The array() function is an inbuilt function in PHP which is used to create an array. There are three types of array in PHP:
- Indexed array: The array which contains numeric index.
Syntax:array( val1, val2, val3, ... )
- Associative array: The array which contains name as keys.
Syntax:array( key=>val, key=>val, key=>value, ... )
- Multidimensional array: The array which contains one or more arrays.
Syntax:array( array( val11, val12, ...) array( val21, val22, ...) ... )
Parameters: This function accepts atmost two parameters as mentioned above and described below:
- val: This parameter is used to hold the value of array.
- key: This parameter is used to hold the key value:
Return Value: This function returns an array of parameters.
Below programs illustrates the array() function in PHP:
Program 1: This example illustrate the Indexed array.
<?php // Create an array $sub = array("DBMS", "Algorithm", "C++", "JAVA"); // Find length of array $len = count( $sub ); // Loop to print array elements for( $i = 0; $i < $len; $i++) { echo $sub[$i] . "\n"; } ?> |
Output:
DBMS Algorithm C++ JAVA
Program 2: This example illustrate the Associative array.
<?php // Declare an associative array $detail = array( "Name"=>"neveropen", "Address"=>"Noida", "Type"=>"Educational site"); // Display the output var_dump ($detail); ?> |
Output:
array(3) {
["Name"]=>
string(13) "neveropen"
["Address"]=>
string(5) "Noida"
["Type"]=>
string(16) "Educational site"
}
Program 3: This example illustrate the Multidimensional array.
<?php // Declare 2D array $detail = array(array(1, 2, 3, 4), array(5, 6, 7, 8)); // Display the output var_dump ($detail); ?> |
Output:
array(2) {
[0]=>
array(4) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
[3]=>
int(4)
}
[1]=>
array(4) {
[0]=>
int(5)
[1]=>
int(6)
[2]=>
int(7)
[3]=>
int(8)
}
}
