sqlite_escape_string - Escapes a string for use as a query parameter

SYNOPSIS
       string sqlite_escape_string (string  $item)

DESCRIPTION
       sqlite_escape_string(3)	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.

	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).

PARAMETERS
	      o $item
		- The string being quoted.  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.

RETURN VALUES
	Returns an escaped string for use in an SQLite SQL statement.

NOTES
       Note

	       Do  not	use  this  function to encode the return values from UDF's created using sqlite_create_function(3) or sqlite_create_aggre-
	      gate(3) - use sqlite_udf_encode_binary(3) instead.

       Warning

	      addslashes(3) should NOT be used to quote your strings for SQLite queries; it will lead to  strange  results  when  retrieving  your
	      data.

SEE ALSO
       sqlite_udf_encode_binary(3).
