#40155 [Fbk->Opn]: Error in sample code in documentation for html_entity_decode

ID: 40155 User updated by: onerob at gmail dot com Reported By: onerob at gmail dot com -Status: Feedback +Status: Open Bug Type: Documentation problem Operating System: any PHP Version: Irrelevant New Comment: Correction and clarification: The PHP4 function example gets confused if you use a decimal HTML entity with a leading zero, e.g. &#039; instead of &#39; For example, the following code should really output a single quote character but actually outputs nothing - <?php // For users prior to PHP 4.3.0 you may do this: function unhtmlentities($string) { // replace numeric entities $string = preg_replace('~&#x([0-9a-f]+);~ei', 'chr(hexdec ("\\1"))', $string); $string = preg_replace('~&#([0-9]+);~e', 'chr(\\1)', $string); // replace literal entities $trans_tbl = get_html_translation_table(HTML_ENTITIES); $trans_tbl = array_flip($trans_tbl); return strtr($string, $trans_tbl); } echo unhtmlentities('&#039;'); ?> To correct this, changing the following line from $string = preg_replace('~&#([0-9]+);~e', 'chr(\\1)', $string); to $string = preg_replace('~&#([0-9]+);~e', 'chr("\\1")', $string); is adequate (double quotes added around \\1). A similar fix could no doubt be provided for the preceding line in the function, also.
