Handle PHP build error

Question

I am developing a web system in PHP with MVC and Smarty. But I am having the following problem. My system when entering an Exception it automatically opens a call already with the error (inserts a value in a table responsible for the call). The problem starts there, build error does not enter any Exception. For example:

    <?php
        $a = 1;
        a
        echo $a;
    ?>

Note that there is a loose letter there, I get the following message:

Parse error: syntax error, unexpected 'echo' (T_ECHO) in...

I already use these two functions to catch PHP errors:

set_exception_handler('myException');
set_error_handler('myHandler',E_ALL);

I have already implemented classes that inherit the class Exception to handle errors. Nothing else to solve this problem.
