For those of you landing here but searching how to break out of a loop that contains an include statement use return instead of break or continue.

<?php

for ($i=0; $i < 100; $i++) { 
    if (i%2 == 0) {
        include(do_this_for_even.php);
    }
    else {
        include(do_this_for_odd.php);
    }
}

?>

If you want to break when being inside do_this_for_even.php you need to use return. Using break or continue will return this error: Cannot break/continue 1 level. I found more details here

A safer way to approach breaking a foreach or while loop in PHP is to nest an incrementing counter variable and if conditional inside of the original loop  This gives you tighter control than break  which can cause havoc elsewhere on a complicated page   Example      Setup a counter  ImageCounter   0      Increment through repeater fields while   condition       ImageCounter           Only print the first while instance    if   ImageCounter    1        echo  It worked just once            Close while statement endwhile

if is not a loop structure  so you cannot  quot break out of it quot   You can  however  break out of the foreach by simply calling break  In your example it has the desired effect   device    quot wanted quot   foreach  equipxml as  equip         current device    equip- gt xpath  quot name quot        if    current device 0      device                found a match in the file                      nodeid    equip- gt id              will leave the foreach loop and also the if statement         break          some function       never reached            another function        not executed after match break     Just for completeness for others that stumble upon this question looking for an answer   break takes an optional argument  which defines how many loop structures it should break  Example  foreach  array  1   2   3   as  a        echo  quot  a  quot       foreach  array  3   2   1   as  b            echo  quot  b  quot           if   a     b                 break 2      this will break both foreach loops                     echo  quot    quot       never reached    echo  quot   quot    Resulting output   1 3 2 1
