The manual says:
> In PHP 4, eval() returns NULL unless return() is called in the evaluated code...

This is not true. PHP returns FALSE if a fatal error occurs.

This is very important especially for CLI/SAPI applications which must often catch fatal errors and propogate them with exit(1).

Reproduce code:
// FILE: test/test.php
echo "Non-Fatal Error Returns: ";
if($x===FALSE) echo "FALSE\n";
if(is_null($x)) echo "NULL\n";
echo "Fatal Error Returns: ";
if($x===FALSE) echo "FALSE\n";
if(is_null($x)) echo "NULL\n";

Expected result:
$ php test/test.php 
Non-Fatal Error Returns: NULL
PHP Parse error:  parse error in /usr/local/apache/htdocs/common/php/xmake_org/xobj/test/test.php(6) : eval()'d code on line 1
Fatal Error Returns: FALSE

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"In case of fatal error in evaluated code, eval returns FALSE."
