fwrite

I have a simple PHP script that writes a file into directory where located, but need to have it written into a directory called "temp". There are many answers here on the subject, but can't seem to find what I need. Have reviewedhttp://us2.php.net/manual/en/function.fwrite.php with no luck. Here is the basic PHP without the form part: <?php function saveFile($filename,$filecontent){ if (strlen($filename)>0){ $file = @fopen($filename,"w"); if ($file != false){ fwrite($file,$filecontent); fclose($file); return 1; } return -2; } return -1; } ?> This appears below the /form tag: <?php if (isset($

When i write to file my results: output=knew[i][0],knew[i][1], knew[i][2],eigenval[k],group[i] value=str(output) o.write(value+'\n') I get: (0.05, 0.05, 0.166667, -0.8513056, 0.9881956035137526) (0.05, 1.05, 0.166667, -0.8513056, 0.011652226336523394) (0.05, -0.9500000000000002, 0.166667, -0.8513056, 0.00015217014972403685) How to write to file so it doesn't add brackets? Instead of value = str(output) you can do value = ', '.join(map(str, output)) What you see is the string representation of a tuple. It's there because you called str on it. What the str.join method does is join an iterable (e

What is the best way to write to a file some text followed by a data frame? The text is created by pasting variables into strings. Example desired output: Here is some text. This line has a variable: Hello World Data frame below the line ================= ID,val1,val2 1,2,3 2,4,6 3,6,9 4,8,12 5,10,15 6,12,18 7,14,21 8,16,24 9,18,27 10,20,30 I can create a string with the initial text: myvar <- "Hello World" out_string <- paste0("Here is some text.\n", "This line has a variable: ", myvar, "\n", "Data frame below the line\n", "=================\n") cat(out_string) And I can write a dataframe to

This is my code, in this code, I am reading an existing array through a function read_from_json, which convert JSON to array , now from remote data I am getting new data so I have to append those data in my existing array without overwriting the whole

I have a structure, that contain string. Something like that: struct Chunk { int a; string b; int c; }; So, i suppose, that i cannot write and read this structure from file using fread and fwrite functions. Because string may reserve different memory capacity. But such code works correctly. Chunk var; fwrite(&var, sizeof(Chunk), 1, file); fread(&var, sizeof(Chunk), 1, file); Is there really some problems in it? You are justified in doubting this. You should only stream POD types with fwrite and fread and string is not POD . You shouldn't do it like this, because different implementations use
