The first loop executes correctly. The second and third loops perform incorrect comparisons. In loops two and three, '0' == 'NOLIMIT' evaluates to true when it should be false. Reproduce code: --------------- $arr = array('0' => '$0', '1000' => '$1,000', '2000' => '$2,000', '3000' => '$3,000', 'NOLIMIT' => 'NO LIMIT'); foreach ($arr as $key => $value) { echo "$key : $value $hi\n"; } echo "\n"; foreach ($arr as $key => $value) { if ($key == 'NOLIMIT') { continue; } echo "$key : $value $hi\n"; } echo "\n"; foreach ($arr as $key => $value) { $hi = ($key == 'NOLIMIT' ? 'hi' : ''); echo "$key : $value $hi\n"; } Expected result: ---------------- 0 : $0 1000 : $1,000 2000 : $2,000 3000 : $3,000 NOLIMIT : NO LIMIT 0 : $0 1000 : $1,000 2000 : $2,000 3000 : $3,000 0 : $0 1000 : $1,000 2000 : $2,000 3000 : $3,000 NOLIMIT : NO LIMIT hi Actual result: -------------- 0 : $0 1000 : $1,000 2000 : $2,000 3000 : $3,000 NOLIMIT : NO LIMIT 1000 : $1,000 2000 : $2,000 3000 : $3,000 0 : $0 hi 1000 : $1,000 2000 : $2,000 3000 : $3,000 NOLIMIT : NO LIMIT hi I am using PHP 5.03 and Apache 2.0.53 on Windows XP, service patch 2. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33368&edit=1
