When you work in PHP Symfony, many are the chances to see a statement like this
<?php echo link_to(__(‘String title’), $internal_uri, array(‘target’ => ‘_blank’, ‘title’ => __(‘String title’)) );
Ok! lets not worry about $internal_uri here.
Leaving that out, take a closer look at the above statement. there is a link_to() function and its out put is echo’d . Other than that there is a weird __() thingy!
Does it look like a operator? NO! Its a function in symfony that takes care of translation.
what does it translate? The string you pass Eg: In the snippet, __() would look for translations of the string ‘string title’
