When we recently upgraded from 5.3.8 to 5.4, a slew of error messages appeared. See the test script below. We've tried to minimize it, but any changes do not cause the error to trigger. Changing the variable name "region_id" to "egion_id" results in 90. Changing the variable name "region_id" to "tegion_id" causes the same error. Changing the variable name "discipline" to "isciplined" results in 92. Changing the value assigned to region_id from 1 to 2 results in 92. Changing the value assigned to region_id from 1 to 4 results in an error. Test script: --------------- $array = array( 'region_id' => 1, 'discipline' => 23, 'degrees' => array(), 'country_id' => 27 ); $serialized = serialize($array); $deflated = gzdeflate($serialized, 9); $inflated = gzinflate($deflated); echo strlen($inflated); Expected result: ---------------- Expected: 92 Actual result: -------------- Warning: gzinflate(): data error in D:\Web\Projects\Bench\index.php on line 13 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61287&edit=1
