用于填充关联数组的快捷方式功能

Question

I'm extracting data and then creating an array like:

$foo = $_POST[ 'foo' ];
$bar = $_POST[ 'bar' ];

$val = array( 'foo' => $foo, 'bar' => $bar );

Is it possible to have a shortcut function?

Something like the following:

$val = array( someFunction( 'foo' ), someFunction( 'bar' ) );

Where:

function someFunction( $name ) {
   return( "$name" => $_POST[ $name ] ); // Does not work!
}

Answer 1

You're thinking in the right direction, but not nearly big enough!

You want to define an input schema like:

$input = $_POST;
$input_schema = array(
    "foo" => "string",
    "bar" => "string"
);
validate_input($input, $schema);

From then on you can safely use $input in accordance with your schema.
