note 107336 added to function.count-chars

If you have problems using count_chars with a multibyte string, you can change the page encoding. Alternatively, you can also use this mb_count_chars version of the function. Basically it is mode "1" of the original function. <?php /** * Counts character occurences in a multibyte string * @param string $input UTF-8 data * @return array associative array of characters. */ function mb_count_chars($input) { $l = mb_strlen($input, 'UTF-8'); $unique = array(); for($i = 0; $i < $l; $i++) { $char = mb_substr($input, $i, 1, 'UTF-8'); if(!array_key_exists($char, $unique)) $unique[$char] = 0; $unique[$char]++; } return $unique; } $input = "Let's try some Greek letters: αααααΕεΙιΜμΨψ, Russian: ЙЙЫЫЩН, Czech: ěščřžýáíé"; print_r( mb_count_chars($input) ); //returns: Array ( [L] => 1 [e] => 7 [t] => 4 ['] => 1 [s] => 5 [ ] => 9 [r] => 3 [y] => 1 [o] => 1 [m] => 1 [G] => 1 [k] => 1 [l] => 1 [:] => 3 [α] => 5 [Ε] => 1 [ε] => 1 [Ι] => 1 [ι] => 1 [Μ] => 1 [μ] => 1 [Ψ] => 1 [ψ] => 1 [,] => 2 [R] => 1 [u] => 1 [i] => 1 [a] => 1 [n] => 1 [Й] => 2 [Ы] => 2 [Щ] => 1 [Н] => 1 [C] => 1 [z] => 1 [c] => 1 [h] => 1 [ě] => 1 [š] => 1 [č] => 1 [ř] => 1 [ž] => 1 [ý] => 1 [á] => 1 [í] => 1 [é] => 1 ) ?> ---- Server IP: 147.32.160.17 Probable Submitter: 109.80.205.124 ---- Manual Page -- http://www.php.net/manual/en/function.count-chars.php Edit -- https://master.php.net/note/edit/107336 Del: integrated -- https://master.php.net/note/delete/107336/integrated Del: useless -- https://master.php.net/note/delete/107336/useless Del: bad code -- https://master.php.net/note/delete/107336/bad+code Del: spam -- https://master.php.net/note/delete/107336/spam Del: non-english -- https://master.php.net/note/delete/107336/non-english Del: in docs -- https://master.php.net/note/delete/107336/in+docs Del: other reasons-- https://master.php.net/note/delete/107336 Reject -- https://master.php.net/note/reject/107336 Search -- https://master.php.net/manage/user-notes.php
