A corresponding argument MUST be passed for each placeholder. 1178 * 1179 * For compatibility with old behavior, numbered or formatted string placeholders (eg, %1$s, %5s) will not have quotes 1180 * added by this function, so should be passed with appropriate quotes around them for your usage. 1181 * 1182 * Literal percentage signs (%) in the query string must be written as %%. Percentage wildcards (for example, 1183 * to use in LIKE syntax) must be passed via a substitution argument containing the complete LIKE string, these 1184 * cannot be inserted directly in the query string. Also see {@see esc_like()}. 1185 * 1186 * Arguments may be passed as individual arguments to the method, or as a single array containing all arguments.
