![]() It is the real code, it is a little odd situation: // reading png bytes from fileįILE *fp = fopen("./test/resources/RGBA_8bits. I could also before checking with feof() do something like this fread(NULL, 1, 1, fp) I am asking about this because when I add +1 then the number of bytes read by fread() is really -1 byte less, and as the last byte is inserted 00 byte. Should I always add this +1 value to this size to read all bytes from binary file or there is some hidden reason that this isn't reading to EOF? struct stat finfo It returns false! So I need to read (st_size + 1) and only than all bytes have been read and feof() works correctly. I come to this conclusion when I used feof() function to check if there really nothing left in FILE *. If I get the file size's in this way, then allocate a buffer of that size and read exactly that size of bytes there seems to be one byte left over. Now I am considering what the st_size field really means and how should I use it. ![]() So I intend to use fstat() function and struct stat. Note that this function loses the file input names (I usually process the files just by type).I consider reading file of unknown size that I know doesn't change size in the meantime. This function works on many file inputs on the page and also if the inputs are ''. Opens for writing at the end of the file (appending) without removing the end-of-file (EOF) marker before new data is written to the file. If the given file exists, its contents are destroyed. It basically just flattens the $FILES array. If the file doesn't exist or can't be found, the fopens call fails. Here's a function that I have used to get a nice simple array of all incoming files from a page. So you'd need to access the error param of file1 as, eg $_Files ![]() Last I checked (a while ago now admittedly), if you use array parameters in your forms (that is, form names ending in square brackets, like several file fields called "download", "download" etc), then the array format becomes. ![]() => /tmp/php/php1h4j1o (could be anywhere on your system, depending on your config settings, but the user has no control, so this isn't tainted) => text/plain (not sure where it gets this from - assume the browser, so treat as tainted) => MyFile.txt (comes from the browser, so treat as tainted) ![]() 'pos' > i, j, so that it can be used for proper disposition of the file in database array, or for creating automated names that append each index level. The format of this array is (assuming your form has two input type=file fields named "file1", "file2", etc): An additional element 'pos' in the flattened array will hold the 'node path' for each file of a multi-file array, e.g. Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
