Implementation method of internationalization of PHP program (using gettext)_PHP tutorial

Step 1: Set up the environment
1. First check whether there is the file php_gettext.dll in your php extension directory. If not, you need to
download one or copy it from other places. One, and then put it in the php extension directory.
2. Open php.ini, search for ";extension=php_gettext.dll", then remove the comment and restart apache.
Step 2: Principle explanation
If your non-internationalized program has such code, echo "Hello";, and for internationalized programs, you have to write
echo gettext("Hello");, and then add the English "Hi" corresponding to "Hello" in the configuration file.
At this time, browsing in China will output "Hello" on the screen, while browsing in the United States will output
"Hi" on the screen. In other words, what is finally displayed depends on your configuration file. If the configuration file cannot be found,
will output the content in the program.
Step 3: Encoding test
1. We create a new file hi.php under d:www. The detailed code is as follows

When you run the modified program, only "Hi" will be output. But we are Chinese, we don’t know “Hi”,
we only know “Hello”, then we need to configure the file to take action. Configuration files are generally generated with the help of a tool.
Download address: http://nchc.dl.sourceforge.net/sourceforge/gnuwin32/gettext-0.14.4.exe
After installation, in order to use it in any directory, you need to change the "installation path/bin "Add it to the system environment variables.
Step 4: Generation of configuration file
1. We assume that your tool has been installed and can be used in any directory. Now you need to run cmd and switch the
path to d:www, which is the directory where hi.php is located.
Type xgettext -d hi hi.php --from-code=gb2312, and then execute it. At this time, you can see a newly generated
hi.po file. Note: --from-code=gb2312, where gb2312 can also be utf-8.
2. Open the hi.po file, the display is as follows:

Now there are two The place needs to be modified,
1: "Content-Type: text/plain; charset=CHARSETn"
2: msgstr ""
Change CHARSET in 1 to gb2312, and then change 2 to msgstr "You good".
3. Type msgfmt -o hi.mo hi.po, execute, and the hi.mo file will be generated.
Then create a new localezh_CnLC_MESSAGES directory under d:www and copy hi.mo here.
4. Now restart apache and run it again. "Hello" can be output on the screen.
Others:
If you use utft-8 encoding, you need to use
bind_textdomain_codeset($domain,'UTF-8');
Correspondingly, change CHARSET in hi.po to utf- 8. You also need to save hi.po into utf-8 format,
just generate hi.mo again.
Summary:
We all hope that the programs we write can be used by the public and even internationally, such as the famous wordpress
It is also used internationally. gettext is still very good, simple and easy to use.
