please make If structure

[hanpedro]

I am making thumbnail viewer with serveral sources, however I can not make one file.

<? for ($i=0; $i<count($list); $i++) { ?
$m++;
	//1. get from uploaded thumbnail

	$data_path = $g4[path].'/data/file/$bo_table';
	$thumb_path = $data_path.'/thumb';
	$image = $list[$i][file][0][file]; 
	$img=$data_path. "/".$image;  
	$thumb = $thumb_path. "/". $list[$i][wr_id];	
  if  ( file_exists($thumb) )  {
			return $img_path = $thumb;		
		}


//2. get from linked 

	$data =  $list[$i]['wr_content'] ; 

if ($list[$i][file][1][file]) { 
         $file = $list[$i][file][1][path] .'/'. $list[$i][file][1][file];
	}else if ($list[$i][file][0][file]) {
         $file = $list[$i][file][0][path] .'/'. $list[$i][file][0][file];
	}
	if (preg_match("/\.(jp[e]?g|gif|png|btm)$/i", $file) && file_exists($file)) {
		$img_path = $file ;

	//3. get from body's link
	}else{		

		preg_match('/img.*?src=(.*?) /i', $data, $aaa); 		
		$img_path = $aaa[1];		 

		$del_str_arr = array('"', "'");
		$img_path = str_replace($del_str_arr, "", $img_path);
		$img_path = trim($img_path); 
print_r($i."-5::=> ".$img_path."</br>");				
		}

	$subj_len = $z2[width] ? $z2[width] : 35 ;  
	$data_len = $z2[data_width] ? $z2[data_width] : 300 ;   

	$del_str_arr = array("===", "---");
	$data = str_replace($del_str_arr, "", $data);		

	$subj = cut_str(trim(strip_tags($list[$i]['subject'])),$subj_len,'..');  
	$data = cut_str(trim(strip_tags($data)),$data_len,'...'); 
?>

Please make this "one-If-structure".

I am not sure what you are trying to do.

It is impossible to convert a loop that iterates more than once into a single if statement without the use of goto.

laserlight,

Thanks for your kind reply.

I want a value for "$img_path" at under-mentioned conditions.

1. if "$thumb " exist,
2. if "$file" exist,
3. if "$data[1]" exist.

How can I make this?

why don't you store somewhere which case need to be used at that time when you insert it into database?
