Description:
------------
The tempnam function sets the access permissions mode of the file it creates to 0600.  This behavior is undocumented and is different from the behavior of fopen, which sets the access permissions mode to 0644.

tempnam's behavior is therefore either a bug or an undocumented "feature".  If you consider this to be a "feature" and not a bug, please reclassify this bug report as a documentation request.

The revelant source files are:
  ext/standard/file.c
  main/php_open_temporary_file.c

'man mkstemp' is also interesting reading, as mkstemp behaves differently in different versions of glibc.

Thank you!


Reproduce code:
---------------
<?php

fopen ('test.txt', 'w');
tempnam ('.', 'test-');

print '<pre>';
print `ls -ln test.txt test-*`;
print '</pre>';

?>


Expected result:
----------------

Actual result:
