Array and Mysql insert using PDO - php

Question

0I have an array ($dataArray) in the following format which is created from a csv file:
The CSV is processed as follows:
function csvstring_to_array($string, $separatorChar = ',', $enclosureChar = '"', $newlineChar = "\n") {
// #author: Klemen Nagode
$array = array();
$size = strlen($string);
$columnIndex = 0;
$rowIndex = 0;
$fieldValue="";
$isEnclosured = false;
for($i=0; $i<$size;$i++) {
$char = $string{$i};
$addChar = "";
if($isEnclosured) {
if($char==$enclosureChar) {
if($i+1<$size && $string{$i+1}==$enclosureChar){
// escaped char
$addChar=$char;
$i++; // dont check next char
}else{
$isEnclosured = false;
}
}else {
$addChar=$char;
}
}else {
if($char==$enclosureChar) {
$isEnclosured = true;
}else {
if($char==$separatorChar) {
$array[$rowIndex][$columnIndex] = $fieldValue;
$fieldValue="";
$columnIndex++;
}elseif($char==$newlineChar) {
echo $char;
$array[$rowIndex][$columnIndex] = $fieldValue;
$fieldValue="";
$columnIndex=0;
$rowIndex++;
}else {
$addChar=$char;
}
}
}
if($addChar!=""){
$fieldValue.=$addChar;
}
}
if($fieldValue) { // save last field
$array[$rowIndex][$columnIndex] = $fieldValue;
}
return $array;
}
$dataArray = csvstring_to_array( file_get_contents("ACS_MONTHLY_DUES - Jun 2020.csv"));
echo '<pre>';
print_r($dataArray);
echo '</pre>';

I need to insert it in my mysql DB using PDO. I tried the following and it is not working:
include_once('inc/connstring.inc.php');
$stmt = $conn->prepare("INSERT INTO customer(subscriber_code, subscriber_id, region,center,subscriber_name,subscriber_phone,package,stb_nos,last_month_payment,amount_due,minimum_recharge,total_payable,expiry_date,pay_amount,current_balance)
VALUES(:subscribercode, :subscriberid, :region,:center,:subscribername,:subscriberphone,:package,:stbnos,:lastmonthpayment,:amountdue,:minimumrecharge,:totalpayable,:expirydate,:payamount,:currentbalance)");
foreach($dataArray as $row) {
$stmt->execute(array(
':subscribercode' => $row['SUBSCRIBER CODE'],
':subscriberid' => $row['SUBSCRIBER_ID'],
':region' => $row['REGION'],
':center' => $row['CENTER'],
':subscribername' => $row['SUBSCRIBERNAME'],
':subscriberphone' => $row['SUBSCRIBERPHONE'],
':package' => $row['BOUQ'],
':stbnos' => $row['STB_NOS'],
':lastmonthpayment' => $row['LAST MONTH PAYMENT'],
':amountdue' => $row['AMOUNT_DUE'],
':minimumrecharge' =>$row['MINIMUM_RECHARGE'],
':totalpayable' => $row['TOTAL_PAYABLE'],
':expirydate' => $row['EXPIRY_DATE'],
':payamount' => $row['PAY_AMOUNT'],
':currentbalance' => $row['CURRENT BALANCE']));
}
It is not working. Invalid argument supplied for foreach()
What am i doing wrong?? Requesting help from php experts...
Thanks in advance.
update:
Solved myself. Changed code to convert CSV to an associative array and now everything works fine.
Array
(
[0] => Array
(
[REGION] => XXX
[CENTER] => XXXXX
[SUBSCRIBER CODE] =>UK91002970
[SUBSCRIBER_ID] => 61610070
[SUBSCRIBERNAME] => XXXXX
[SUBSCRIBERPHONE] => XXXXXXX
[BOUQ] => UK FTA-1
[STB_NOS] => 1
[LAST MONTH PAYMENT] => 0
[AMOUNT_DUE] => 0
[MINIMUM_RECHARGE] => 221
[TOTAL_PAYABLE] => 221
[EXPIRY_DATE] => 08-06-2020
[PAY_AMOUNT] => 0
[CURRENT BALANCE] => 0
)

Answer 1

Your array $dataArray contains this:
Array
(
[0] => Array
(
[0] => REGION
[1] => CENTER
[2] => SUBSCRIBER CODE
[3] => SUBSCRIBER_ID
[4] => SUBSCRIBERNAME
[5] => SUBSCRIBERPHONE
[6] => BOUQ
[7] => STB_NOS
[8] => LAST MONTH PAYMENT
[9] => AMOUNT_DUE
[10] => MINIMUM_RECHARGE
[11] => TOTAL_PAYABLE
[12] => EXPIRY_DATE
[13] => PAY_AMOUNT
[14] => CURRENT BALANCE
)
[1] => Array
(
[0] => XXX
[1] => XXX
[2] => UK91002970
[3] => 61610070
[4] => XXXXX
[5] => XXXXXX
[6] => UK FTA-1
[7] => 1
[8] => 0
[9] => 0
[10] => 221
[11] => 221
[12] => 08-06-2020
[13] => 0
[14] => 0
)
You try to apply values values into your SQL by using REGION, CENTER, SUBSRICBER CODE etc. but you're mixing up keys with values
This array does not include $row['REGION'], does not include $row['CENTER'] etc...
If you're doing like this:
foreach($dataArray as $row) {
$stmt->execute(array(
':subscribercode' => $row['SUBSCRIBER CODE'],
':subscriberid' => $row['SUBSCRIBER_ID'],
etc...
}
then the array $dataArray would have to look like this:
Array
(
['SUBSCRIBER CODE'] => {value}
['SUBSCRIBER_ID'] => {value}
['SUBSCRIBERNAME'] => {value}
etc
)
One solution would be if (if I understand the array structure correctly) to apply keys from second and further based on first elements values
Lets say we have this:
Array
(
[0] => Array
(
[0] => REGION
[1] => CENTER
[2] => SUBSCRIBER CODE
[3] => SUBSCRIBER_ID
)
[1] => Array
(
[0] => XXX
[1] => XXX
[2] => UK91002970
[3] => 61610070
)
[2] => Array
(
[0] => XXX
[1] => XXX
[2] => UK91002971
[3] => 61610217
)
[3] => Array
(
[0] => XXX
[1] => XXX
[2] => UK91002972
[3] => 61610218
)
)
then first element contains: ['REGION', 'CENTER', 'SUBSCRIBER CODE','SUBSCRIBER_ID']
and second to fourth element contains the actual values "mapped to region, center , subscriber code, subscriber id".
A solution would be:
$dataArray = [];
$dataArray[] = ['REGION', 'CENTER', 'SUBSCRIBER CODE','SUBSCRIBER_ID'];
$dataArray[] = ['XXX', 'XXX', 'UK91002970', '61610070'];
$dataArray[] = ['XXX', 'XXX', 'UK91002971', '61610217'];
$dataArray[] = ['XXX', 'XXX', 'UK91002972', '61610218'];
$keys_apply = array_values($dataArray[0]); //get all values of first item in array
$i = 0;
foreach($dataArray as $key=>$item) {
if ($i>0) { //skip first item
$index = 0; //We know that index are 0 and above we start with zero here and
//and add one for each iteration
foreach($item as &$ik) {
//create new item with mapped key-value from first item in array but with
//the same value ($ik)
$dataArray[$key][$keys_apply[$index]] = $ik;
//Unset removes $dataArray[1][0], [1][1], [1][2] etc.
unset($dataArray[$key][$index]);
//Next element in this inner array
$index++;
}
}
$i++;
}
You would then have:
Array
(
[0] => Array
(
[0] => REGION
[1] => CENTER
[2] => SUBSCRIBER CODE
[3] => SUBSCRIBER_ID
)
[1] => Array
(
[REGION] => XXX
[CENTER] => XXX
[SUBSCRIBER CODE] => UK91002970
[SUBSCRIBER_ID] => 61610070
)
[2] => Array
(
[REGION] => XXX
[CENTER] => XXX
[SUBSCRIBER CODE] => UK91002971
[SUBSCRIBER_ID] => 61610217
)
[3] => Array
(
[REGION] => XXX
[CENTER] => XXX
[SUBSCRIBER CODE] => UK91002972
[SUBSCRIBER_ID] => 61610218
)
)
And then your original
foreach($dataArray as $row) {
$stmt->execute(array(
':subscribercode' => $row['SUBSCRIBER CODE'],
etc...
}
would work.
