Parse Errors in evaluated Code

Even though the need for eval() usually points out a design flaw, PHP’s handling of parse errors in evaluated code has been improved in PHP 7.

A parse error encountered in code that is to be executed via eval() will throw a ParseError, exactly like PHP would do for included or required code.

try {
    eval('parse error');
    echo 'next in line';
} catch (ParseError $parseError) {

The main difference compared to included code is that PHP 5 continued to run even if the execution of the eval() failed. Since PHP 7 throws a ParseError, the line containing the echo statement in the example above will never be reached. If that line were to do some error handling or logging, you would need to adjust it for PHP 7 by moving that line into the catch block.
