Could anybody explain, why this code
$string='6аd_ТЕХТ GOOD_TEXT';
$words = preg_split('/\s+/', $string, NULL, PREG_SPLIT_NO_EMPTY);
var_dump($words);
displays
array(2) { [0]=> string(8) "6àd_ÒÅÕÒ" [1]=> string(9) "GOOD_TEXT" }
instead of
array(2) { [0]=> string(8) "6аd_ТЕХТ" [1]=> string(9) "GOOD_TEXT" }
I've read about this issue, but adding /u :
preg_split('/\s+/', $string, NULL, PREG_SPLIT_NO_EMPTY);// '/\s+/'
to become
preg_split('/\s+/u', $string, NULL, PREG_SPLIT_NO_EMPTY);// '/\s+/u'
doesn't help. How to fix this issue?
Thank you.
There is something else happening in your code that isn't present in the provided example. Tested the provided example and it works as expected. On the off-chance that this is really happening (and there is no other code affecting $string), this may be a bug with the specific PHP version you're using and can be solved by upgrading PHP (but it's highly unlikely that it's an issue with PHP).
... I said it was the slash, but apparently it was the utf-8 stuff that made it work.
EDIT: I removed the rest and found that all I needed was the xml line to make it work in the browser.
<?php
ini_set('default_charset','utf-8');
header('Content-type: text/html; charset=utf-8');
echo '<?xml version="1.0" encoding="UTF-8"?'.'>
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head><body><pre>
';
$string = "6аd_ТЕХТ GOOD_TEXT";
var_dump(preg_split('/\s+/u', $string, NULL, PREG_SPLIT_NO_EMPTY));
echo '</pre></body></html>';
This is the output:
array(2) {
[0]=>
string(13) "6аd_ТЕХТ"
[1]=>
string(9) "GOOD_TEXT"
}
