How use the function NOW() in PHP

问题

I have a temporary table SQL. I have a filed that give me the name of the user that modified any information by get_current_user. I added another field type=DATETIME to recovre the date and the hour of the user modifcation.

In PHPI added it like all my function, but it got an error. The code is the following:

         $sql = "INSERT INTO  `...`.`correspondants_bis` 
    (`code_client` , `name`, `surname` ,`phone`, `fax`, `email`, `added_by`, `Date`, `condition`)

        VALUES ('" . $correspondent->getCodeClient() . "',
     '" . str_replace("'", "''", $correspondent->getName()) . "',
     '" . str_replace("'", "''", $correspondent->getSurname()) . "',
     '" . $correspondent->getPhone() . "', 
    '" . $correspondent->getFax() . "',
     '" . $correspondent->getEmail() . "', 
    '" . $user . "','" . NOW() . "',
    '1'
        );";

the error is:

Fatal error: Call to undefined function..... 
Attempted to call function "NOW" from namespace....

I know that NOW() is an SQL function, just I got you an example of insert because I don't know how I add it, and this following my select function:

 public function getCorrespondentByIdBis($id) {
        $statement = "SELECT * FROM `correspondants_bis` WHERE `id`='" . $id . "'";
        $result = $this->_db->query($statement);
        while ($data = $result->fetch()) {
            $correspondent = new CorrespondentBis($data['id'], $data['code_client'], $data['name'], $data['surname'], $data['phone'], $data['fax'], $data['email'], get_current_user(), NOW(), 0);
        }
       }
return $correspondent;
}

Can you tell me please, how I can change my code to resolve this issue ?

回答1:

now is not php function so replace

NOW()

date('Y-m-d H:i:s')

so your final code

$correspondent = new CorrespondentBis($data['id'], $data['code_client'], $data['name'], $data['surname'], $data['phone'], $data['fax'], $data['email'], get_current_user(), date('Y-m-d H:i:s'), 0);

2.no need to use quote , just use NOW() so your final query

$sql = "INSERT INTO  `...`.`correspondants_bis` 
     (`code_client` , `name`, `surname` ,`phone`, `fax`, `email`, `added_by`, `Date`, `condition`)

     VALUES ('" . $correspondent->getCodeClient() . "',
     '" . str_replace("'", "''", $correspondent->getName()) . "',
     '" . str_replace("'", "''", $correspondent->getSurname()) . "',
     '" . $correspondent->getPhone() . "', 
     '" . $correspondent->getFax() . "',
     '" . $correspondent->getEmail() . "', 
     '" . $user . "',
      NOW(),
     '1'
      );";

NOW() is a SQL function, so you don't need it in PHP:

$sql = "INSERT INTO  `...`.`correspondants_bis` 
    (`code_client` , `name`, `surname` ,`phone`, `fax`, `email`, `added_by`, `Date`, `condition`)

        VALUES ('" . $correspondent->getCodeClient() . "',
     '" . str_replace("'", "''", $correspondent->getName()) . "',
     '" . str_replace("'", "''", $correspondent->getSurname()) . "',
     '" . $correspondent->getPhone() . "', 
    '" . $correspondent->getFax() . "',
     '" . $correspondent->getEmail() . "', 
    '" . $user . "',NOW(),
    '1'
        );";

Sidenote: Building your SQL statements in this way, makes you susceptible to SQL injections. Better use prepared statements.
