In what ways can conditional statements be used in PHP to filter and process data based on specific criteria in a CSV file?

Conditional statements can be used in PHP to filter and process data from a CSV file based on specific criteria by checking each row against the conditions specified. By using conditional statements such as if, else if, and else, you can determine which rows meet the criteria and perform actions accordingly, such as displaying, storing, or manipulating the data. 

<?php

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

// Loop through each row in the CSV file
while (($row = fgetcsv($csvFile)) !== false) {
    // Check if the row meets the specified criteria
    if ($row[2] == 'criteria1' && $row[3] > 50) {
        // Process the data if the criteria are met
        echo "Data: " . implode(', ', $row) . "\n";
    }
}

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

?>
