how to ignore first loop and continue from second in foreach?

Question

I use foreach loop but it always gives an wierd result in the first but others are fine so i want to remove 1st loop and continue from 2nd...

My code is

foreach($doc->getElementsByTagName('a') as $a){
foreach($a->getElementsByTagName('img') as $img){
   echo $a->getAttribute('href');
   echo $img->src . '<br>';
}
}

Answer 1

$counter = 0;

foreach($doc->getElementsByTagName('a') as $a){
foreach($a->getElementsByTagName('img') as $img){

   if ($counter++ == 0) continue;

   echo $a->getAttribute('href');
   echo $img->src . '<br>';
}
}

Answer 2

The simplest way I can think of in order to skip the first loop is by using a flag

ex:

 $b = false;
 foreach( ...) {
    if(!$b) {       //edited for accuracy
       $b = true;
       continue;
    }
 }
