I want to get some data from my oracle database into php through a html form where I search by a string which exists into a column.

<?php
if(isset($_POST['submit'])){
if(isset($_GET['go'])){
if(preg_match("/^[A-Z0-9]+/", $_POST['name'])){
$name=$_POST['name'];
// Connects to the XE service (i.e. database) on the "localhost" machine
$conn = oci_connect('user', 'pwd', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT deejays.name,available_dates.data,available_dates.venue,available_dates.location FROM deejays,available_dates WHERE deejays.name LIKE '%W&W%' and pk_id=fk_id');
oci_execute($stid);
echo "<table border='1'>\n";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>\n";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";

You need to modify your query to include bindable parameters.您需要修改查询以包含可绑定参数。 Here is part of example 4 from the documentation for the oci_bind_name function, which you simply need to adapt to suit your application:以下是oci_bind_name函数文档中示例 4的一部分，您只需对其进行调整以适合您的应用程序：
$sql = 'SELECT last_name FROM employees WHERE department_id = :didbv ORDER BY last_name';
$stid = oci_parse($conn, $sql);
$didbv = 60;
oci_bind_by_name($stid, ':didbv', $didbv);
oci_execute($stid);
while (($row = oci_fetch_array($stid, OCI_ASSOC)) != false) {
echo $row['LAST_NAME'] ."<br>\n";
}
The documentation includes a very good description of what binding is, how to do it, and why it's important for application performance and security.该文档很好地描述了绑定是什么、如何进行以及为什么它对应用程序性能和安全性很重要。
