I have a huge file (around 4-5 GB containing 20 million rows) which has text like:
Actually above is an extracted file from a Sql Server with each field delimited by <EOFD> and each row ends with <EORD>. I need to split the file into chunks of maybe 2 million rows. Now since this is not a normal delimited file as its basically a file with a single huge line having <EORD> as the indicator for each row end.
Can someone please advise how can I proceed with the same?

dbx_fetch_row
DBX_FETCH_ROW(3) 1 DBX_FETCH_ROW(3)dbx_fetch_row - Fetches rows from a query-result that had the DBX_RESULT_UNBUFFEREDflag setSYNOPSIS
mixed dbx_fetch_row (object $result_identifier)
DESCRIPTION dbx_fetch_row(3) fetches rows from a result identifier that had the DBX_RESULT_UNBUFFERED flag set.
When the DBX_RESULT_UNBUFFERED is not set in the query, dbx_fetch_row(3) will fail as all rows have already been fetched into the results
data property.
As a side effect, the rows property of the query-result object is incremented for each successful call to dbx_fetch_row(3).
PARAMETERS
o $result_identifier
- A result set returned by dbx_query(3).
RETURN VALUES
Returns an object on success that contains the same information as any row would have in the dbx_query(3) result data property, including
columns accessible by index or fieldname when the flags for dbx_query(3) were set that way.
Upon failure, returns 0 (e.g. when no more rows are available).
EXAMPLES
Example #1
How to handle the returned value
<?php
$result = dbx_query($link, 'SELECT id, parentid, description FROM table', DBX_RESULT_UNBUFFERED);
echo "<table>
";
while ($row = dbx_fetch_row($result)) {
echo "<tr>
";
foreach ($row as $field) {
echo "<td>$field</td>";
}
echo "</tr>
";
}
echo "</table>
";
?>
