构建多参数查询字符串

I am trying to build a multi-param query string, but I get a 500 error when I try to run this in production. To me it get's quite difficult knowing where to place a ' and a " but I am sure the more I php code the easier it will become.

Below is my syntax - what should be changed so that this becomes valid syntax? (all variables are declared in the script)

<td><a href="Test.php?emp='.$Row['Employee Name'].
'"&hiredate=" . $hiredate 
'"&terminationdate=" . $termdate 
'">'.$Row['Number Of Abscences'].'</a></td>

I suggest to use sprintf/vsprintf:

vsprintf('<td><a href="Test.php?emp=%s&hiredate=%s&terminationdate=%s">%s</a></td>',[$Row['Employee Name'],$hiredate,$termdate,$Row['Number Of Abscences']])

Is much more readable and easiet to maintain \
