Function TRUE/FALSE return values
Most internal functions have been rewritten so they return TRUE
when successful and FALSE when failing, as opposed to 0 and -1 in
PHP/FI 2.0, respectively. The new behaviour allows for more
logical code, like $fp = fopen("/your/file") or
fail("darn!");. Because PHP/FI 2.0 had no clear rules
for what functions should return when they failed, most such
scripts will probably have to be checked manually after using the
2.0 to 3.0 convertor.
Example F.9. Migration from 2.0: return values, old code
$fp = fopen($file, "r");
if ($fp == -1);
echo("Could not open $file for reading<br />\n");
endif; ?>
Example F.10. Migration from 2.0: return values, new code
$fp = @fopen($file, "r") or print("Could not open $file for reading<br />\n"); ?>
