I have a php script that writes a string to a file. It sometimes works when loading the URL in my browser and sometimes it doesn't. How do I know? I echoed the string to the browser - which shows the correct string AND the returned value of fwrite, or the number of bytes written, but when I check the file either by opening the file in my browser or via ftp, the file is not consistently updated - sometimes it is, but not always.
I created a simpler version of my fwrite script - creating a string, and writing it to a file, and it works by loading the URL in the browser - updating my file - every single time. The only difference is that I echo the fwrite as below.
Works 100% example
$test = time();
$file = fopen("test.txt","w");
$contents = time()." - Hello World. Testing! - ".time();
echo "contents: ".$contents."
$outstr = '';
$outstr = $outstr.'.... some long string about 2000 characters long.....';
$nxtStr = '';
$outstr = $outstr.$nxtStr;
$file = fopen("markers-nxt.xml","w");
$size = fwrite($file,$outstr);
echo "wrote: ".$size;
Obviously, the files are local. error_reporting(E_ALL) throws no errors. Can someone tell me what's going on? Is there a flushing problem? if so, what is the best way to flush?
