Error:
Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 3: parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xE7 0x61 0x69 0x73
XML from database (output from view source in FF):
<?xml version="1.0" encoding="UTF-8" ?><audit><audit_detail>
<fieldname>role_fra</fieldname>
<old_value>Role en français</old_value>
<new_value>Role ç en français</new_value>
</audit_detail></audit></xml>
If I understand correctly, the error is related to the first ç encoded in the old_value tag. To be precise, the error is related to this based on the bytes: "çais" ?
Here's how I load the XML:
$xmlData = simplexml_load_string($ed['updates'][$i]['audit_data']);
The I loop through using this:
foreach ($xmlData->audit_detail as $a){
//code here
}
The field in the database is of data type text and is set utf8_general_ci.
My function to create the audit_detail stubs:
function ed_audit_node($field, $new, $old){
$old = htmlentities($old, ENT_QUOTES, "UTF-8");
$new = htmlentities($new, ENT_QUOTES, "UTF-8");
$out = <<<EOF
<audit_detail>
<fieldname>{$field}</fieldname>
<old_value>{$old}</old_value>
<new_value>{$new}</new_value>
</audit_detail>
EOF;
return $out;
}
The insert in the database is done like this:
function ed_audit_insert($ed, $xml){
global $visitor;
$sql = <<<EOF
INSERT INTO ed.audit
(employee_id, audit_date, audit_action, audit_data, user_id)
VALUES (
{$ed[emp][employee_id]},
now(),
'{$ed[audit_action]}',
'{$xml}',
{$visitor[user_id]}
);
EOF;
$req = mysql_query($sql,$ed['db']) or die(db_query_error($sql,mysql_error(),__FUNCTION__));
}
The weirdest part is that the following works (without the xml declaration though) in a simple PHP file:
$testxml = <<<EOF
<audit><audit_detail>
<fieldname>role_fra</fieldname>
<old_value>Role en français</old_value>
<new_value>Role ç en français</new_value>
</audit_detail></audit>
EOF;
$xmlData = simplexml_load_string($testxml);
Can someone help shed some light on this?
Edit #1 - I'm now using DOM to build the XML document and have gotten rid of the error. Function here:
$dom = new DomDocument();
$root = $dom->appendChild($dom->createElement('audit'));
$xmlCount = 0;
if($role_fra != $curr['role']['role_fra']){
$root->appendChild(ed_audit_node($dom, 'role_fra', $role_fra, $curr['role']['role_fra']));
$xmlCount++;
}
...
function ed_audit_node($dom, $field, $new, $old){
//create audit_detail node
$ad = $dom->createElement('audit_detail');
$fn = $dom->createElement('fieldname');
$fn->appendChild($dom->createTextNode($field));
$ad->appendChild($fn);
$ov = $dom->createElement('old_value');
$ov->appendChild($dom->createTextNode($old));
$ad->appendChild($ov);
$nv = $dom->createElement('new_value');
$nv->appendChild($dom->createTextNode($new));
$ad->appendChild($nv);
//append to document
return $ad;
}
if($xmlCount != 0){
ed_audit_insert($ed,$dom->saveXML());
}
However, I think I now have a display problem as this text "Roééleç sé en franêais" (new_value) is being displayed as:
display problem:
In my HTML document, I have the following declaration for content-type (unfortunately, I don't hold the keys to make changes here):
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
...
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
I've tried iconv() to convert to ISO-8859-1, however, most of the special characters are being removed when doing the conversion. All that remains is "Ro" using this command:
iconv('UTF-8','ISO-8859-1',$node->new_value);
iconv output:
The field in the db is: utf8_general_ci. However, the connection charset would be whatever is the default.
Not quite sure where to go from here...
Edit #2 - I tried utf8_decode to see if that wouldn't help, but it didn't.
utf8_decode($a->new_value);
Output:
I also noticed that my field in the db did contain UTF-8. Which is good.
When
çis "ç", then your encoding is Windows-1252 (or maybe ISO-8859-1), but not UTF-8.
