You're using single quotes around both the code, and also around the strings. I'm not sure exactly what's happening, but PHP is telling you that it is encountering a "undefined constant imagettfbbox". Also, returning a boolean doesn't show any output. For debugging, try doing var_dump instead, and use double-quotes for the strings: php -r 'var_dump( function_exists("imagettfbbox") && function_exists("imagettftext"));'The point is there's no "freeetype support", php -r 'var_dump(gd_info());' array(13) { ["GD Version"]=> string(5) "2.2.5" ["FreeType Support"]=> >>> bool(false) ["GIF Read Support"]=> bool(true) ["GIF Create Support"]=> bool(true) ["JPEG Support"]=> bool(true) ["PNG Support"]=> bool(true) ["WBMP Support"]=> bool(true) ["XPM Support"]=> bool(true) ["XBM Support"]=> bool(true) ["WebP Support"]=> bool(true) ["BMP Support"]=> bool(true) ["TGA Read Support"]=> bool(true) ["JIS-mapped Japanese Font Support"]=> bool(false) }the point is there's no freetype support, php -r 'var_dump(gd_info());' array(13) { ["GD Version"]=> string(5) "2.2.5" ["FreeType Support"]=> !!! bool(false) ["GIF Read Support"]=> bool(true) ["GIF Create Support"]=> bool(true) ["JPEG Support"]=> bool(true) ["PNG Support"]=> bool(true) ["WBMP Support"]=> bool(true) ["XPM Support"]=> bool(true) ["XBM Support"]=> bool(true) ["WebP Support"]=> bool(true) ["BMP Support"]=> bool(true) ["TGA Read Support"]=> bool(true) ["JIS-mapped Japanese Font Support"]=> bool(false) }
