Hi list,
I have a class which I use to parse simple bbcode inside some comments.
I noticed on PHP5 that scope of preg_replace function is changed
when function is called inside a class. To the point:
[CODE]
class PHS_editor
{
...
function parse_content( $str = null )
{
$from_arr = array( "@\[B\](.*?)\[\/[EMAIL PROTECTED]",
"@\[U\](.*?)\[\/[EMAIL PROTECTED]", "@\[I\](.*?)\[\/[EMAIL PROTECTED]",
"@\[URL=([^\]]*)\]([^\[]*?)\[\/[EMAIL PROTECTED]",
"@\[IMG=([^\]]*)[EMAIL PROTECTED]",
"@\[QUOTE=([^\]]*)\]([^\[]*?)\[\/[EMAIL PROTECTED]"
);
$to_arr = array( '<b>\1</b>', '<u>\1</u>', '<i>\1</i>',
'<a href="\1" target="_blank">\2</a>',
"'<img src=\"'.stripslashes(
\*$this->get_image_location*( '\\1' ) ).'\" border=\"0\">'",
"'<table width=\"98%\" align=\"center\"
cellpadding=\"1\" cellspacing=\"0\" border=\"0\" class=\"form_type\">".
"<tr>".
"<td class=\"maintext\">'.stripslashes(
\*$this->remove_mytags*( '\\2' ) ).'</td>".
"</tr>".
"</table>'"
);
if( is_null( $str ) )
$str = $this->editor_content;
return preg_replace( $from_arr, $to_arr, str_replace( " ", "
", nl2br( $str ) ) );
}
...
}
[/CODE]
When it gets to parse [IMG] tags I get "Fatal error: Using $this
when not in object context in ...". So it seems they changed the scope
for preg_replace callback functions. As this function is called inside
the method shouldn't it have the scope of the class?
Is there a workaround for this? I cannot declare a function
get_image_location which will staticly call the method bcuz I use
variables from instanced class.
Thnx,
Andy
