停止并继续foreach循环

Question

I've got a page of HTML blocks and they're all the same. As a result, I'm using a foreach loop to duplicate the content (up to 6 times). However, in the middle of the page, I need to break out of the loop, do something else, then continue. It would look like this:

BLOCK 1
BLOCK 2
BLOCK 3

(jump out of loop)

BLOCK 4
BLOCK 5

I've tried using an if statement :

if on `BLOCK 3`: 
insert some content afterwards

But ideally I'd like to stop it, then start it (as the content being inserted is in no way related).

In theory I could do this with two foreach loops (one on each side), but that in my mind, seems unnecessary.

Is there a way to completely jump out of the loop, then return (once some HTML has been written, or a function executed)?

I'm a novice so any help or advice would be great.

Answer 1

Well do exactly that then:

for (;;) {
    if (needsSpecialThreatment) {
        doSmthSpecial;
        continue;
    }
    doUsualStuff;
}

( continue is a PHP keyword for loops, not pseudocode here)

Answer 2

You're overthinking this. Something like this should do what you need:

<?php
    $temp = 0;
    foreach($blocks_of_HTML as $block_of_HTML){
        $temp += 1
        if($temp = 3){
            doSomethingElse();
        }

        //Code to write HTML Block
    }
?>

If all you're needing to do is do something else, just keep track of a counter variable and execute a function to do whatever else you need to do and then allow the loop to continue as expected.
