What potential issues or pitfalls should be considered when working with JSON data in PHP?

Issue: Handling large JSON data can lead to memory exhaustion in PHP. To avoid this, consider using streaming techniques to process JSON data in chunks rather than loading the entire JSON into memory at once.

// Example of streaming JSON data in PHP
$filename = 'large_data.json';
$handle = fopen($filename, 'r');

while (!feof($handle)) {
    $chunk = fread($handle, 1024); // Read data in chunks
    // Process the chunk of JSON data
}

fclose($handle);
