PHP Regex match issue

Question

I'm having trouble matching â character in the string.

For example

if (preg_match("/C[â]mera/i", "Câmera Canon ")) // returns false

but

if (preg_match("/C[a]mera/i", "Camera Canon ")) // returns true

Any idea? why it's working with a but not with â?

Thanks

Have you checked you file encoding?

If you are working with unicode strings (ie. UTF-8), you should use the u flag:

preg_match("/C[â]mera/iu", "Câmera Canon ")

u (PCRE_UTF8)

This modifier turns on additional functionality of PCRE that is incompatible with Perl. Pattern strings are treated as UTF-8. This modifier is available from PHP 4.1.0 or greater on Unix and from PHP 4.2.3 on win32. UTF-8 validity of the pattern is checked since PHP 4.3.5.

Try something like this:

if (preg_match("/C[\pL00E2]mera/u", "Câmera Canon "))

This would match preg_match("/C[\pL00E2]mera/u", "Cemera Canon ") too f.ex.
