　　 How can I use PHP functions that convert traditional Chinese to simplified Chinese?

We define a big5togb function to implement this conversion:

Function big5togb ($ code)
{
// The parameter $ code is a string of the big5 code.
Include 'data _ big5.php'; // file containing big5 data
$ Output = '';
$ Length = strlen ($ code); // Obtain the string length.
$ Code = strtok ($ code ,'');
$ Idx = 0;
While ($ idx <$ length)
{
$ TmpStr = $ code [$ idx]. $ code [$ idx 1];

If (isbig5 ($ tmpStr) // you can determine whether the code is big5.
{
...... // If it is a big5 code, convert it and output it
}
Else
{
$ Output. = $ code [$ idx]; // output directly if it is not a big5 code
}
$ Idx;
}
Return ($ output );
}

How can I use PHP to convert simplified Chinese to traditional Chinese?

We define a big5togb function to implement this conversion:

Function gbtobig5 ($ code)
{
Include 'data _ gb. php'; // data file containing a gb code
$ Output = '';
$ Length = strlen ($ code );
$ Code = strtok ($ code ,'');
$ Idx = 0;
While ($ idx <$ length)
{
$ TmpStr = $ code [$ idx]. $ code [$ idx 1];

If (isgb ($ tmpStr) // Determine whether the code is gb
{
...... // If it is output after gb code conversion
}
Else
{
$ Output. = $ code [$ idx]; // output directly if it is not a gb code
}
$ Idx;
}
Return ($ output );
} In simplified and traditional Chinese conversion, how can I use PHP to output control functions?

What is the PHP output control function?

The PHP output information control function allows you to control the output content of your script, which can be used in many different situations, especially when your script has output information, you need to send the file header and compile and process the output information. The output control function does not affect the header information sent by the application header () or setcookie (). it only applies to data blocks similar to echo (), print (), and PHP code.

Example 1. control output

Test. php
<?
Function test ($ str ){
Return str_replace ('world', 'php', $ str );
}
Ob_start ('test ');
Echo 'hello world ';
Ob_end_flush ();
?>
This program should output
Hello world

However, after the output control function is specified, the output becomes
Hello php

In the above example, the output content of the application echo () will be retained in the output buffer until ob_end_flush () is called or the script stops running, then, the output information is processed by the custom processing function (replacing the strings) and the result is returned.

Coherent function clarification:

Void ob_start ([string output_callback])-open the output buffer

All output information is not directly sent to the browser, but stored in the output buffer. the optional callback function is used to process output information.
