copied!<p>hey guys was hoping you could help me out.</p> <p>I am required to make a website coded in php+codeigniter to work with utf 16 charset.</p> <p>So to convert it,</p> <p>I have converted the database.php settings to:</p> <pre><code>$db['default']['char_set'] = 'utf16'; $db['default']['dbcollat'] = 'utf16_unicode_ci'; </code></pre> <p>I have made the config.php settings to:</p> <pre><code>$config['charset'] = 'UTF-16'; </code></pre> <p>That seemed to solve the problem that was caused when outputing data, however I now have a new problem.</p> <p>My form validation checks have started failing, particular the length one.</p> <p>i.e when debugging I found that it was taking admin@admin.com as length 7 with the mb_strlen function.</p> <p><em><strong>note that it was working properly before the charset change! problem started after charset change.</em></strong></p> <hr> <p>update: turns out if you do mb_strlen($str,'utf-8') i get the correct answer, meaning that I am getting utf-8 encoded strings from the form.</p> <hr> <p>changing the min_length function from </p> <pre><code>public function min_length($str, $val) { if (preg_match("/[^0-9]/", $val)) { return FALSE; } if (function_exists('mb_strlen')) { return (mb_strlen($str) < $val) ? FALSE : TRUE; } return (strlen($str) < $val) ? FALSE : TRUE; } </code></pre> <p>to this:</p> <pre><code>public function min_length($str, $val) { if (preg_match("/[^0-9]/", $val)) { return FALSE; } if (function_exists('mb_strlen')) { echo $str,"<br/>"; echo mb_strlen($str),"<br/>"; echo $val;die(); return (mb_strlen($str) < $val) ? FALSE : TRUE; } return (strlen($str) < $val) ? FALSE : TRUE; } </code></pre> <p>I get the following output:</p> <pre><code>admin@admin.com 7 8 </code></pre> <p>i.e it is taking admin@admin.com as length 7!</p>
