ID: 34056 User updated by: David at Caulkett dot com Reported By: David at Caulkett dot com -Status: Feedback +Status: Open Bug Type: Strings related Operating System: Linux 2.4.22-1.2199.nptlsmp PHP Version: 4.3.11 New Comment:
The problem has to do with passing of arguments from one page to another using POST. Therefore it is difficult to condense a demonstration to ONE file. However, I did provide the simple example code showing the sequence in ONE file. I spent a great deal of time narrowing the problem to a simple test case. The example code was provided in ONE FILE but requires BY THE NATURE OF THE PROBLEM to be executed over several pages in order to demonstrate the problem. It is not possible to provide a snapshot and I can't make it much simpler in ONE FILE as shown under "Reproduce Code."

(one file only!!) ------------------------------------------------------------------------ [2005-10-09 15:17:11] David at Caulkett dot com The problem ocurred on a server handled by http://support.coastinc.com/ PHP version is 4.3.10 . I am unable to provide a snapshot of the server. The test case is simple and hard demonstrable at http://www.reportillegals.com/test1.php. IMHO, either PHP has a bug or the PHP installation is bad. My guess is there is a PHP bug. ------------------------------------------------------------------------ [2005-08-09 20:40:21] David at Caulkett dot com Description: ------------ Actually PHP is version 4.3.10. Passing a string variable from test1 to test2 works fine. Passing the same string from test2 to test3 results in an incorrect length. The length is 30 greater than it should be. PHP seems to be padding the string with 30 spaces which is likely the length of the original INPUT statement. The problem is fixed by removing the extra spaces with the trim function. The test programs are at: http://www.reportillegals.com/test1.php http://www.reportillegals.com/test2.php http://www.reportillegals.com/test3.php The source of the programs are at: http://www.reportillegals.com/test1.txt http://www.reportillegals.com/test2.txt http://www.reportillegals.com/test3.txt Reproduce code: --------------- TEST1 CODE: <html> <body> <form method="POST" name="emailcomments" action="http://www.reportillegals.com/test2.php";> <input type="text" name="User_Email_Address" > <input type="submit" value="PHP Bug Test1 - Enter email address and remember the no. of chars"> </form> </body> </html> TEST2 CODE: <html> <body> <?php $length = strlen ( $User_Email_Address ); echo "length=" . $length; ?> <form method="POST" name="emailcomments" action="http://www.reportillegals.com/test3.php";> <input type="hidden" name="User_Email_Address" value=" <?php print $User_Email_Address;?> "> <input type="submit" value="PHP Bug Test2 - Length should be what you just entered. Just click Submit"> </form> </body> </html> TEST3 CODE: <html> <body> <?php $length = strlen ( $User_Email_Address ); echo "length=" . $length ."<br>"; echo "length is incorrect. it is whatever you entered +30" . "<br>"; $User_Email_Address = trim ($User_Email_Address); $length = strlen ( $User_Email_Address ); echo "length=" . $length ."<br>"; echo "length is now correct after using the trim function.". "<br>"; ?> </body> </html> Expected result: ---------------- The length in test2 and test3 should be the same number of characters as entered in test1. Actual result: -------------- The length is whatever was entered + 30. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=34056&edit=1
