php - Using md5_file(); doesn't return the md5 sometimes? -

- 

<?php include_once('booter/login/includes/db.php');  $query="select * shells"; $result=mysql_query($query); while($row=mysql_fetch_array($result, mysql_assoc)){  $hash = @md5_file($row['url']); echo $hash . "<br>";     } ?>

the above code. works flawlessly on urls, every , skip md5 on line, if doesn't retrieve it, though file there.

i can't figure out why. ideas?

edit: when removing '@' returns this:

[function.md5-file]: failed open stream: no such file or directory

the @ in front of md5_file suppresses warnings/errors might raised. removing @ allow errors md5_hash displayed , allow see why failing.

no such file or directory means there no file name has been searched. might want inspect urls causing warnings; maybe refer file has been renamed or moved.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
