db2_fetch_row — Sets the result set pointer to the next row or requested row
$stmt
[, int $row_number
] ) : boolUse db2_fetch_row() to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.
To retrieve individual fields from the result set, call the db2_result() function.
Rather than calling db2_fetch_row() and db2_result(), most applications will call one of db2_fetch_assoc(), db2_fetch_both(), or db2_fetch_array() to advance the result set pointer and return a complete row as an array.
stmtA valid stmt resource.
row_numberWith scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.
Returns TRUE if the requested row exists in the result set. Returns
FALSE if the requested row does not exist in the result set.
Example #1 Iterating through a result set
The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result().
<?php
$sql = 'SELECT name, breed FROM animals WHERE weight < ?';
$stmt = db2_prepare($conn, $sql);
db2_execute($stmt, array(10));
while (db2_fetch_row($stmt)) {
$name = db2_result($stmt, 0);
$breed = db2_result($stmt, 1);
print "$name $breed";
}
?>

Example #2 i5/OS recommended alternatives to db2_fetch_row/db2_result
On i5/OS it is recommended that you use db2_fetch_both(), db2_fetch_array(), or db2_fetch_object() over db2_fetch_row()/db2_result(). In general db2_fetch_row()/db2_result() have more issues with various column types in EBCIDIC to ASCII translation, including possible truncation in DBCS applications. You may also find the performance of db2_fetch_both(), db2_fetch_array(), and db2_fetch_object() to be superior to db2_fetch_row()/db2_result().
<?php
$conn = db2_connect("","","");
$sql = 'SELECT SPECIFIC_SCHEMA, SPECIFIC_NAME, ROUTINE_SCHEMA, ROUTINE_NAME, ROUTINE_TYPE, ROUTINE_CREATED, ROUTINE_BODY, IN_PARMS, OUT_PARMS, INOUT_PARMS, PARAMETER_STYLE, EXTERNAL_NAME, EXTERNAL_LANGUAGE FROM QSYS2.SYSROUTINES FETCH FIRST 2 ROWS ONLY';
$stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));
while ($row = db2_fetch_both($stmt)){
echo "<br>db2_fetch_both {$row['SPECIFIC_NAME']} {$row['ROUTINE_CREATED']} {$row[5]}";
}
$stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));
while ($row = db2_fetch_array($stmt)){
echo "<br>db2_fetch_array {$row[1]} {$row[5]}";
}
$stmt = db2_exec($conn, $sql, array('cursor' => DB2_SCROLLABLE));
while ($row = db2_fetch_object($stmt)){
echo "<br>db2_fetch_object {$row->SPECIFIC_NAME} {$row->ROUTINE_CREATED}";
}
db2_close($conn);
?>
