sqlite_escape_string
说明
string sqlite_escape_string ( string item )
sqlite_escape_string() will correctly quote the string
specified by item
for use in an SQLite SQL statement. This includes doubling up
single-quote characters (') and checking for
binary-unsafe characters in the query string.
If the item contains a NUL
character, or if it begins with a character whose ordinal value is
0x01, PHP will apply a binary encoding scheme so that
you can safely store and retrieve binary data.
Although the encoding makes it safe to insert the data, it will render simple text comparisons and LIKE clauses in your queries unusable for the columns that contain the binary data. In practice, this shouldn't be a problem, as your schema should be such that you don't use such things on binary columns (in fact, it might be better to store binary data using other means, such as in files).
| 警告 |
addslashes() should NOT be used to quote your strings for SQLite queries; it will lead to strange results when retrieving your data. |
注意: Do not use this function to encode the return values from UDF's created using sqlite_create_function() or sqlite_create_aggregate() - use sqlite_udf_encode_binary() instead.
