numfmt_format() expects parameter 1 to be NumberFormatter, null given

Question

I recently upgraded my WAMP server and I can't seem to get the Intl extension to work. I've made sure that

• the extension path in both ini files are correct
• the extension is loaded in both inis
• I can see the extension with php --re intl
• I can see an example function with php --rf numfmt_create
• I have icu dlls files in my php folder (icu 46, php 5.3.8, wamp 2.2)
• I have appended C:\wamp\bin\php\php5.3.8 to the PATH in System variables
• The code is correct - working code before wamp upgrade and php manual example codes fail

I'm trying to use the Number Formatter but it gives me some strange errors. Take this example code from the php manual for example:

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
$fmt = numfmt_create( 'it', NumberFormatter::SPELLOUT );
echo numfmt_format($fmt, 1142)."\n";
?>

It gives me this:

A PHP Error was encountered

Severity: Warning

Message: numfmt_format() expects parameter 1 to be NumberFormatter, null given

Filename: controllers/test.php

Line Number: 867

Backtrace:

I notice that numfmt_create() seems to be returning NULL regardless of what I do.

Answer 1

Apparently the 64 version of WAMP did not have correct icu dlls - using the 32 version worked.

Answer 2

can you run the icuinfo.exe tool from ICU to see if ICU is loading its data properly?
