			0 ignored issues – show Coding Style Comprehensibility introduced 2017-12-20 07:56 UTC by Report Bug Copy Issue Report The string literal `SELECT * FROM INFORMATIO...s AND COLUMN_NAME = %s` does not require double quotes, as per coding-style, please use single quotes. PHP provides two ways to mark string literals. Either with single quotes `'literal'` or with double quotes `"literal"`. The difference between these is that string literals in double quotes may contain variables with are evaluated at run-time as well as escape sequences. String literals in single quotes on the other hand are evaluated very literally and the only two characters that needs escaping in the literal are the single quote itself (`\'`) and the backslash (`\\`). Every other character is displayed as is. Double quoted string literals may contain other variables or more complex escape sequences. <?php $singleQuoted = 'Value'; $doubleQuoted = "\tSingle is $singleQuoted"; print $doubleQuoted; will print an indented: `Single is Value` If your string literal does not contain variables or escape sequences, it should be defined using single quotes to make that fact clear. For more information on PHP string literals and available escape sequences see the PHP core documentation. Loading history...

			0 ignored issues – show Bug introduced 2018-02-17 00:46 UTC by Report Bug Copy Issue Report It seems like you code against a specific sub-type and not the parent class `Give_DB` as the method `get_meta_type()` does only exist in the following sub-classes of `Give_DB`: `Give_DB_Donor_Meta`, `Give_DB_Form_Meta`, `Give_DB_Log_Meta`, `Give_DB_Meta`, `Give_DB_Payment_Meta`. Maybe you want to `instanceof` check for one of these explicitly? Let’s take a look at an example: abstract class User { /** @return string / abstract public function getPassword(); } class MyUser extends User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different sub-classes of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case. Add the method to the parent class: abstract class User { /** @return string / abstract public function getPassword(); /* @return string */ abstract public function getDisplayName(); } Loading history...
