curl - PHP: check if image file exists using fopen -

-

this question using fopen check if file exists, not curl or getimagesize alternative methods not asking about.

i having been using following function in code couple years without problems , returning false, on valid images. don't know if accidentally created typo or if host changed version of php or may have caused appreciate if can spot might going wrong.

here code:

function image_exist($url) {             if (@fclose(@fopen( $url,  "r "))) {              // true; return true;             } else {              // false; return false;             }     }

this returning false on valid images.

why use fopen() , fclose() when there's a function purpose?

function image_exist($url) {     return file_exists($url); }

edit: you're correct not work remote files on http(s).

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
