But doesn't work with different PHP versions. Test script: --------------- class AdwordsCityComponent { private $adwordsCityObj = array( 1000010=>"Abu Dhabi,Abu Dhabi,United Arab Emirates", 1000011=>"Ajman,Ajman,United Arab Emirates", // ~80000 more rows.... 9062586=>"Bratislava Region,Slovakia", 9062587=>"Trnava Region,Slovakia"); /** * getCityNameById */ public function getCityNameById($adwordsCityObjId) { $cityName = "Unspecified"; $cityArray = $this->adwordsCityObj; echo "Total array count : "; echo count($this->adwordsCityObj); if(array_key_exists($adwordsCityObjId, $cityArray)){ $cityName = $cityArray[$adwordsCityObjId]; } return $cityName; } } full source code & php -i output at: https://www.dropbox.com/s/83sd89t58xn7kz2/PhpArrayIssue.zip?dl=0 Expected result: ---------------- // PHP 5.5 works fine administratorsmac$ /usr/bin/php testAds.php Total array count : 64455 Bremerton,Washington,United States Actual result: -------------- // PHP 5.6 gives wrong count & result administratorsmac$ php testAds.php Total array count : 31687 Unspecified ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73321&edit=1
