Edit report at https://bugs.php.net/bug.php?id=73321&edit=1 ID: 73321 Updated by: requinix@php.net Reported by: pmakkar at bayatree dot com -Summary: array count shows wrong value +Summary: array count shows wrong value when defined inside class Status: Open -Type: Bug +Type: Documentation Problem -Package: Arrays related +Package: Class/Object related Operating System: Mac OS X 10.11 PHP Version: 5.6.26 Block user comment: N Private report: N New Comment: Duplicate of bug #68057. Unfortunately this cannot be fixed in 5.6 due to binary BC, but you can work around it by defining the array outside of the class (and then somehow getting it into the class, if you wish). I feel like this should be documented but I'm not sure where. OOP Changelog? Maybe in the 7.0 migration docs too? http://php.net/manual/en/language.oop5.changelog.php http://php.net/manual/en/migration70.php Previous Comments: ------------------------------------------------------------------------ [2016-10-14 12:12:23] pmakkar at bayatree dot com // PHP 5.5 works fine administratorsmac$ /usr/bin/php testAds.php Total array count : 86459 Bremerton,Washington,United States Actual result: -------------- // PHP 5.6 gives wrong count & result administratorsmac$ php testAds.php Total array count : 20923 Unspecified Corrected actual results........ ------------------------------------------------------------------------ [2016-10-14 11:57:50] pmakkar at bayatree dot com Description: ------------ I've a large PHP array (~85000 elements) in a class, on php 5.5 (/usr/bin/php) on my system (mac OS X 10.11) it works as expected (count ~ 86459), but on same system with php 5.6 (php), it fails to lookup few keys because of wrong count (count ~ 20923). testAds.php prints city name corresponding to ID 1027519, which exists in 2nd file AdwordsCityComponent.php. But doesn't work with different PHP versions.
