使用php刷新随机1000次

Question

I have create a generate random in php and insert into mysql already. But I want to loop it 1000 times when I refresh for one time. All item must go to store in database. How can I do this?

function generateCode($length = 11) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, $charactersLength - 1)];
    }
    return $randomString;
}
echo $lucky_code=generateCode()."<br/>";

$servername = "localhost";
$username = "root";
$password = "";
$database = "random";

$cnt = mysql_pconnect($servername, $username, $password) or die(mysql_error());
mysql_select_db($database);
mysql_query("INSERT INTO tbl_code(code) VALUES('$lucky_code')",$cnt) or die(mysql_error());

Answer 1

You can use set_time_limit before the code and run loop 1000 times as below

set_time_limit(0);

function generateCode($length = 11) {
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $charactersLength = strlen($characters);
    $randomString = '';
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, $charactersLength - 1)];
    }
    return $randomString;
}

$servername = "localhost";
$username = "root";
$password = "";
$database = "random";

$cnt = mysql_pconnect($servername, $username, $password) or die(mysql_error());
mysql_select_db($database);
for ($i = 0; $i < 1000; $i++) {
    $lucky_code = generateCode();
    mysql_query("INSERT INTO tbl_code(code) VALUES('".$lucky_code."')", $cnt) or die(mysql_error());
}
