Ticket #48074: 48074-src-Remove-work-arounds-for-spl_object_hash.patch

File 48074-src-Remove-work-arounds-for-spl_object_hash.patch, 3.4 KB (added by jrf, 5 years ago)

[src] Remove work-arounds for spl_object_hash() - The sp_object_hash() function was introduced in PHP 5.2.0 and as of PHP 5.3, the PHP SPL extension can no longer be disabled, so these work-arounds are no longer needed. See: ​https://www.php.net/manual/en/function.spl-object-hash.php
