you can write the function in a separate file  say common-functions php  and include it wherever needed   function getEmployeeFullName  employeeId       Write code to return full name based on  employeeId     You can include common-functions php in another file as below   include  common-functions php    echo  Name of first employee is     getEmployeeFullName 1     You can include any number of files to another file  But including comes with a little performance cost  Therefore include only the files which are really required
