How can PHP developers effectively manage memory limits when working with large JSON files?

PHP developers can effectively manage memory limits when working with large JSON files by using the `json_decode()` function with the `true` parameter to parse the JSON file incrementally instead of loading the entire file into memory at once. This allows developers to process the JSON data in smaller, more manageable chunks, reducing the risk of hitting memory limits. 

$jsonFile = 'large_file.json';
$handle = fopen($jsonFile, 'r');
$buffer = '';
while (($data = fread($handle, 1024)) !== false) {
    $buffer .= $data;
    $pos = strrpos($buffer, '}');
    if ($pos !== false) {
        $jsonObject = json_decode(substr($buffer, 0, $pos + 1), true);
        // Process the JSON object here
        $buffer = substr($buffer, $pos + 1);
    }
}
fclose($handle);
