Jerred121 Posted February 7, 2011 Share Posted February 7, 2011 OK, i have a function that compares values and returns the results, regardless of case, ie: Interfacility Transfer = INTERFACILITY TRANSFER here is the function: function fncResult ($expVal, $actVal) { $negNulls=array("-5","-10","-15","-20","-25"); if (!in_array($expVal, $negNulls)) { if(strtolower($expVal)==strtolower($actVal)) { echo " <td class='match' title='The values match.'>Match</td> </tr>"; } else { echo " <td class='notMatch' title='The values do not match.'>Not Match<br />No Match</td> </tr>"; } } else { echo " <td class='null' title='The value in the XML was a negative null.'>Negative Null</td> </tr>"; } } It works about 99% of the time except when it comes to this: //--Type of service requested echo " <tr> <td>E02_04</td> <td>Type of Service Requested</td> <td>36. <Nature of Call></td> <td>$fldServReq</td> <td>".fncGrabNemsis("E02_04",$fldServReq,$local)."</td> <td>".fncIsSet($CZ_E02_04[1])."</td>"; fncResult(fncGrabNemsis("E02_04",$fldServReq,$local),fncIsSet($CZ_E02_04[1])); Although it looks more complicated, it really is just a strtolower($expVal)==strtolower($actVal), comparison. When I echo the values being compared, I get: "interfacility transfer" and "interfacility transfer" and "No Match"... WTF? Could it be because the first value is coming from a XML (UTF- and the second is from a DB (?) Edit: NM, that can't be the problem. I have no idea what to do and am incredibly frustrated since this a simple task. Thanks for any help!

Psycho Posted February 7, 2011 Share Posted February 7, 2011 Look at the HTML code. Are there any leading/trailing spaces or other white-space characters. Is the space in one value the space character and an in the other? Also, if you are comparing strings you can use strcasecmp() to do a case-insensitive comparison without using strtolower(). Try the following to see what you get function fncResult ($expVal, $actVal) { //Set default values $class = 'null'; $title = 'The value in the XML was a negative null.'; $text = 'Negative Null'; // $negNulls=array("-5","-10","-15","-20","-25"); if (!in_array($expVal, $negNulls)) { if(strcasecmp($expVal, $actVal)===0) { $class = 'match'; $title = 'The values match'; $text = 'Match'; } else { $class = 'notMatch'; $title = 'The values do not match.'; $text = 'No Match: expVal: ['.htmlspecialchars($expVal).'], actVal: ['.htmlspecialchars($actVal).']'; } } echo "<td class=\"{$class}\" title=\"{$title}\">{$text}</td>\n"; echo "</tr>\n"; } Link to comment https://forums.phpfreaks.com/topic/226991-strtolowerastrtolowerbmatch-me-wtf/#findComment-1171131 Share on other sites More sharing options...
Jerred121 Posted February 7, 2011 Author Share Posted February 7, 2011 strcasecmp returned even worse results (it failed on all my ints) here is what the html looks like: <tr> <td>E02_04</td> <td>Type of Service Requested</td> <td>36. <Nature of Call></td> <td>40</td> <td>Interfacility Transfer</td> <td>INTERFACILITY TRANSFER</td> <td class='notMatch' title='The values do not match.'>Not Match<br />interfacility transfer <br />interfacility transfer</td> </tr> No extra spaces...

Jerred121 Posted February 7, 2011 Author Share Posted February 7, 2011 Solved - You were on to something with the whitespace - I threw a trim() inside the strtolower() and it works, thanks!
