "Hinggbotton" ) , "Subject" => array ( "Math", "Physics", "Chemistry" ) , "School" => array ( "Bal vikas", "Jaipuria", "Anandram" ) ); // Print multidimensional array with print_r function print_r ($multi_array) ; ?>
```
##### Output:
Example: Let’s we have an example, how to implement one-dimensional, two-dimensional and multi-dimensional array in php.
```
Array Test "."This is one- dimensional array".""."";$subject = array("Math","Physics","Chemistry","English","Hindi","Geography","Civics","History","Economics","Political Science"); // print one dimensional element using foreach loopforeach ($subject as $value){ echo ($value."");} // Declare two-dimensional array $matrix = array ( array (1,2,3), array (4,5,6), array (7,8,9) ); echo ""."This is two dimensional array"."
"."";// Print two dimensional array element for($row = 0 ; $row <3 ; $row++) { for($col = 0 ;$col <3 ; $col++) { echo $matrix[$row][$col]."\t"."\t"; } echo ""; }// Declare multi-dimensional array$organization = array (array (array ("Tech","Ankur","kumar"), array ("Sales","Arvind","javed"), array ("HR", "Bhabha","Phoole") ), array (array ("Tech","Govind","Reimya"), array ("Sales","Guru","Chaurasia"), array ("HR", "Bhabha","Phoole") ) );echo ""."This is multidimensional Array"."
".""; for($layer = 0 ; $layer <2 ; $layer++) { for($row =0; $row<3;$row++) { for($col =0;$col<3 ;$col++) { echo $organization[$layer][$row][$col]."\t"; } echo "" ; } echo ""; } ?>
```
