When applied to a 518K JSON payload, the preg_replace_callback() function fails. I could likely address this by modifying the pcre backtrack/recursion limits on my server.\r\n\r\nYour users may trigger a similar edge case only if they have a large post_content field - unlikely, but remotely possible and a nasty gremlin to detect as there are no errors to explain the missing output.\r\n\r\nI would submit a patch if/when I raise my regex game.\r\n","author":{"url":"https://github.com/deltafactory","@type":"Person","name":"deltafactory"},"datePublished":"2019-01-18T17:46:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/10/force-https/issues/10"}
