From: cmbecker69 at gmx dot de Operating system: WIN32 PHP version: 5.4.19 Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:uniqid(null, false) should guarantee unique identifier
Description: ------------ >From looking at the sources[1], it occurs to me that uniqid(null, false) doesn't *guarantee* to return a unique identifier on WIN32, because usleep(3) is skipped. As usleep() is implemented as PHP userland function since PHP 5.0.0[2], it seems to be reasonable and possible to add the equivalent to usleep(3) there. As far as I can tell, this won't introduce any BC issues, so the change might be done for PHP 5.4.x. Please note that this is related to #37106[3], but helly's comment doesn't seem to fit to the current sources.
