Are there specific considerations when working with large files or images in PHP that could lead to memory limit issues?

When working with large files or images in PHP, it is important to be aware of the memory limit set in the php.ini file. Processing large files or images can quickly consume a lot of memory, potentially leading to memory limit issues and script failures. To avoid this, you can increase the memory limit in the php.ini file or use techniques like processing the file in chunks to reduce memory usage. 

// Increase memory limit
ini_set('memory_limit', '256M');

// Process large file in chunks
$handle = fopen('large_file.txt', 'r');
while (!feof($handle)) {
    $chunk = fread($handle, 1024); // Read 1KB at a time
    // Process the chunk
}
fclose($handle);
