Hi,

I use the following php version:
      PHP 5.5.3 (cli)
      Zend Engine v2.5.0

In a Interactive mode (php -a), when  I execute any php command nothing happens

echo "Hello World";

The expected result was the Interactive mode execute the php command, in the case print the string  "Hello Word"  on standard output

Actual result:

Result: nothing, the cursor remains blinking and don't execute the php command
