// Using the json_encode() function $json = json_encode ( $value );
// Show output echo ( $json ) ;
?> Exit:{"name ":" GFG "," email ":" [email protected] "} Example 2:This example encodes a PHP multidimensional array to JSON representation.
// Declare a multidimensional array $value = array ( "name" = > "GFG" , array ( "email" = > "[email protected]" , "mobile" = > "XXXXXXXXXX" ) );
// Using the json_encode() function $json = json_encode ( $value );
// Show output echo ( $json ) ;
?> Exit:{"name ":" GFG "," 0 ": {" email ":" [email protected] "," mobile ":" XXXXXXXXXX "}} Example 3:This the example encodes PHP objects into JSON representation.
