Php call to undefined function iconv in

Не работает функция iconv(), а нужно конвертнуть из UTF-8 в windows-1251

Реально очень полезная выручалка, в том случае если никак не получается совладать с кодировкой и локалями на серваке.

а куда ее вставить? я в пхп не силен, у меня на каталоге VirtueMart такая хрень. причем первый раз. раньше как то не было. хз в чем проблема

Не всегда функция strlen() на хостингах включена, встречалась и такая проблема, поэтому еще один вариант, более актуальный:

function utf8_to_win1251($text)

Summary
When attempting to search and replace in the database, issue the following command and receive the following response:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'ReactiveChild\ReactiveChildFunctions' does not have a method 'meta_boxes' in /home/monroeathazeltin/public_html/wp-includes/class-wp-hook.php on line 286 Fatal error: Call to undefined function Symfony\Polyfill\Mbstring\iconv() in phar:///home/monroeathazeltin/wp-cli.phar/vendor/symfony/polyfill-mbstring/Mbstring.php on line 534 

$ php --ri iconv iconv iconv support => enabled iconv implementation => glibc iconv library version => 2.12 Directive => Local Value => Master Value iconv.input_encoding => no value => no value iconv.output_encoding => no value => no value iconv.internal_encoding => no value => no value 

The text was updated successfully, but these errors were encountered:

Weird though in this case if iconv() is enabled, hard to make sense of it.

Right. Iconv is enabled per the data I provided. Both links shared here presuppose that it isn’t installed?

@holisticnetworking would it be possible for you to install the PHP extension xdebug so that a stack backtrace is generated on the error in order to debug further what’s happening here?

@gitlost I’ve got xdebug installed. But can you give me a little insight as to what you want to see?

Sorry, but I’ve only ever used xdebug with PHPStorm locally, and even that, not terribly successfully.

Just wanted to see what was calling mb_strwidth() to cause the error you’re getting at Mbstring.php#L534. With xdebug installed, should get a Stack trace which will show what’s calling it. Only need to run WP-CLI with it enabled on the command line.

(May not give much more info, to be honest, but may build a PHP with iconv disabled if have further clues. )

@holisticnetworking if you could post the output of wp cli info it’d be useful as well ta.

Hmm, just noticed you said you’ve got xdebug already installed! Could you do php —info | grep xdebug to be sure?!

Okay reproduced the error message with a PHP with iconv() disabled (and xdebug installed):

Fatal error: Uncaught Error: Call to undefined function Symfony\Polyfill\Mbstring\iconv() in phar:///home/mburke/bin/wp/vendor/symfony/polyfill-mbstring/Mbstring.php:534 Stack trace: #0 phar:///home/mburke/bin/wp/vendor/symfony/polyfill-mbstring/bootstrap.php(46): Symfony\Polyfill\Mbstring\Mbstring::mb_strwidth('Table', 'ASCII') #1 phar:///home/mburke/bin/wp/vendor/wp-cli/php-cli-tools/lib/cli/cli.php(345): mb_strwidth('Table', 'ASCII') #2 phar:///home/mburke/bin/wp/vendor/wp-cli/php-cli-tools/lib/cli/Colors.php(200): cli\strwidth('Table', 'ASCII') #3 phar:///home/mburke/bin/wp/vendor/wp-cli/php-cli-tools/lib/cli/table/Ascii.php(138): cli\Colors::width('Table', false, 'ASCII') #4 phar:///home/mburke/bin/wp/vendor/wp-cli/php-cli-tools/lib/cli/Table.php(146): cli\table\Ascii->row(Array) #5 phar:///home/mburke/bin/wp/vendor/wp-cli/php-cli-tools/lib/cli/Table.php(125): cli\Table->getDisplayLines() #6 phar:///home/mburke/bin/wp/vendor/wp-cli/search-replace-command/src/Search_Replace_Command.php(376): cli\Table->display() #7 [i in phar:///home/mburke/bin/wp/vendor/symfony/polyfill-mbstring/Mbstring.php on line 534 

so I think the PHP you’re using must have iconv() disabled, despite the results of php —ri iconv posted.

not including the iconv polyfill is deliberate Symfony policy, maybe adding a check to WP-CLI to warn if both iconv and the mbstring aren’t available is something to be considered, to avoid this user experience.

(May also gird myself up to raise an issue/PR about this at Symfony as it’s poor behavior really. )

I’m not sure what the problem is or was: I’ve had mbstring installed forever and certainly installed all the dependencies. However, after installing xdebug and reloading the server, now everything’s fine. Call it gremlins. But I guess I’m ok. Thanks for the help, everybody!
