“Strict Standards”-Error after PHP-Update

Question

i need to update my php-version. The site still runs with 5.2. The problem is every newer version results in an error.

Errors at php version 5.3+:

• Strict Standards: Only variables should be passed by reference in /xxx/xxx on line 52
• Strict Standards: Only variables should be passed by reference in /xxx/xxx on line 84
• Strict Standards: Only variables should be passed by reference in /xxx/xxx on line 85

Here are the affected lines:

52: $this->pathToModule = realpath ( self::$MODULE_DIRECTORY .     DIRECTORY_SEPARATOR . Filter::instance( $tmpStr = $name )->toLowerCase() );
84: $backendClassName   = Filter::instance($tmp = $this->name)->camelize() . self::BACKEND_FILESUFFIX;
85: $frontendClassName  = Filter::instance($tmp = $this->name)->camelize() . self::FRONTEND_FILESUFFIX;

Has anyone an idea where the problem could be?

Thank you in advance,

Marvin

Answer 1

So set your temps as variables before the Filter call rather than assigning them within the argument:

Change

$frontendClassName  = Filter::instance($tmp = $this->name)->camelize() . self::FRONTEND_FILESUFFIX;

to

$tmp = $this->name;
$frontendClassName  = Filter::instance($tmp)->camelize() . self::FRONTEND_FILESUFFIX;

etc

But watch out in case $tmp is modified by the call
