note 116781 added to book.simplexml

XML data values should not contain "&" and that need to be replaced by html-entity "&amp;" You can use this code to replace lonely "&" to "&amp;": <?php $sText = preg_replace('#&(?![a-z]{1,6};)#i', '&amp;', $sText); ?> This will replace just "&" into "&amp;" but dont touches other html-entities like "&nbsp;", "&lt;" etc and, of course, "&amp;". P.S. In regexp max length is 6 becouse I found that is the maximum length of possible html entity using this code: <?php max(array_map('strlen', array_values(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES | ENT_HTML5)))) - 2 ?> minus two is for first "&" and last ";" in an any html entity. ---- Server IP: 72.52.91.14 Probable Submitter: 176.36.73.22 ---- Manual Page -- http://php.net/manual/en/book.simplexml.php Edit -- https://master.php.net/note/edit/116781 Del: integrated -- https://master.php.net/note/delete/116781/integrated Del: useless -- https://master.php.net/note/delete/116781/useless Del: bad code -- https://master.php.net/note/delete/116781/bad+code Del: spam -- https://master.php.net/note/delete/116781/spam Del: non-english -- https://master.php.net/note/delete/116781/non-english Del: in docs -- https://master.php.net/note/delete/116781/in+docs Del: other reasons-- https://master.php.net/note/delete/116781 Reject -- https://master.php.net/note/reject/116781 Search -- https://master.php.net/manage/user-notes.php
