Translate PHP script to read CSV file and return echo multiple times

Question

I have written a PHP script that reads a CSV file and publishes the resulting radio schedule on a website based on time and date. However, it appears it will be released twice.

The following is the script content:

<?php
// Step 1: Replace 'data.csv' with the path to your CSV file
$csvFile = 'schedule.csv';

// Step 2: Read CSV and store its contents in an array
if (($handle = fopen($csvFile, 'r')) !== false) {
    $csvData = [];
    while (($data = fgetcsv($handle)) !== false) {
        $csvData[] = $data;
    }
    fclose($handle);
} else {
    die("Error opening CSV file.");
}

// Step 3: Get the current day and time
$currentDay = date('l'); // l gives the full textual representation of the day (e.g., "Monday")
$currentHour = date('H'); // H gives the hour in 24-hour format (e.g., "13" for 1 PM)
// Adjust hour offset below.
$Hour = $currentHour 1;

// Step 4: Filter the array based on the current day and time
$filteredData = [];
foreach ($csvData as $row) {
    // Assuming that your CSV file has a "Day" column and a "Time" column
    $day = $row[0];
    $time = intval($row[1]);
$program_name= $row[2];
$program_when= $row[2];
$program_img= $row[4];

    // Check if the row matches the current day and time
   if ($day === $currentDay && $Hour >= $time) {
        $filteredData[] = $row;
    }
}

// Step 5: Display the filtered data with CSS classes for each row
if (count($filteredData) > 0) {


    foreach ($filteredData as $row) {
     

echo "<div class='row'>";
echo "<div class='col-5'>";
echo "<img src='$row[4]' width='90' height='90' border='0'>";
echo "</div>";
echo "<div class='col-7'>";
echo "<h3>$row[2]<br>$row[3]</h3>";
echo "</div>";
echo "</div>";
 
    }
} else {
    echo 'Not available.';
}

This is the data I tested with in a CSV file:

Friday,12,MMV,until 1pm,top_mmv.png
Friday,13,MMV,until 2pm,top_mmv.png
Friday,14,MMV,until 3pm,top_mmv.png
Friday,15,MMV,until 4pm,top_mmv.png

But when it gets to 2pm on Friday, it posts both the 1pm and 2pm rows. What did I do wrong?

Answer 1

You need to specify the conditions for collecting data,

if ($day === $currentDay && $Hour >= $time) {

For example, the current time now is 14 o'clock (add 1 hour is your adjustment).

$Hour >= $time

15 >= time from first line of csv is 12 - true
15 >= time from second line of csv is 13 - true
15 >= time from third line of csv is 14 - true
15 >= 15 - true

I think you can see where the problem is.
