Question

可能重复：
PHP Error: mysql_fetch_array() expects parameter 1 to be resource, boolean given

当我运行我的脚本时，我继续得到这些错误，我无法弄清楚我需要修复什么，因为现在它不会显示任何像我需要它的PHP。

这是我收到的错误。

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in    /Applications/XAMPP/xamppfiles/htdocs/WordOfMouth/root/pages/profile_page/profile_page.php on line 38

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/WordOfMouth/root/pages/profile_page/profile_page.php on line 44

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in  /Applications/XAMPP/xamppfiles/htdocs/WordOfMouth/root/pages/profile_page/profile_page.php on line 136

任何帮助都会令人难以置信。

在以下两行代码中：

$sql = mysql_query("SELECT * FROM myMembers WHERE id='$id' LIMIT 1");
if (mysql_num_rows($sql) === 0) { // evaluate the count

如果mysql_query失败，则您没有可以传递给mysql_num_rows()的可行resource。

您应首先检查以确保查询实际运行：

$sql = mysql_query("SELECT * FROM myMembers WHERE id='$id' LIMIT 1");
if (!$sql) {
    // query failed
    echo "Query failed: " . mysql_error();
} else {
    $num_rows = mysql_num_rows($sql);
    // rest of your code
}

因为你有===，所以表达式mysql_num_rows($sql) === 0的计算结果为true，因为函数返回了null，因为它被调用了一个错误的值。因此，您遇到的问题是使用无效资源调用mysql_fetch_array。

主要线索是：mysql_num_rows() expects parameter 1 to be resource, boolean given。

它需要一个资源，但它被赋予一个布尔值，它无法使用。因此，您可以调查传递给它的变量的值以及为什么它是bool而不是资源（在这种情况下，因为查询失败）。

mysql_fetch_array（）期望参数1是资源，给定布尔值
