Regex tester
The regex tester is a convenient tool that highlights matching parts in real-time by simply entering a regex pattern and a search string. Equipped with a wealth of sample patterns and a quick reference for metacharacters, it is widely usable from beginners to advanced users.
Character and byte counter
When you enter a string, it will display the number of characters (digits) and the number of bytes in the specified character encoding.
Retrieve a substring from the end in PHP
To extract a substring from the end of a string using PHP's mb_substr function, specify the length of the target string minus the length of the substring as the extraction start position.
Convert kanji to romaji
This tool converts a string of mixed Kanji and Kana characters into Romaji. You can choose from Hepburn, Kunrei, or Nihon systems for the conversion. It can also convert strings composed solely of Hiragana or Katakana.
