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
Name, Age, City John, 30, New York Mary, 25, Los Angeles Tom, 40, Chicago
Filename: index.php
<html lang="en">
<head>
<title>How to Display Data from CSV file using PHP?</title>
</head>
<body>
<h3>How to Display Data from CSV file using PHP?</h3>
<?php
$csvFile = fopen('Data.csv', 'r');
echo '<table>';
while (($data = fgetcsv($csvFile, 1000, ",")) !== FALSE) {
echo '<tr>';
foreach ($data as $value) {
echo '<td>' . htmlspecialchars($value) . '</td>';
}
echo '</tr>';
}
echo '</table>';
fclose($csvFile);
?>
</body>
</html>
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.
Students.csv
Name,Age,Gender John Doe,25,Male Jane Smith,30,Female Bob Johnson,40,Male Sara Lee,22,Female
Filename: index.php
<html lang="en">

<h3>How to Display Data from CSV file using PHP?</h3>
<!-- Method 1: str_getcsv -->
<?php
$csvData = file_get_contents('students.csv');
$rows = str_getcsv($csvData, "<br>"); // Split CSV data into rows
echo '<h4>Method 1: str_getcsv</h4>';
echo '<table>';
echo '<thead><tr><th>Name</th><th>Age</th><th>Gender</th></tr></thead>';
echo '<tbody>';
foreach ($rows as $row) {
$values = str_getcsv($row, ","); // Split row into values
echo '<tr>';
foreach ($values as $value) {
echo '<td>' . htmlspecialchars($value) . '</td>';
}
echo '</tr>';
}
echo '</tbody></table>';
?>
<!-- Method 2: Combine fgetcsv() and HTML -->
<?php
echo '<h4>Method 2: Combine fgetcsv() and HTML</h4>';
$csvFile = fopen('students.csv', 'r');
echo '<table>';
echo '<thead><tr><th>Name</th><th>Age</th><th>Gender</th></tr></thead>';
echo '<tbody>';
while (($data = fgetcsv($csvFile, 1000, ",")) !== FALSE) {
echo '<tr>';
foreach ($data as $value) {
echo '<td>' . htmlspecialchars($value) . '</td>';
}
echo '</tr>';
}
echo '</tbody></table>';
fclose($csvFile);
?>
<!-- Method 3: using SplFileObject -->
<?php
echo '<h4>Method 3: using SplFileObject</h4>';
$csvFile = new SplFileObject('students.csv', 'r');
$csvFile->setFlags(SplFileObject::READ_CSV);
echo '<table>';
echo '<thead><tr><th>Name</th><th>Age</th><th>Gender</th></tr></thead>';
echo '<tbody>';
foreach ($csvFile as $row) {
echo '<tr>';
foreach ($row as $value) {
echo '<td>' . htmlspecialchars($value) . '</td>';
}
echo '</tr>';
}
echo '</tbody></table>';
?>
Conclusion
In conclusion, displaying data from a CSV file using PHP is a straightforward process using the fgetcsv() function. With the help of HTML tags, we easily displayed the data in a tabular format. By following the examples provided in this article, we learned to read and display data from CSV files in PHP, which can be useful in various applications.
