php foreach with counter loop within it

Question

I have a lot of code but basically its a foreach loop with values collected and $i is the dynamic number.

I want to get a bunch of attachments from a json and have following inside the foreach

<?php

$i=0;
foreach($attribs->contentblocks->add_to_content as $count) { 

if($attribs->contentblocks->add_to_content[$i]=='3') { 

// other code goes here

?>

<?php for($a = 1; $a < 30; ++$a){ ?>

<?php echo $attribs->contentblocks->blockfile[$a][$i];?>

<?php } ?>

<?php $i++; }} ?>

But... it wont work. If i replace [$a] with an actual number like 1 or 2 or 3 it works.

How do i add the dynamic $a number into that line to work with my $i as well?

Cheers John

what do you mean foreach loop? thats a for loop, and on our side, there is nothing wrong with it — Kevin

<?php echo $attribs->contentblocks->{'blockfile'.$a}[$i]; ?>

If you want $i as incremented variable. You can achieve this by doing:

<?php
$i = 0;
 for($a = 1; $a < 30; ++$a){ ?>

<?php echo $attribs->contentblocks->blockfile[$a][$i];?>

<?php $i++; } ?>

$i is already set as 0 then 1 then 2 - depends on how many blocks there are. The $a is the one that i need to work as it is a loop inside the foreach for $i
