Using loops by reading data from a database - php

Question

I have a form with three fields that I want to read separately from the database
$_POST['wkNumer1'];
$_POST['wkNumer2'];
$_POST['wkNumer3'];
How can I read this data without repeating the same code 3 times? In this code, only the variable $wkNumer value will be change.
<?php
if (isset($_POST['show_diagram'])) {
$goodname = $_POST['htDriver'];
$wkNumer = $_POST['wkNumer1'];
// Table with data
$sql = "SELECT WorkingDay, OrderNo, NameFinish, Type FROM `status` where WEEK(WorkingDay) = :wknumer AND NameFinish = :nameFinish"; // SQL with parameters
$stmt = $conn->prepare($sql);
$stmt->bindParam("wknumer", $wkNumer);
$stmt->bindParam("nameFinish", $goodname);
$stmt->execute();
$OCSdatas = $stmt->fetchAll(PDO::FETCH_ASSOC);
$count = $stmt->rowCount();
$countWithoutE = 0;
$countE = 0;
foreach ($OCSdatas as $data) {
if ($data['Type'] != 'E') {
$countWithoutE = $countWithoutE + 1 ;
}
if ($data['Type'] == 'E') {
$countE = $countE + 1 ;
}
}
echo $goodname . '<br />';
echo $wkNumer . '<br />';
echo $countWithoutE . '<br>';
echo $countE . '<br>';
$countE = $countE/2;
$countTotal = $countWithoutE + $countE;
echo $countTotal/5 . '<br>';
echo $count/5;
}
?>

Answer 1

You can put the numbers inside an array and iterate through that array to execute the same code.
$goodname = $_POST['htDriver'];
// Add the numbers to an array which we can iterate
$numbers = [
$_POST['wkNumber1'],
$_POST['wkNumber2'],
$_POST['wkNumber3'],
];
// Prepare the statement only once before the loop and reuse it
$sql = "SELECT WorkingDay, OrderNo, NameFinish, Type FROM `status` where WEEK(WorkingDay) = :wknumer AND NameFinish = :nameFinish";
$stmt = $conn->prepare($sql);
// Loop through the numbers
foreach ($numbers as $number) {
// Add the current number
$stmt->bindParam("wknumer", $number);
$stmt->bindParam("nameFinish", $goodname);
$stmt->execute();
// Now have everything as you had before
$OCSdatas = $stmt->fetchAll(PDO::FETCH_ASSOC);
$count = $stmt->rowCount();
$countWithoutE = 0;
$countE = 0;
foreach ($OCSdatas as $data) {
if ($data['Type'] != 'E') {
$countWithoutE = $countWithoutE + 1 ;
}
if ($data['Type'] == 'E') {
$countE = $countE + 1 ;
}
}
echo $goodname . '<br />';
echo $wkNumer . '<br />';
echo $countWithoutE . '<br>';
echo $countE . '<br>';
$countE = $countE/2;
$countTotal = $countWithoutE + $countE;
echo $countTotal/5 . '<br>';
echo $count/5;
}

How does this work for you?
$workNumbers = array($_POST['wkNumer1'],$_POST['wkNumer2'],$_POST['wkNumer3']);
foreach($workNumbers as $wkNumer){
//Your Code block here
}
