SOAP-ERROR: Encoding: string … is not a valid utf-8 string

Question

Hi I have a web service built using the Zend Framework. One of the methods is intended to send details about an order. I ran into some encoding issue. One of the values bein

Answer 1

Today I run into same problem - the code which caused that problem was:

$request->Text = substr($text, 0, 40);

changing substr to mb_substr seems to solve the issue:

$request->Test = mb_substr($text, 0, 40, 'utf8');

Answer 2

I fixed a problem like this using mb_convert_encoding with array_walk_recursive to walk into my POST parameters, named $params (array).

Maybe this is useful for you:

array_walk_recursive($params,function (&$item){
    $item = mb_convert_encoding($item, 'UTF-8');
});

Answer 3

What about change the encoding settings:

SERVER:

$server = new SoapServer("some.wsdl", array('encoding'=>'ISO-8859-1')); // for 'windows-1252' too

CLIENT:

$server = new SoapClient("some.wsdl", array('encoding'=>'ISO-8859-1')); // for 'windows-1252' too

... then the conversion is done automatically to UTF-8, I had the similiar problem, so this helped me, so it is tested

Answer 4

The answers above lead me to try:

// encode in UTF-8
$string = utf8_encode($string);

which also resolved the error for me.

Reference: utf8_encode()

Answer 5

I found out that in my case not the encoding of strings was the problem but that the file itself was not saved as UTF-8. Even explicit saving with UTF-8 encoding did not help.

For me it worked to insert a comment with an UTF-8 character like // Å

Answer 6

The problem is that í != i. Try to convert your string to UTF-8 before using in a request. It may look like that:

$string = iconv('windows-1252', 'UTF-8', $string);
