Really, when you look at it more closely, this code should not work at all. The following are two alternatives to consider using instead. Improve this answer. Michael Michael You probably want to null-terminate your buffer as well. In your second code sample, you left room for the null, but didn't actually set it; in your first, you neglected to leave room for the null.
This is the way to go. Mark: you're right, and I'm sure you know this, but sizeof int can be 1. Michael, let's say I read a character 'A' in symbol. Alok, Mark: I forgot getc returns an int, not a char.
Wow, that is very subtle. If you open it in text mode, ftell only returns a "cookie" that is only usable by fseek. Show 9 more comments. Yes - you would probably be arrested for your terriable abuse of strcat! Martin Beckett Martin Beckett 92k 25 25 gold badges silver badges bronze badges.

If data is a stream resource, the remaining buffer of that stream will be copied to the specified file. You can also specify the data parameter as a single dimension array.
The value of flags can be any combination of the following flags, joined with the binary OR operator. In other words, a flock call happens between the fopen call and the fwrite call. This is not identical to an fopen call with mode "x". This function returns the number of bytes that were written to the file, or false on failure. This function may return Boolean false , but may also return a non-Boolean value which evaluates to false. Please read the section on Booleans for more information.
Example 1 Simple usage example. A URL can be used as a filename with this function if the fopen wrappers have been enabled.
See fopen for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.

Return Values This function returns the number of bytes that were written to the file, or false on failure.
If anyone has 5. The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Here's a nifty function I use daily. Essentially: include a PHP file - but render its output to a variable, rather than to the buffer.
It's also set up to load the script with a variable set, and automagically loads globals into the script's namespace, making it an effective templating scheme. It also has error handling, so that you're not flying blind when using output buffering. I am at a loss to why no error message appears and am trying to get a working example for the developers that is simpler than my whole program! The only trouble is you will not know where as there is no error!!
If you want to run code in the middle of a string that you made, but you want to wait the printing In case of an error the contents of the output buffer are shown along with the error message. Other functions can be replaced accordingly. Be very careful when returning false from your callback function! In the context of a 'clean' operation e. The answer is to ensure you always return a string value from your callback.
This is likely a bug, and it may get fixed at some point, but it applies to all versions since PHP 5. Note that it was not an issue on PHP 5. I usually create my pages in four parts - variable initialisation, import header using the variables just declared to configure , main body mostly non-PHP , import footer.
I wondered about making the main body examinable by another PHP script if the main page was included into it. I found I could control output of the main body by ending the header with an unclosed function which finishes at the start of the footer, thus enclosing the main body.
Output buffering can then be used to read this into a variable. For the application I mentioned above there are two points to note: - The page when executed alone must output its main body but the inspection script should suppress this, perhaps by means of a variable set before the page is included and then checked for in the footer output lines. These are handy. First one has been mentioned before. A count given to the command above will become the count for the associated motion command.
Thus, 3 d w will delete three words. It is also possible to save the deleted text into a register you specify. For example, you can say " t 3 d w to delete three words and save it to register t. The name of a register is a lower case letter between a and z. If you give an upper case letter as an argument to a delete command, then the deleted text will be appended to the content of the register having the corresponding lower case letter as its name.
So, " T d w will delete a word and append it to register t. Other modifying commands also accept a register name as their argument, and we will not repeat similar explanations. Yank commands yank a text of buffer into a usually anonymous register. Thus yank commands do not alter the content of the buffer, and useful only in combination with commands that put back the yanked text into the buffer.
Thus, " c p will put back the content of the register c into the buffer. It is also possible to specify number register which is a numeral between 1 and 9. VIP records the previous modifying command, so that it is easy to repeat it. It is also very easy to undo changes made by modifying commands. The following keys are reserved for future extensions, and currently assigned to a function that just beeps vip-nil. VIP uses a special local keymap to interpret key strokes you enter in vi mode.
The following keys are bound to nil in the keymap.
