function db_like in Drupal 7

Same name and namespace in other branches

1. 8 core/includes/database.inc \db_like()

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:

$result = db_query('SELECT * FROM person WHERE name LIKE :pattern', array(
  ':pattern' => db_like($prefix) . '%',
));

Backslash is defined as escape character for LIKE patterns in DatabaseCondition::mapConditionOperator().

Parameters

$string: The string to escape.

Return value

The escaped string.
