  • $letters = 'भबहगदजडपरकतटचमनवलसयघधझढञफऱखथछठशषणज्ञत्रक्षश्र23456789'; $len = mb_strlen($letters); for ($i = 0; $i< 6;$i++) { $letter = $letters[rand(0, $len-1)]; imagestring($image,9 , 5+($i*30), 20, $letter, $text_color); $word.=$letter; } – Anand Saran Nov 10 '16 at 14:59

You can't safely select a single utf-8 character with $letters[rand(0, $len-1)];, since it's a multi-byte encoding: you just get a single byte. You should use mb_substr instead.

$letter = mb_substr($letters, rand(0, $len-1), 1);
