PHP simple HTML DOM parser not work

Question

I have this problem

This it works:

foreach($inzeraty->find("a") as $nazov)
    { 
      echo $nazov."<br />"; 
    }

but I need just first tag "a" and this NOT work:

foreach($inzeraty->find("a", 0) as $nazov)
    { 
      echo $nazov."<br />"; 
    }

Error: Invalid argument supplied for foreach()

Answer 1

You may try:

$first_anchor = $inzeraty->find("a", 0);
echo $first_anchor;

From the docs: // Find (N)th anchor, returns element object or null if not found (zero based) It returns one only element, not an array, so you cannot loop over it.

Answer 2

将其视为数组， echo $inzeraty->find("a")[0];

Answer 3

i will suggest to count and display the first. as the following:

$i = 0;
foreach($inzeraty->find("a") as $nazov)
{ 
  $i++;
  if($i == 1)
    echo $nazov."<br />"; 
}
