php uses the Gd library to add garbled text watermarks Problems and solutions

Recently a project underwent server migration. After deployment, it was discovered that one of the functions of adding watermark text to pictures had garbled problems. Confirm that there is no problem with the function code, and at the same time the project code They all use UTF-8 encoding, and there is no encoding problem. We also checked and ruled out the possibility of problems with the font files. After consulting the information, we finally found a PHP compilation parameter --enable-gd-jis-conv.

--enable-gd-jis-conv:

If the --enable-gd-jis-conv option is enabled when PHP is compiled, then non-ASCII characters (such as Chinese characters, Pinyin, Greek text and arrows) will be regarded as EUC-JP encoding, eventually causing normal Chinese to become garbled

Solution:

1. Remove the --enable-gd-jis-conv option and re- Compile php

2. Convert characters to html entities

mb_convert_encoding ('Test', 'HTML-ENTITIES', 'UTF-8');
