Cron作业执行PHP文件

Question

I set my cronjob to run a php file every one minute. The php file access to the database to update a value in a row. Here is the php code

<?php 

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
else {
mysql_query("UPDATE tanlename SET status = 2 WHERE created < (NOW() - 
INTERVAL 1 MINUTE)");
}
mysqli_close($conn);
?>

I want the code to set the status of a post to 2 after 1 minute of the its posting time.

Answer 1

The problem is in the else here:

You need to change mysql_ to mysqli_ - not only is mysql_ deprecated but also because you're already using mysqli_ in $conn .

Then you need to specify the connection in the mysqli_query .

Update your old code from:

else {
mysql_query("UPDATE tanlename SET status = 2 WHERE created < (NOW() - 
INTERVAL 1 MINUTE)");
}

to this:

else {
    mysqli_query($conn, "UPDATE tanlename SET status = 2 WHERE created < (NOW() - INTERVAL 1 MINUTE)");
}
