// Purpose: Match items between two arrays. Similar to my radiation_onc function.
// ----------------------------------------------------------------------------

//The function arrayitemmatch will display matching items between two arrays.
//It takes two options 1, or 2. Default is 1.
//Option 1 will display the matching items and a blank space for items that do not match.
//Option 2 will display the matching items only.

if ($array2item[$array2itemname1] == $array1itemname) { // If treatment code matches the radiation code.
return "<tr><td>" . $array2item[$array2itemname3] . "</td><td>" . $array2item[$array2itemname2] . "</td><td>" . $array2item[$array2itemname1] . "</td></tr>"; // Return the treatment date and result.
}
}
return "<tr><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td></tr>"; // If no match, return empty.
} elseif ($option == 2) {

return "<tr><td>" . $array2item[$array2itemname3] . "</td><td>" . $array2item[$array2itemname2] . "</td><td>" . $array2item[$array2itemname1] . "</td></tr>"; // Return the treatment date and result.
}
}
// return ""; // If no match, return empty.
