Arrays:

 

 

Arrays are used to store data just like a variable; a variable store single data but arrays store multiple data. There are three types of array in php.

 

Numeric Arrays

 

Associative Arrays

 

Multi-dimensional Arrays

 

 

Syntax:

 

 

$cars=array("Saab", “Volvo","BMW","Toyota");     //Numeric arrays

$ages = array("Peter"=>32, "Quagmire"=>30, "Joe"=>34);   //Associative array

 

 

Remove array element in PHP:

 

 

To remove array element in php we use built in unset () function that was used for removing a variable in php.  The unset () function takes element as a parameter and remove that element from array.

 

 

Code:

 

<?

$dogs = array('A' => 'C', 'B' => 'D','X' => 'Y', 'Q' => 'T');

printf("%s,", var_export($dogs, TRUE));

 

unset($dogs['X']);

printf("%s,", var_export($dogs, TRUE));

?>

 

 

Above is a simple code to remove an array element using unset () function in php.

 

This simple article tells that how we can remove an element from arrays in php.
