SQLite3::exec(): unrecognized token: "'Date" - php

Question

I get the error message SQLite3::exec(): unrecognized token: "'Date" when I insert a command into a SQLite database.
If I have the SQL commands echoed and execute them via the console, this also works. The data for this comes from a dbase database.
If I enter a string for fieldname the insert commands will work.
$field=unpack( "a11fieldname/A1fieldtype/Voffset/Cfieldlen/Cfielddec", substr($buf,0,18));
$db = new SQLite3('databases/test.db');
$sqlCode .= "INSERT INTO HEADER (name) VALUES ('".$field['fieldname']."');";
$db-> exec($sqlCode);

Answer 1

Would be that much easy to use prepare satement against sql injections
If I enter a string for fieldname the insert commands will work
make sure if fieldname is a text value
I am using pdo :
$sqlCode = "INSERT INTO header VALUES (:name)";
$query = $db->prepare($sqlCode);
$query->bindValue(':name', $field['fieldname'], SQLITE3_TEXT);
$result = $query->execute();
EDIT : Error says unrecognized token Date, So, if fieldname is a date you might need to change SQLITE3_TEXT to SQLITE3_BLOB OR SQLITE3_INTEGER Usualy not needed.
But you need to insert date into date column not into name column
EDIT 2 :
it's a bit complicated.
See here for a full description of the dbf file format.
So it would be best if you could use a library to read and write the dbf files.
If you really need to do this yourself, here are the most important parts:
Dbf is a binary file format, so you have to read and write it as binary. For example the number of records is stored in a 32 bit integer, which can contain zero bytes.
You can't use string functions on that binary data. For example strlen() will scan the data up to the first null byte, which is present in that 32 bit integer, and will return the wrong value.
If you split the file (the records), you'll have to adjust the record count in the header.
When splitting the records keep in mind that each record is preceded by an extra byte, a space 0x20 if the record is not deleted, an asterisk 0x2A if the record is deleted. (for example, if you have 4 fields of 10 bytes, the length of each record will be 41) - that value is also available in the header: bytes 10-11 - 16-bit number - Number of bytes in the record. (Least significant byte first)
The file could end with the end-of-file marker 0x1A, so you'll have to check for that as well.

Final Word : you need DBF library
