regex - Matching Unicode letter characters in PCRE/PHP -


i'm trying write reasonably permissive validator names in php, , first attempt consists of following pattern:

// unicode letters, apostrophe, hyphen, space $namepattern = "/^([\\p{l}'\\- ])+$/";

this passed call preg_match(). far can tell, works vanilla ascii alphabet, seems trip on spicier characters Ă or 张.

is there wrong pattern itself? perhaps i'm expecting \p{l} more work think does?

or have way input being passed in? i'm not sure if it's relevant, did make sure specify utf8 encoding on form page.

i think problem simpler that: forgot specify u modifier. unicode character properties only available in utf-8 mode.

your regex should be:

// unicode letters, apostrophe, hyphen, space $namepattern = '/^[-\' \p{l}]+$/u';

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
