check a variable after EACH function

This might seem silly but here's what I'm trying to do Suppose I have some kind of check variable - say for example $abort_now. Or it could be a function. Something to be evaluated to a value. I want to execute a block of statements, but after EACH statement executes, check the value of $abort_now and if it is true, break; out of the block. Here's an example do { do_something(); do_something_else(); do_another_thing(); do_yet_another_thing(); and_keep_doing_things(); } while ($abort_now != 1); What I want to happen is for each statement to execute, and keep looping around, until the $abort_now variable is set to 1. Now, suppose any one of the statements in that block may cause $abort_now to become 1. If that happens, I want the block to stop executing immediately and not continue executing further statements. For example, do_another_thing() causes $abort_now to equal 1. I do not want do_yet_another_thing or keep doing things to execute. I want the loop to stop right there. The only way I can think of doing it is to insert a check after each statement: do { do_something(); if ($abort_now == 1) { break; } do_something_else(); if ($abort_now == 1) { break; } do_another_thing(); if ($abort_now == 1) { break; } do_yet_another_thing(); if ($abort_now == 1) { break; } and_keep_doing_things(); if ($abort_now == 1) { break; } } while (TRUE); This might work for 2 or 3 statements but imagine a block of say 15 statements. Having a check after each one would look ugly, and cause trouble if the condition needed to be changed or if I instead decided to check it, say, against a function. So is this possible to do with built in code? or am I stuck with having to put a check after each statement in? thanks fm
