PHP Forloop遍历数组并将当前数组项插入sql数据库，仅插入一条记录

Question

I have a script that gets data from a database, then loops through the results from the SELECT query by using a forloop and has a query that inserts the array data into another datbase. However only the first record gets inserted.

I get no errors

Here is the code.

//Get all from job
$getRecords = $connection->prepare("SELECT `CustomerFirstName`,`CustomerLastName`,`CASS_STD_LINE1`,`CASS_STD_LINE2`,`CASS_STD_CITY`,`CASS_STD_STATE`,`CASS_STD_ZIP`,`CustomerCounty`,`CustomerNumber`,`DealNumber`,`TradeIn_1_VIN`,`TradeIn_1_Make`,`TradeIn_1_Model`,`TradeIn_1_Year`,`FrontGross`,`BackGross`,`HoldBackAmount`,`VehicleYear`,`VehicleMake`,`VehicleModel`,`VehicleVIN`,`EntryDate`,`matched`,`notNew` FROM `auth` WHERE `matched` = ?");
$getRecords->execute(array($_POST['jobName']));
$gotRecords = $getRecords->fetchAll(PDO::FETCH_ASSOC);
$getRecords = null;


//Loop Through all records found with matching job name
for($i=0;$i<count($gotRecords); ++$i){
    $rec = $remote->prepare("INSERT INTO `cob_matched_records`(first) VALUES (?)");
    $rec->execute(array($gotRecords[$i]['CustomerFirstName']));

}

The problem with your script is most likely the line

$getRecords = null;

destroying the array before the code hits your for-loop.
(But that doesn't fit your description "However only the first record gets inserted.". Did you post the actual, unaltered code?)

The point (or one of the points) of prepared statements is that you prepare them once and then execute them multiple times with varying parameters. So, prepare the INSERT statement once before the loop and then execute it within with the current parameter(s):

// assuming PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION, otherwise error handling is missing....
// you might also be interested in http://docs.php.net/manual/en/pdo.begintransaction.php
$stmtSelect = $connection->prepare("SELECT `CustomerFirstName` FROM `auth` WHERE `matched` = ?");
$stmtInsert = $remote->prepare("INSERT INTO `cob_matched_records` (first) VALUES (?)");

$stmtSelect->execute( array($_POST['jobName']) );
foreach( $stmtSelect as $row ) {
    $stmtInsert->execute( array($row['cob_matched_records']) );
}
