How to Display Data from CSV file using PHP?

In this article, we will learn how to display data from a CSV file using PHP using fgetcsv(), str_getcsv and SplFileObject functions.

CSV file is a simple file format used to store data with comma-separated values, and each row in it represents a record in the tabular data. To read a CSV file using PHP, we will use the fgetcsv() function which reads a line from a CSV file and returns an array of values representing the CSV data present in that line.

Let’s understand this with the help of an example below −

Example 1

In this example, we will read a data CSV file using fgetcsv() function and display the values in a tabular format using HTML table tag.

The CSV file used in this example −

Data.csv

      echo '<tr>';
      foreach ($data as $value) {
        echo '<td>' . htmlspecialchars($value) . '</td>';
      }
      echo '</tr>';
    }
    echo '</table>';

    fclose($csvFile);
	?>

Example 2

In this example, we will read a Students CSV file containing their Name, Age, and Gender, and we will display their data in the tabular format using 3 different methods, using str_getcsv, fgetcsv, and SplFileObject methods respectively.
