``` I'm trying to remove the `[INST]` and `<>` tags from the content. I've tried using `str_replace` but it seems that the `<<` and `>>` characters are being replaced as well. Here's what I've tried: ``` $content = str_replace(array('[INST]', '<>'), '', $content); ``` How can I remove just the `[INST]` and `<>` tags without affecting the `<<` and `>>` characters that are part of the tags? ## Answer (3) You can use a regular expression with `preg_replace` to match the tags more precisely: ``` $content = preg_replace('/<\[\w+\]>|<>/', '', $content); ``` This will replace `[INST]` and `<>` while preserving the `<<` and `>>` characters when they are not part of the tags. The pattern `<\[\w+\]>` matches a literal `[` followed by any word characters (including underscore) and a literal `]` enclosed in `<` and `>`. The `\w` in the character class matches any word character (letters, digits, or underscores). ## Answer (1) You can use `preg_replace` with a regular expression that matches the exact pattern of the tags you want to remove, including the angle brackets. Here's how you can do it: ``` $content = preg_replace('/<(\[INST\]|<>)>/', '', $content); ``` This regular expression will match the entire tag `<[INST]>` or `<>>` and replace it with an empty string. The parentheses `()` create a capturing group, and the escaped angle brackets `<` and `>` match the angle brackets literally. The `|` operator allows the regex to match either `[INST]` or `<>` inside the angle brackets. ## Answer (1) You can use `preg_replace` with a regular expression to match the tags exactly.
