Trying to get rid of an error message

I am trying to set up a job search engine using careerjet's API. Everything is working fine except when the careerjet's database doesn't have jobs available for a particular query the error_log writes and posts this message:

Warning: Invalid argument supplied for foreach() in /home1/fastjobs/public_html/index.php on line 117

In my case line 117 is this one in the index page:

foreach( $jobs as $job ){

My question is is there a way to make it say a specific error message instead of a generic one when no jobs are available. Something like: Sorry, no jobs were found.

Any help will be appreciated.

This is the entire snippet:

Code:

---

      $jobs = $result->jobs ;

          foreach( $jobs as $job ){
         
            $counter++;
         
            echo "<div class='job'>";
            echo "<span class='title'><a target='_blank' href='". $job->url . "'>" . $job->title . "</a></span>";
            echo "<div class='location'>" . $job->locations . "</div>";
            echo "<div class='company'>" .$job->company . "</div>";
            echo "<div class='salary'>" . $job->salary . "</div>";
            echo "<div class='date'>" . $job->date . "</div>";
            echo "<div class='description'>" . $job->description . "</div>";
            echo "</div>";
          }

---

Something like:

PHP Code:

---

      $jobs = $result->jobs ;
    if(!$jobs or 0 == count($jobs)){
        echo "My custom Error Message - There ain't no Jobs Dude!";
    } else
          foreach( $jobs as $job ){
           
            $counter++;
           
            echo "<div class='job'>";
            echo "<span class='title'><a target='_blank' href='". $job->url . "'>" . $job->title . "</a></span>";
            echo "<div class='location'>" . $job->locations . "</div>";
            echo "<div class=' . . .
