A valid OCI statement identifier.
- statement
-
An optional second parameter can be any combination of the following constants:
- OCI_BOTH - return an array with both associative and numeric indices (the same as OCI_ASSOC + OCI_NUM). This is the default behavior.
- OCI_ASSOC - return an associative array (as oci_fetch_assoc() works).
- OCI_NUM - return a numeric array, (as oci_fetch_row() works).
- OCI_RETURN_NULLS - create empty elements for the NULL fields.
- OCI_RETURN_LOBS - return the value of a LOB of the descriptor.
Valorile întroarse

}
?>

$query = "SELECT id, name, lob_field FROM fruits";

oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row[2]->read(100)."<br>"; //this will output first 100 bytes from LOB
}
?>
Example#3 oci_fetch_array() with OCI_ASSOC example

$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";

while ($row = oci_fetch_array ($statement, OCI_ASSOC)) {

echo $row['NAME']."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output "Object id #1"
}
?>
Example#4 oci_fetch_array() with OCI_RETURN_LOBS example
<?php
$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, (OCI_NUM+OCI_RETURN_LOBS))) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output LOB's content
