Correction and clarification:
The PHP4 function example gets confused if you use a decimal
HTML entity with a leading zero, e.g. ' instead of
'
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(''');
?>
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.
