cubrid_real_escape_string — Escape special characters in a string for use in an SQL statement
説明
This function returns the escaped string version of the given string. It
will escape the following characters: '.
In general, single quotations are used to enclose character string. Double
quotations may be used as well depending on the value of ansi_quotes,
which is a parameter related to SQL statement. If the ansi_quotes value is
set to no, character string enclosed by double quotations is handled as
character string, not as an identifier. The default value is yes.
If you want to include a single quote as part of a character string, enter
two single quotes in a row.
パラメータ
unescaped_stringThe string that is to be escaped.
conn_identifierThe CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.
