Can anyone point me to a really good end to

csv file and uploading it into MySQL via a
PHP script?
Actually, depending on the integrity of the data and the consistency of
the format in the CSV file, you can do this simply and easily using just
MySQL. Take a look at the following pages:
Thanks for that. As there will be a team of people creating the data
and loading it I need to do some validation etc before it goes into the
database.
Currently I have this and it looks like it might work:-
# Open file
$fptr = fopen($filename, "r");
# Check if file is open
if($fptr) {
$current_line = fgets($fptr,4096);
$retval = TRUE;
echo "open";
while($current_line && $retval)
{
$mystring=csv_string_to_array($current_line);
$query =
"insert into invw2wfinal
(
FIELD1,
FIELD2,
FIELD3,
FIELD4
)
values
(
'". mysql_real_escape_string($mystring[0]) ."',
'". mysql_real_escape_string($mystring[1]) ."',
'". mysql_real_escape_string($mystring[2]) ."',
'". mysql_real_escape_string($mystring[3]) ."'
)";
$result = mysql_query($query);
if(!$result)
{
echo "<h1>Processing halted due to Error No:";
echo mysql_errno().": ";
echo mysql_error()."<BR>";
echo "</h1>";
$retval = FALSE;
die;
}
elseif(mysql_affected_rows() == 0)
{
$retval = FALSE;
die;
}
set_time_limit(0);
$current_line = fgets($fptr,4096);
}
}
fclose($fptr);
function csv_string_to_array($str){
$expr="/,(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))/";
$results=preg_split($expr,trim($str));
return preg_replace("/^\"(.*)\"$/","$1",$results);
}
