Edit report at https://bugs.php.net/bug.php?id=73125&edit=1 ID: 73125 Updated by: requinix@php.net Reported by: sami dot vento at codeworks dot fi Summary: array declaration shouldn't allow same key multiple times Status: Open Type: Feature/Change Request Package: Arrays related PHP Version: 7.0.11 Block user comment: N Private report: N New Comment: Personally, I would be disappointed to see this implemented as I sometimes use it in place of a long if or ternary, like $value = [ true => "default", // lowest priority $some_condition => "some value", $other_condition => "other value", $final_condition => "final value" // highest priority ][true]; Previous Comments: ------------------------------------------------------------------------ [2018-12-12 09:26:03] daniele dot maggio at dotnext dot it Sorry but I think it's not a bug; it is correct that your value is overwrited since you use a text key, The matter is how you use things. ------------------------------------------------------------------------ [2016-09-20 11:20:05] sami dot vento at codeworks dot fi Description: ------------ Defining array with single clause should check duplicate keys and at least warn user. Current implementation just takes last defined value for key. Test script: --------------- $a = array('a'=>3, 'a'=>4); var_dump($a); Expected result: ---------------- notice, warning or error Actual result: -------------- array(1) { ["a"]=> int(4) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73125&edit=1
