I'm trying to write data to a simple txt file in PHP and open it so the user can download it. I'd like to keep it very lightweight, when I run this I get:
Warning: fopen(testFile.txt) [function.fopen]: failed to open stream: File exists in /home/user/script.php on line 9
Here is my sample code:
<?php
$File = "sample.txt";
$write = fopen($File, 'w') or die();
$stringData = "asdfjkl;";
fwrite($write, $stringData);
fclose($write);
$open = fopen($File, 'x') or die();
fclose($open);
?>
Thank you!
Use file_put_contents to write to the file:
$filename = "sample.txt";
$stringData = "asdfjkl;";
file_put_contents($filename, $stringData);
Then when you want to output the contents of the file use:
$filename = "sample.txt";
readfile($filename);
If you want the file contents to be returned as a string instead of output immediately use file_get_contents instead of readfile

i am trying to read contents from a text file in php. i am using wamp on windows. i m getting this error:
Warning: fopen(/input.txt): failed to open stream: No such file or directory in C:\wamp\www\cycle_gps_sender.php on line 3
this is my code:
$location = fopen("/input.txt", "r") or die("Unable to open file!");
echo $location;
fclose($location);
both the php file and input.txt are placed in www folder of wamp.
Hope this will help you:
$File = "log_post.txt";
$fh = fopen ($File, 't') or die("can't open file");
fclose($fh);
$location = fopen("input.txt", "r") or die("Unable to open file!");
echo $location;
fclose($location);
Use this code and keep the input.txt file in the same directory where this code is written.
First check if file exist or not?
$filename = '/path/to/foo.txt';
if (file_exists($filename)) {
chmod($filename, 0777);
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
$location = file_get_contents('./input.txt', FILE_USE_INCLUDE_PATH);
echo $location;
or
$location = file_get_contents('input.txt');
echo $location;
hope it will help
Add full path to file.
On the Windows platform, be careful to escape any backslashes used in the path to the file, or use forward slashes.
$location = fopen("C:\\folder\\input.txt", "r");
Remove '/'(Slash)
$location = fopen("input.txt", "r") or die("Unable to open file!");
$file = fopen("path/input.txt","a+") or die("Unable to open file!");
.....
fclose($file);
You have to create file before you READ or if you open file by 'r' , so if you open file by 'a+' , your file will be created automatically.
$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
I want to filter one text file by writing the results to a second text file.
I have a little bit of code and it doesn't work like it should work, it is only writing the LAST line of the first text file into a separate backup text file.
Code:
//filter the ingame bans
$search = "permanently";
$logfile = "ban_list.txt";
$timestamp = time();
// Read from file
$file = fopen($logfile, "r");
while( ($line = fgets($file) )!= false)
{
if(stristr($line,$search))
{
$cache_ig = "ingamebanlist.txt";
$fh = fopen($cache_ig, 'w') or die("can't open file");
$content = "\n";
fwrite($fh, $content);
$content = $line;
fwrite($fh, $content);
fclose($fh);
}
}
I personally do not see any errors in my code, please help.
REMEMBER: It does kind of work, but it only writes the LAST line of the ban_list.txt file into the ingamebanlist.txt file...
What happens with your code is that you open(using write mode), write and close inside your loop so it will only ever write 1 entry then overwrite it until the last entry, thus only saving the last item.
What you want is to have it outside the loop like this:
<?php
$search = "permanently";
$logfile = "ban_list.txt";
$cache_ig = "ingamebanlist.txt";
$timestamp = time();
$read = fopen($logfile, "r") or die("can't read file");
$write = fopen($cache_ig, 'w') or die("can't write to file");
while(($line = fgets($read)) !== false)
{
if(stristr($line,$search))
{
fwrite($write, $line . "\n");
}
}
fclose($write);
fclose($read);
An alternative solution would be to use a instead of w at your fopen since w will:
Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
While a will:
Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
Which would allow your code to work as is without any changes but the line:
$fh = fopen($cache_ig, 'w') or die("can't open file");
To:
$fh = fopen($cache_ig, 'a') or die("can't open file");
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 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.
