public function Connection::escapeLike in Drupal 8
Same name and namespace in other branches
- 9 core/lib/Drupal/Core/Database/Connection.php \Drupal\Core\Database\Connection::escapeLike()
Escapes characters that work as wildcard characters in a LIKE pattern.
The wildcard characters "%" and "_" as well as backslash are prefixed with a backslash. Use this to do a search for a verbatim string without any wildcard behavior.
For example, the following does a case-insensitive query for all rows whose name starts with $prefix:
$result = $injected_connection
->query('SELECT * FROM person WHERE name LIKE :pattern', array(
':pattern' => $injected_connection
->escapeLike($prefix) . '%',
));
Backslash is defined as escape character for LIKE patterns in Drupal\Core\Database\Query\Condition::mapConditionOperator().
Parameters
string $string: The string to escape.
Return value
string The escaped string.
