PHP Import CSV file encountered garbled problem Solution _php Tutorial

Today is mainly to write a PHP import CSV file method, in fact, a lot of online search. Can be implemented how to import. But I encountered two problems when importing, one is to write code on the windows when the test has garbled problem, and then resolved. The second is when it was submitted to the Linux system and it was garbled. I still don't know the reason is garbled, at first I thought it was the code SVN commit error, to the end I asked a question in one of my group, a friend is to do Phpcms, he said he encountered from the Windows submitted to Linux at the beginning of the error always occurred, Later, the reason for troubleshooting is garbled result. The following cut to see how to solve two problems!

Issue One solution:

PHP read the CSV file, in the windows on the Chinese language is not read, I immediately think of a function mb_convert_encoding (); set the following $str = Mb_convert_encoding ($str, "UTF-8", " GBK "); and then it's OK. Of course you can also use Iconv (), set Iconv (' GBK ', "Utf-8//translit//ignore", $str) as follows, and these two functions to solve the problem of garbled characters on Windows.

Problem two settlement:

PHP read CSV file, on Linux appear in the Chinese can not read the situation, Baidu, Google found a solution

is to add a line of code setlocale (Lc_all, ' zh_cn '); Yes, it's blinding your eyes. It's so simple, if you don't know, it might take a lot of time to solve the problem.
PHP setlocale () function explanation
Definition and usage

The setlocale () function sets the region information (geographic information).

Region information is the language, currency, time, and other information for a geographic region. The function returns the current locale setting and returns False if it fails.
The following is a collection of commonly used regional identifiers on the material:

Copy CodeThe code is as follows:
ZH_CN GB2312
en_US. UTF-8 UTF-8
ZH_TW BIG5
ZH_HK Big5-hkscs
Zh_tw. EUC-TW EUC-TW
Zh_tw. UTF-8 UTF-8
Zh_hk. UTF-8 UTF-8
Zh_cn. GBK GBK

For example
Utf-8: setlocale (Lc_all, ' en_US. utf-8′);
Notes: setlocale (lc_all, ' zh_cn ');

The reason to tell everyone setlocale () This function, because I import the CSV file to the Linux system when the garbled, including the use of mb_convert_encoding () and Iconv () two functions are not the final problem. Finally added this sentence setlocale (lc_all, ' zh_cn '); Add the code to the beginning of the import CSV file is easy to fix, and then I looked up the information, found that the fgetcsv () function is sensitive to the locale. Let's say LANG is set to en_US. UTF-8, a single-byte encoded file will have a read error, so we need to set it for culture. Special share to everyone.

I also tried to use the following code is not able to handle, these are generated CSV file header settings. It may not work here, but it might be in your place. So I have to sort out, as far as possible to help meet the import CSV file garbled counterparts, because in the case of no way is really too difficult to deal with. Everyone can try! There is always one that belongs to you.

Copy CodeThe code is as follows:
$csvContent = "Csvzero,csvone,csvtwo,csvthree,csvfour,csvfive";
Header ("Content-type:application/vnd.ms-excel; charset=gb2312 ");
Header ("Pragma:public");
Header ("expires:0");
Header ("Cache-control:must-revalidate, Post-check=0, pre-check=0");
Header ("Content-type:application/force-download");
Header ("Content-type:application/octet-stream");
Header ("Content-type:application/download");
Header ("Content-disposition:attachment;filename=csv data. csv");
Header ("Content-transfer-encoding:binary");
$csvContent = Iconv ("Utf-8", "gb2312", $csvContent);
Echo $csvContent;
Exit
?>

Here's a look at the code for the PHP import CSV file:

Two functions for a brief introduction,

The mb_detect_encoding () character encoding is detected, or false is returned if the encoding of the specified string cannot be detected.

The Fgetcsv () function reads a row from the file pointer and resolves the CSV field. Similar to Fgets (), the difference is that fgetcsv () parses a read-in row and finds a field in CSV format, and then returns an array containing those fields. Fgetcsv () returns FALSE when an error occurs, including when the file ends.

Note: from PHP 4.3.5, the operation of Fgetcsv () is binary safe.

Note: Empty rows in a CSV file are returned as an array containing a single null field and will not be treated as an error.

Note: This function is sensitive to locale settings. Let's say LANG is set to en_US. UTF-8, a single-byte encoded file will receive a read error.

Note: You can activate the Auto_detect_line_endings runtime configuration option if you encounter a line terminator for a Macintosh file that is not recognized by PHP when reading a file.
