executing foreach loop only once [closed]

Question

As we know foreach loop will execute till condition does not become false. I want to execute it only once.

$i=0;
foreach($html->find('img') as $element) 
{    

       if($i!=0)  
          break;
       $logo= $element->src . '<br>';
       $i++;
}

Is there any other solution for this? like foronce in place of foreach?

As we know foreach loop will execute till condition does not become false.

A foreach loop will execute once for every item of the container unless a return or break condition is defined within the foreach block.

I want to execute it only once.

Loops that executes once are called "don't use a loop in the first place". Here's your example fixed:

$logo = $html->find('img')[0]->src . '<br>';
