Can you reproduce with PHP 7.1 or later? Previous Comments: ------------------------------------------------------------------------ [2019-03-26 00:52:02] christo at iagauctions dot com I am having the same issue with file_exists: I retrieve clients data from the DB, loop through it in while loopd, then check if they have an invoice: $filename = "/invoices/invoice_".$auction_short_name."_".$lname."_".$member_id.".pdf"; if(file_exists($filename)) { $pdf_previw = "<a href=\"/invoices/invoice_".$auction_name."_".$member_name."_".$member_id.".pdf">INVOICE</a>"; } else { $pdf_previw = ""; } This works as expected in all cases EXCEPT when there is an apostrophe in the clients name, IE $member_name=O'Rourke. When i remove the "if(file_exists($filename))" check and just display: $pdf_previw = "<a href=\"/invoices/invoice_".$auction_name."_".$member_name."_".$member_id.".pdf">INVOICE</a>"; it displays it correctly, and when clicked on displays the PDF file as expected. This to me indicates that the file_exists function is not executing properly.

Are you sure the filename doesn't have a backslash?... $ ls file\' 1 file' 2 $ ~/php-t/bin/php <?php var_dump(file_exists("file\' 1"), file_exists("file' 2")); bool(true) bool(true) ------------------------------------------------------------------------ [2011-03-30 14:19:05] f dot roze dot n at hush dot ai Description: ------------ When using built-in function "file_exists" in 5.3.5 I encountered a trouble of locating one file, which had apostrophe in its' name. $filename = "America's Army.png"; if ( file_exists($filename) ) echo "found it"; else echo "bug"; After backslashing the single quote ("America\'s Army.png"), I managed to get things working. I considered this as bug since it has nothing o do with DB/HTML backslashing, and also took me a few hours to find out what the problem was. Test script: --------------- // To test, copy a single file called "America's Army.png" to the initial dir $filename = "America's Army.png"; if ( file_exists($filename) ) echo "found it"; else echo "bug"; Expected result: ---------------- found it Actual result: -------------- bug ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54422&edit=1
