例如,屏幕上显示 5 条记录。我希望 $questionnum 显示数字 5,但它一直说 $questionnum 为 0。我怎样才能获得与屏幕上输出的行数实际匹配的行数。EG 如果 5 行则显示数字 5,如果 3 行则显示数字 3 等等。
下面是代码:
// Execute
if (!$stmt->execute()) {
die("Error executing statement: $stmt->error");
}
$stmt->store_result();
// This will hold the search results
$searchResults = array();
$searchOption = array();
// Fetch the results into an array
if (!$stmt->num_rows()) {
$stmt->bind_result($dbQuestionContent,$dbOptionType);
while ($stmt->fetch()) {
$searchResults[] = $dbQuestionContent;
$searchOption[] = $dbOptionType;
}
}
if (isset($_GET['searchQuestion'])) {
// If $terms is not empty we did a query
if (!empty($terms)) {
$questionnum = $stmt->num_rows;
// If $searchResults is not empty we got results
if (!empty($searchResults)) {
echo"<p>Number of Questions Shown from the Search: <strong>$questionnum</strong></p>";
echo "<table border='1' id='resulttbl'>
foreach ($searchResults as $key=>$question) {
echo '<tr class="questiontd"><td>'.htmlspecialchars($question).'</td>';
echo '<td class="optiontypetd">'.htmlspecialchars($searchOption[$key]).'</td>';
}
echo "</table>";
}
