Question

我试图将大约1000条记录归入MySQL。但我的尝试仅在第一个查询上“插入”。之后，我收到'或死'错误消息。我尝试将if语句更改为随机数（除了五个），但它总是在第一次插入后死亡。我做错了什么？

$i=0;
foreach(.....){
    if($>5){
        insert($name, $phone);
    }
}

function insert($n, $p){

    $dbhost = "---"; 
    $dbuser = "---";
    $dbpass = "---";
    $dbname = "---";

    $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ("Error connecting to mysql");
    mysql_select_db($dbname);

    $query ="INSERT INTO foo (name, phone) VALUES ('$n', '$p')";
    mysql_query($query) or die('Error, query failed');  
    mysql_close();
}

Answer 1

这是你的代码

$i=0;
foreach(.....){
    if($>5){
        insert($name, $phone);
    }
}

function insert($n, $p){

    $dbhost = "---"; 
    $dbuser = "---";
    $dbpass = "---";
    $dbname = "---";

    $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ("Error connecting to mysql");
    mysql_select_db($dbname);

    $query ="INSERT INTO foo (name, phone) VALUES ('$n', '$p')";
    mysql_query($query) or die('Error, query failed');  
    mysql_close();
}

连接到MySQL只是为了插入一行，然后是disconnecting and reconnecting is a VERY EXPENSIVE OPERATION !!!

尝试重新组织它：

$dbhost = "---"; 
$dbuser = "---";
$dbpass = "---";
$dbname = "---";
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ("Error connecting to mysql");
mysql_select_db($dbname);
$i=0;
foreach(.....){
    if($>5){
        insert($name, $phone);
    }
}
mysql_close();

function insert($n, $p){
    $query ="INSERT INTO foo (name, phone) VALUES ('$n', '$p')";
    mysql_query($query) or die('Error, query failed');  
}

您是否收到主键错误？

MySQL查询仅通过循环第一次工作
