What about the error report of iconv function in php?

Introduction to iconv ()

The iconv function converts one known character set file into another known character set file. For example: convert from GB2312 to UTF-8.

The iconv function is built into php5, and the GB character set is turned on by default.

Iconv () error

Iconv will make an error when converting the character "-" to gb2312. The solution is to add "/ / IGNORE" after the encoding to be converted, that is, after the second argument of the iconv function. As follows:

Iconv ("UTF-8", "GB2312//IGNORE", $data)

Ignore means to ignore the conversion error, and without the ignore parameter, all strings following that character cannot be saved.

In php, iconv function library can complete the conversion between various character sets, which is an indispensable basic function library in php programming; but sometimes iconv transcodes part of the data for no reason. For example, there will be an error when converting the character "- or traditional" to gb2312.

Let's take a look at the usage of this function.

For the simplest application, replace gb2312 with utf-8:

`$ text`` = iconv (``"GB2312"``, ``"UTF-8 "``, ``$ text``); `

In the process of using $text=iconv ("UTF-8", "GB2312", $text), if you encounter some special characters, such as "- or traditional", "." in the English name. Wait for the character, the conversion will be broken. The text after these characters can no longer be converted.

To solve this problem, you can use the following code:

`$ text`` = iconv (``"UTF-8"``, ``"GBK "``, ``$ text``); `

You read it correctly. It's as simple as that. Instead of using gb2312, you can write it as GBK.

In another way, the second parameter, plus / / IGNORE, ignores the error, as follows:

`iconv (``"UTF-8"``, ``"GB2312//IGNORE "``, ``$ data``); `

There is no specific comparison between the two methods, so the first method (GBK instead of gb2312) feels better.

Examples are as follows:
