Working with Unicode Advantage PHP Extension |
|
|
The Advantage PHP Extension can read and write Unicode data encoded in UTF-8.
Reading Unicode data is straightforward, with no code changes necessary. (Note that correctly displaying UTF-8 data will require the use of the HTML meta tag to specify that the page uses the UTF-8 character set. For, example, the following HTML head element will properly display UTF-8 data retrieved from Advantage:
<head>
<meta http-equiv=Content-Type content="text/html; charset=utf-8"/>
</head>
Writing Unicode data to Advantage requires the use of parameterized queries. Moreover, parameterized queries must specify the parameter type for Unicode parameters as SQL_WCHAR.
Note that Unicode character literals are not yet supported in PHP.
