$myFile = "folder1/folder2/order.txt";
$fh = fopen($myFile, 'a');fwrite($fh, $Message);
fclose($fh);
I am use this code.But file is not create in that particular folder
Try this:
<?php
$myFile = "folder1/folder2/order.txt";
$fh = fopen($myFile, 'a'); or die("Unable to open the file");
fwrite($fh, $Message);
fclose($fh);
?>
If this code shows "Unable to open the file" that means there is something wrong while opening the file. This may happen if the folder1/folder2 doesn't exist. Or may be you are not permitted to open a file to write on that folder. If you are in Linux you can change the permission of you directory like this:
chmod 777 folder/folder2
So basically, I have a form that opens a php file when submitted, i have the php writing to a file, but it will not continue adding values, the text file only has one "1" inside of it when it is supposed to have a "1" inside for every time the form has been submitted. Here is my code.
<?php
$myFile = "Data.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "1";
fwrite($fh, $stringData);
fclose($fh);
?>
Any ideas?
Either open in append only format as Robert Rozas stated: fopen($myFile, 'a+');
Or get the contents and do the append manually some pseudo[esk]-code:
$contents = file_get_contents("somefile.txt");
//generate what to write
$contents .= $whatIGenerated;
$success = file_put_contents("somefile.txt", $contents);
Change this one line to this:
$fh = fopen($myFile, 'a') or die("can't open file");
Using w means write, using a means append.
I want to write a line to the end of the file.
My code is:
$myFile = "serialkey.txt";
$fh = fopen($myFile, 'w');
$space = "\r\n";
$stringData = "my new data";
fwrite($fh, $stringData.$space);
fclose($fh);
But when I used this code it deleted all the file and replace "my new data", I want it will not delete my file and append my data to it.
You have it set to write instead of append in
$fh = fopen($myFile, 'w');
It should be
$fh = fopen($myFile, 'a');
Hope this helps.
To insert text without over-writing the end of the file, you'll have to open it for appending (a+ rather than w)
$fh = fopen($myFile, 'a+');
I am a php beginner.I want every time when the web page is open to create a file that does not exist. But every time when I run the program I have an error teling me that the file was not created.
This is my code:
$ip=$_SERVER["REMOTE_ADDR"];
if(!isset($_COOKIE['firsttime'])){
setcookie('firsttime', 'no');
$myfile = 'file/form'.$ip.'.txt';
if(file_exists($myfile) == FALSE){
$fo = fopen($myfile, 'w');
$code = '<form action = "" method = "post">';
fwrite($fo, $code);
fclose($fo);
}else{
unlink($myfile);
$file = new File();
}
}
where is my mistake?
$ourFileName = "testFile.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
Do this to open a file, and it will create the file if it doesn't exist.
Not completely sure but that would result in a pretty weird file name.
$myfile = 'file/form'.$ip.'.txt';
If my ip is 1.0.0.01.23 (really random and pretty weird) the file name would be:
file/form.1.0.0.01.23..txt
Try saving a file with that name in notepad.
I have the following code but I'm trying to shorten it about one or two lines, as I believe the if is unnecessary. Is there any way the code below can shortened to a singular line?
if(file_exists($myFile))
{
$fh = fopen($myFile, 'a');
fwrite($fh, $message."\n");
}
else
{
$fh = fopen($myFile, 'w');
fwrite($fh, $message."\n");
}
if (file_exists($myFile)) {
$fh = fopen($myFile, 'a');
fwrite($fh, $message."\n");
} else {
$fh = fopen($myFile, 'w');
fwrite($fh, $message."\n");
}
fclose($fh);
==
if (file_exists($myFile)) {
$fh = fopen($myFile, 'a');
} else {
$fh = fopen($myFile, 'w');
}
fwrite($fh, $message."\n");
fclose($fh);
==
$fh = fopen($myFile, (file_exists($myFile)) ? 'a' : 'w');
fwrite($fh, $message."\n");
fclose($fh);
== (because a checks if the file exists and creates it if not)
$fh = fopen($myFile, 'a');
fwrite($fh, $message."\n");
fclose($fh);
==
file_put_contents($myFile, $message."\n", FILE_APPEND);
...of course, file_put_contents() is only better if it is the only write you perform on a given handle. If you have any later calls to fwrite() on the same file handle, you're better going with #Pekka's answer.
Umm... why? a already does what you need out of the box.
Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
$method = (file_exists($myFile)) ? 'a' : 'w';
$fh = fopen($myFile,$method);
fwrite($fh, $message."\n");
fopen(). mode a all you need.
$fh = (file_exists($myFile)) ? fopen($myFile,'a') : fopen($myFile,'w');
fwrite($fh, $message."\n");
$fh = file_exists($myFile) ? fopen($myFile, 'a') : fopen($myFile, 'w');
fwrite($fh, $message."\n");
The append mode already does just what you describe. From the PHP manual page for fopen:
'a': Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
According to the php manual this should be enough. See the description of "a"
fopen($myFile, "a");
fwrite($fh, $message."\n");
I believe the a (append) mode does that already... append if exists, else create new
fopen($myFile, "a");
$method = (file_exists($myFile)) ? 'a' : 'w';
$fh = fopen($myFile,$method);
fwrite($fh, $message."\n");
Isn't it $myFile contains absolute/relative path..?
Using the SPL / Standard PHP Library:
# addfile.php
$file = new \SplFileObject( __DIR__.'/foo.txt', 'a' );
var_dump( file_exists( $file->getFilename() ) );
$ php addfile.php
bool(true)
