Examples
Example #1 Displaying the Oracle error message after a connection error
<?php
$conn = oci_connect("hr", "welcome", "localhost/XE");
if (!$conn) {
$e = oci_error(); // For oci_connect errors do not pass a handle
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
?>
Example #2 Displaying the Oracle error message after a parsing error
<?php
$stid = oci_parse($conn, "select ' from dual"); // note mismatched quote
if (!$stid) {
$e = oci_error($conn); // For oci_parse errors pass the connection handle
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
?>
Example #3 Displaying the Oracle error message, the problematic statement,
and the position of the problem of an execution error
<?php
$stid = oci_parse($conn, "select does_not_exist from dual");
$r = oci_execute($stid);
if (!$r) {
$e = oci_error($stid); // For oci_execute errors pass the statement handle
print htmlentities($e['message']);
print "\n<pre>\n";
print htmlentities($e['sqltext']);
printf("\n%".($e['offset']+1)."s", "^");
print "\n</pre>\n";
