Class Validateparameterconfig

{

public static function GetConfig ($key)

{

' Allow_exist ' =>true or allow_exist does not exist to indicate that the parameter must be passed

$_config = Array (

' Test ' =>array (

' Letter_number ' =>array (' rexp ' = ' letter_number ', ' allow_exist ' =>true),

' Number ' =>array (' rexp ' = ' number ', ' min_length ' =>1' allow_exist ' =>false '),

' Account ' =>array (' rexp ' = ' account ', ' max_length ' =>20),

)

);

if (Isset ($_config[$key])) {

return $_config[$key];

} else {

return $config _not_defind;

}

}

}

Examples of Use:

The parameters sent from the application end are

$arr = Array (' letter_number ' = ' abc123 ', ' account ' = ' acb1234_ ');

Parameter Validation

$_msg = Validation::validate ($arr, ' test ');

if ($_msg!== null) {

Return $_msg. ' is invalid parameter ';

}
