Homework and Emergencies Homework & Coursework Questions Converting .dat to UNIX Post 303037520 by RudiC on Sunday 4th of August 2019 03:10:25 AM

I don't think we're dealing with "converting sth. to UNIX". .dat files usually are binary files with an underlying structure understood (more or less) only by the creating and consuming application(s). They are not text files. dos2unix does not apply / do any valuable work. In contrary, it will garble the data.



So, a binary transfer is a must, and on the receiving side an apt application should read, evaluate, and use the binary data. You may want to (binary) compare files before and after transfer.

SQLITE_ESCAPE_STRING(3) 												   SQLITE_ESCAPE_STRING(3)

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). PHP Documentation Group SQLITE_ESCAPE_STRING(3)
