PHP Warning: mb_ereg_match (): mbregex compile err: premature end char -class
The Unicode Common Locale (CLDR) provides a wealth of information about the relationship between languages and characters. For example, you can determine which characters are used in a particular language by looking at the misc.exemplarCharacters diagram . The source data for these diagrams is stored as XML files, and the sample characters are stored as regular expressions in accordance with the Unicode Regular Expressions UTS18 standard .
Here are some examples of what the UTS18 regex expressions look like:
1. [a à b c ç d e é è f g h i í ï j k l ŀ m n o ó ò p q r s t u ú ü v w x y z]
2. [অ আ ই ঈ উ ঊ ঋ এ ঐ ও ঔ ং \u0981 ঃ ক খ গ ঘ ঙ চ ছ জ ঝ ঞ ট ঠ ড {ড\u09BC}ড় ঢ {ঢ\u09BC}ঢ় ণ ত থ দ ধ ন প ফ ব ভ ম য {য\u09BC} ৰ ল ৱ শ ষ স হ া ি ী \u09C1 \u09C2 \u09C3 ে ৈ ো ৌ \u09CD]
3. [a á b ɓ c d ɗ e é ɛ {ɛ\u0301} f g i í j k l m n {ny} ŋ o ó ɔ {ɔ\u0301} p r s t u ú ū w y]
I use PHP and SimpleXML to parse XML data and isolate these regular expression strings. Now I would like to match individual multibyte characters with these regular expressions. I am currently using the mb_ereg_match function , which gives one or more of the following warnings (depending on the regular expression):
mbregex compile err: premature end of char-class in ...
mbregex compile err: empty range in char class in ...
mbregex compile err: empty char-class in ...
Any ideas as to why this is not working?
