Incompatible PHP version
If your installation shows signs of PHP version incompatibility, such as
- “CSPRNG fucntinons not available” exception
- various fatal Parse errors in Mpdf codebase
make sure both your PHP version in console and in the server environment is supported. Checking phpinfo(); often
does not suffice, try inserting var_dump(PHP_VERSION); die; right before your mPDF code to find actual PHP version
used with mPDF.
PHP version mismatches in cli
It is possible your server PHP version differs from your default cli version. Verify your cli PHP version with php -v and/or
use an absolute path to the PHP executable when calling composer.
