Bug #10770: . (concatenation) preceeds mathematical operations in order of execution

From: vitaliyf@gameaholic.com Operating system: Linux PHP version: 4.0.5 PHP Bug Type: Feature/Change Request Bug description: . (concatenation) preceeds mathematical operations in order of execution <? $i=10; print "hello " . $i-2 . " world"; ?> will output: -2 world ("hello " . $i is evaluated into "hello 10", then 2 is subtracted (by casting "hello 10" into a 0, then subtracting 2). Then "world" is appened, thus giving us "-2 world") I think this might be way counter-intuitive to what should be happening: - (or all other operations) should be avaluated first, and concatenation last, producing "hello 8 world". Or how about this example, which definately can confuse some people: print "Hello is less than " . 1+strlen('hello') . " characters long."; Workaround: use () to arrange things to be executed in proper order but that might not be obvious for someone who doesn't know about this situation.
