In what ways can PHP developers enhance their debugging skills to troubleshoot issues like only reading one line of data from a CSV file in a PHP script?

Issue: When reading data from a CSV file in a PHP script, only one line of data is being read instead of all the lines present in the file. This could be due to not properly looping through the file or not handling the file pointer correctly. Solution: To fix this issue, PHP developers can enhance their debugging skills by checking the loop that reads the CSV file and ensuring that the file pointer is reset to the beginning of the file before reading it again.

<?php

$csvFile = 'data.csv';
$file = fopen($csvFile, 'r');

if ($file) {
    while (($data = fgetcsv($file)) !== false) {
        // Process each line of data
        print_r($data);
    }
    
    fclose($file);
} else {
    echo "Error opening file.";
}
