PHP5 oop question...

**PHP5 oop question... -** 06-02-2007, 08:55 PM

Hi list,

I have a cl*** 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 cl***. To the point:

Code:

cl*** PHS_editor
{
...

function parse_content( $str = null )
{
$from_arr = array( "@\[B\](.*?)\[\/B\]@sim",
"@\[U\](.*?)\[\/U\]@sim", "@\[I\](.*?)\[\/I\]@sim",
"@\[URL=([^\]]*)\]([^\[]*?)\[\/URL\]@sim",
"@\[IMG=([^\]]*)\]@semi",
"@\[QUOTE=([^\]]*)\]([^\[]*?)\[\/QUOTE\]@semi"
);

$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\" cl***=\"form_type\">".
"<tr>".
"<td cl***=\"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( "  ", "
&nbsp;", nl2br( $str ) ) );
}

...
}

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 cl***?
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 cl***.

Thnx,
Andy

hi all,

does someone ever hear of an internet explorer alert "pcinfinity"?
I really didn´t find anything in forums and search engines, so maybe
somebody in this list knows better...

thanks for answers

How are you trying to use this cl***? It sounds like you're trying to
use the method statically. When a method is called statically it does
not have a $this.

I'm not sure what you mean by "internet explorer alert", but it sounds
like either advertising or you have some malware. Either way this is
definitely not the right place to ask.

Yes, method was called staticly. Strange tho in php 4 it worked.
Thnx for enlighting me with this.
