fwrite
Name
fwrite — Writes data to a file.
Synopsis
string fwrite(file_handle, data[, bytes]);
resource file_handle: File
handle
string data: Data to be
written
int bytes (optional): Number
of bytes to write
Returns
TRUE on success; FALSE on failure
Description
fwrite() writes the data given in data to the specified file. The optional
bytes argument denotes the
maximum number of bytes to be written to the file (useful
if you don't want to dump all of the data contained in
the data string). If you're using the bytes parameter, the configuration value
of"magic_quotes_runtime"is ignored and no
slashes are stripped from data
. This function is binary-safe, so binary data (such as
an image) can be written as well as text.
Because some of the filesystem functions to read/write
from files partially share the same code, one or more
of the bugs reported elsewhere may also apply to this
function.
3.0.11: Reported to work unreliably on Linux (not
verified).
Example
Example 328. Write data to a
file
$string = "Hello World!\n";
$file = "test.txt";
$fh = fopen($file, "w");
fwrite($fh, $string);
fclose($fh);
echo ("Wrote \"$string\" to file $file");
