Example #1 oci_fetch() with defined variables
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200';
$stid = oci_parse($conn, $sql);
// The defines MUST be done before executing
oci_define_by_name($stid, 'LOCATION_ID', $locid);
oci_define_by_name($stid, 'CITY', $city);
oci_execute($stid);
// Each fetch populates the previously defined variables with the next row's data
while (oci_fetch($stid)) {
echo "Location id $locid is $city<br>\n";
}
// Displays:
// Location id 1000 is Roma
// Location id 1100 is Venice
oci_free_statement($stid);
oci_close($conn);
?>
Example #2 oci_fetch() with oci_result()
