This article describes the example of php implementing obtaining and setting the language class of the user access page, and shares it with everyone for your reference. The specific analysis is as follows:
The User Language Class of this instance gets/sets the language of the page accessed by the user. If the user does not set the access language, Accept-Language is read. Display the corresponding page according to the language selected by the user (English, Simplified Chinese, Traditional Chinese)
UserLang.class.php class file is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 |
