What is the significance of using explode() function in PHP when reading from a CSV file?

When reading from a CSV file in PHP, the explode() function is significant because it allows you to split each line of the CSV file into an array of values based on a specified delimiter, typically a comma. This is useful for processing the data in the CSV file and accessing individual values for further manipulation or analysis.

$csvFile = fopen('data.csv', 'r'); // Open the CSV file for reading

while (($data = fgetcsv($csvFile)) !== false) {
    $values = explode(',', $data[0]); // Split the CSV row into an array of values
    // Process the values as needed
}

fclose($csvFile); // Close the CSV file
