How to add a loop inside a variable php-CodePudding

I have to use a foreach loop inside a variable in php but Im not sure of the right syntax. This is what Ive tried but it shows an error(Parse error: syntax error, unexpected 'foreach' (T_FOREACH))

 $doctor = foreach($doctor->find_all() as $d){
      echo '<td>'.$d->getName().'</td>';
      echo '<td>'.$d->getEmail().'</td>';
      echo '<td>'.$d->getPhone().'</td>';
      echo '<td>'.$d->getGender().'</td>';
      echo '<td>'.$d->getSpecialist().'</td>';
      echo '<td><a href="../doctor/updatedoc.php"><i ></i></a></td>';
      echo  '<td><a href=""><i ></i></a></td>';
    };

You can't do $doctor = foreach(...

That's not correct PHP syntax.

It's not completely clear to me what you're trying to achieve (aside from outputting some HTML), but start by removing the variable assignment:

foreach($doctor->find_all() as $d) {
      echo '<td>'.$d->getName().'</td>';
      echo '<td>'.$d->getEmail().'</td>';
      echo '<td>'.$d->getPhone().'</td>';
      echo '<td>'.$d->getGender().'</td>';
      echo '<td>'.$d->getSpecialist().'</td>';
      echo '<td><a href="../doctor/updatedoc.php"><i ></i></a></td>';
      echo  '<td><a href=""><i ></i></a></td>';
};

You cannot assign loop on variable or with the echo instead you can direct save the data to variable inside the loop

$doctor = "";
foreach($doctor->find_all() as $d){
      $doctor .='<td>'.$d->getName().'</td>';
      $doctor .='<td>'.$d->getEmail().'</td>';
      $doctor .='<td>'.$d->getPhone().'</td>';
      $doctor .='<td>'.$d->getGender().'</td>';
      $doctor .='<td>'.$d->getSpecialist().'</td>';
      $doctor .='<td><a href="../doctor/updatedoc.php"><i ></i></a></td>';
      $doctor .='<td><a href=""><i ></i></a></td>';
    };

use anonymous function (lambda, etc.) to assign into variable
