note 114418 added to control-structures.declare

Basically 'declare( encoding = .... );' overrides the zend.script_encoding configuration option (as set in php.ini). However, keep in mind that: * the file encoding must be compatible (at least in the ASCII range of characters) to the zend.script_encoding setting. If you set 'zend.script_encoding' to UTF-8 and save the file in UTF-16, PHP will not be able to interpret the file, let alone the declare statement. As long as you use ASCII compatible encodings (i.e. ISO-8859-1(5), UTF-8 etc) for both the file encoding as the zend.script_encoding, you should be fine. (However, I have not experimented with adding non-ascii characters in comments above the declare statement). * PHP string literals are converted from your source code encoding (either set with the declare statement or else according to zend.script_encoding) to the mbstring.internal_encoding as set in your php.ini (even if you change the setting using mb_internal_encoding). As an example: php.ini: mbstring.internal_encoding = UTF-8 test.php: <?php declare(encoding = 'ISO-8859-15'); mb_internal_encoding( 'ISO-8859-15' ); echo 'aäaß' . "\n"; ?> This will still output the string UTF-8 encoded; in a terminal/browser with encoding 'ISO-8859-15' the string will look (something) like this: aÀaß ---- Server IP: 83.137.20.135 Probable Submitter: 188.207.83.48 ---- Manual Page -- http://php.net/manual/en/control-structures.declare.php Edit -- https://master.php.net/note/edit/114418 Del: integrated -- https://master.php.net/note/delete/114418/integrated Del: useless -- https://master.php.net/note/delete/114418/useless Del: bad code -- https://master.php.net/note/delete/114418/bad+code Del: spam -- https://master.php.net/note/delete/114418/spam Del: non-english -- https://master.php.net/note/delete/114418/non-english Del: in docs -- https://master.php.net/note/delete/114418/in+docs Del: other reasons-- https://master.php.net/note/delete/114418 Reject -- https://master.php.net/note/reject/114418 Search -- https://master.php.net/manage/user-notes.php
