i use Yii2 , OS ubuntu 16.0.4 , PHP7 , Apache , MySql
i think this problem from php7
how to enable or install json_encode for php and ctype_digit for mysql?
i have this error:
Call to undefined function yii\web\json_encode()
Call to undefined function yii\db\mysql\ctype_digit()
phpInfo:
Configuration File (php.ini) Path /etc/php/7.0/apache2
Loaded Configuration File /etc/php/7.0/apache2/php.ini
Scan this dir for additional .ini files /etc/php/7.0/apache2/conf.d
Additional .ini files parsed /etc/php/7.0/apache2/conf.d/20-mbstring.ini
about json i only find this on phpinfo:
JSON Jakub Zelenka, Omar Kilani, Scott MacVicar
Enable json encode in php.ini file in /etc/php/php.ini. In this case, you'd need to uncomment the 'extension=json.so' line.
