What are common issues when using preg_split in PHP for splitting content based on specific characters or patterns?

One common issue when using preg_split in PHP for splitting content based on specific characters or patterns is that the delimiter may be interpreted as a regular expression pattern, causing unexpected results. To solve this, you can use the preg_quote function to escape the delimiter before using it in preg_split. 

// Example of using preg_split with preg_quote to escape the delimiter
$content = "apple,banana,orange";
$delimiter = ",";
$escaped_delimiter = preg_quote($delimiter, '/');
$parts = preg_split('/' . $escaped_delimiter . '/', $content);

print_r($parts);
