What are some common challenges when processing CSV files in PHP, especially when dealing with header and footer blocks?

One common challenge when processing CSV files in PHP is correctly handling header and footer blocks. To solve this, you can use the fgetcsv() function to read the CSV file line by line and check if it matches the header or footer format. You can then skip or process these blocks accordingly. 

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

// Read and process header block
$header = fgetcsv($csvFile);
if ($header[0] == 'Header') {
    // Process header block
}

// Read and process data rows
while (($data = fgetcsv($csvFile)) !== false) {
    // Process data rows
}

// Read and process footer block
$footer = fgetcsv($csvFile);
if ($footer[0] == 'Footer') {
    // Process footer block
}

fclose($csvFile);
