preg_replace

[ggalan]

i am trying to replace decorative quotes but i keep getting this

it doesnt work here

function ListFiles($dir) {

    if($dh = opendir($dir)) {
		
        $files = Array();
        $inner_files = Array();

        while($file = readdir($dh)) {
				
					$file = trim( preg_replace( "/’/", ''', $file ) );
					$file = utf8_encode($file);
							
            if($file != "." && $file != ".." && $file[0] != '.') {
                if(is_dir($dir . "/" . $file)) {
                    $inner_files = ListFiles($dir . "/" . $file);	
                    if(is_array($inner_files)) $files = array_merge($files, $inner_files); 
                } else {
                    array_push($files, $dir . "/" . $file);//$dir = directory name
                    //array_push($files, $dir);
                }
            }
						
        }// while

				 
				
        closedir($dh);
        return $files;
    }
}

foreach (ListFiles('./') as $key=>$file){
  echo $file ."<br />";
}

but it seems to work here

$folder = "./"; 
$handle = opendir($folder); 


while ($file = readdir($handle)) { 
		$file = trim( preg_replace( "/’/", ''', $file ) );
		$file = utf8_encode($file);
    $files[] = $file; 
} 
closedir($handle); 


foreach ($files as $file) { 
    echo "$file"."<br />"; 
}

any suggestions why it wont work on the first list?

this fixed the single curly quote

$str = preg_replace('/[\x91\x92]/u', """, $str);quotes

//when i spell out the quote in special html char, it converts it to a quote

Try escaping your literals instead.

<?php
$file="this is ’a’ test.";
echo "$file<br>";
$file = trim(preg_replace( "/\’/", '\'', $file));
echo "$file";
?>

Any non alpha numeric value can and probably should be escaped if you want to declare it as a literal value. This is especially true of delimiters. In the above example the forward slash is used as the delimiter and in the second argument of the regular expression the single quote is used as the delimiter.
