I am trying to overwrite files i created in php
when i'm using file_put_contents i receive 0 of "x" bytes written
with the function below that uses fwrite i get the error the file is not writable.
the permissions are 777 (including the directories)
there is no problem creating files, the problem is when i try to modify them.
can anyone figure what is the problem?
function update_body($body)
{
$URL = $_REQUEST["URL"];
$filename = $URL;
$somecontent = $body;
if (is_writable($filename))
{
if (!$handle = fopen($filename, 'w'))
{
echo "Cannot open file ($filename)";
exit;
}
if (fwrite($handle, $somecontent) === FALSE)
{
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
}
else
{
echo "The file $filename is not writable";
}
}
the procedure where i create the file
function save_body($body)
{
$datearr = getdate(); //get date array, use date for folder, time for filename
$current_date = $datearr['year'].$datearr['mon'].$datearr['mday'];
$current_time = $datearr['hours'].$datearr['minutes'].$datearr['seconds'];
// create directory according the date
if (!file_exists($_SERVER['DOCUMENT_ROOT'] .'/articles/'.$current_date))
mkdir($_SERVER['DOCUMENT_ROOT'] .'/articles/'.$current_date, 0777, true);
// write the file
$fp = fopen($_SERVER['DOCUMENT_ROOT'].'/articles/'.$current_date.'/'.$current_time.'.txt',"w");
fwrite($fp,$body);
fclose($fp);
return $current_date.'/'.$current_time;
}
Welcome to Stack Overflow.
As #Sebas said, try to use a relative path (../../../articles) or wherever your folder is instead of
$_SERVER['DOCUMENT_ROOT']
Have a nice day!

if (is_writable($filename2)) {
if (!$handle = fopen($filename2, 'a')) {
echo "Cannot open file ($filename2)";
exit;
}
if (fwrite($handle, $datass) === FALSE) {
echo "Cannot write to file ($filename2)";
exit;
}
fclose($handle);
} else {
echo "The file $filename2 is not writable";
}
}
$filename2 = 'test.txt';
and this code work and the info come on test.txt but I want to process more files like test.txt and test2.txt.
How can I do this?
Not sure what you want to achieve, but maybe you want to extract a function and then use that function to write to multiple files?
function writeToFile($filename, $content)
{
if (!is_writable($filename2)) {
echo sprintf(
'The file "%s" is not writable',
$filename
);
return;
}
$handle = fopen($filename, 'a');
if (false === $handle) {
echo sprintf(
'The file "%s" cannot be opened',
$filename
);
return;
}
$written = fwrite($handle, $data);
fclose($handle);
if (false === $written) {
echo sprintf(
'Could not write to file "%s"',
$filename
);
}
}
$data = '...';
writeToFile('test.txt', $data);
writeToFile('test2.txt', $data);
Note Opening files with fopen() and mode a and then writing using fwrite() will append to existing files, otherwise create new files. Also, you should still close the file handle with fclose(), even if you were unable to write to the file.
For reference, see:
http://php.net/manual/en/language.functions.php
http://php.net/manual/en/function.fopen.php
http://php.net/manual/en/function.fwrite.php
http://php.net/manual/en/function.fclose.php
I try this:
<?php
$time = time();
$fh = fopen("cron.txt", 'a+');
fwrite($fh, $time);
echo "ok";
?>
to run on SSH:
/opt/bitnami/php/bin/php /opt/bitnami/apache2/htdocs/cron.php
and remote server:
budzinski.xyz/cron.php
on localhost it works fine, on remote server and on cron, don't
your cron command needs to modified like this-:
/opt/bitnami/php/bin/php /home/[yourcpanelname]/[your patht to the file]/cron.php
check the permissions of file is it writable or not
Try out this example and than see if you are getting any output or not
<?php
$filename = 'test.txt';
$somecontent = "Add this to the file\n";
// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {
// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}
// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
} else {
echo "The file $filename is not writable";
}
?>
I want to create a php script that will check if a certain html file exist or not. if it doesn't exist, then create a new one and give it a name.
I have tried the code below, but still not working.
$file = file_get_contents(site_url('appraisal/createReport'));
$filename = 'Service_delivery_report_'.date('Y-m-d', time()).'.html';
$filepath = dirname(__DIR__).'/views/sd_reports/'.$filename;
write_file($filepath, $file);
if(! file_exists ($filename))
{
$fp = fopen($filename, 'w');
fwrite($fp, $file);
fclose($fp);
}
I'm not familiar with the method you're using called 'site_url'. From a quick google search it looks like it's a method in Word Press. Ignoring the site_url method, you might want to test using a specific url, like http://ted.com for example. I've specified is_file rather than file_exists because file_exists will return true even if the path you've specified is a directory, whereas is_file will only return true if the path is an actual file. Try this code, setting the $site variable to a site url or path to a file.
I've also switched some code around, doing a check first to see if the file exists before attempting to read in the contents of $site. This way, if the file already exists, you're not needlessly reading in the contents of $site.
$filename = "Service_delivery_report_" . date("Y-m-d",
time()). ".html";
$filepath = realpath("./") . "/views/sd_reports/" . $filename;
if (!is_file($filepath))
{
$site = "http://somesite.com/somepage";
if ($content = file_get_contents($site))
{
file_put_contents($filepath,
$content);
}
else
{
echo "Could not grab the contents of some site";
}
}
Use file_exists();
<?php
$filename = '/path/to/foo.txt';
if (file_exists($filename)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
?>
Then, if it doesn't exist, create a file with fopen();, like so:
$handle = fopen($filename, "w");
Try this
$file = file_get_contents(site_url('appraisal/createReport'));
$filename = 'Service_delivery_report_'.date('Y-m-d', time()).'.html';
if(! file_exists ($filename))
{
$f = fopen($filename, "w");
fwrite($f, $file);
fclose($f);
}
else
echo "file already exist";
I need to read only pdf files in a directory and then read the filename of every files then I will use the filename to rename some txt files. I have tried using only eregi function. but it seems cannot read all I need. how to read them well?
here's my code :
$savePath ='D:/dir/';
$dir = opendir($savePath);
$filename = array();
while ($filename = readdir($dir)) {
if (eregi("\.pdf",$filename)){
$read = strtok ($filename,"."); //get the filenames
//to rename some txt files using the filenames that I get before
//$testfile is text files that I've read before
$testfile = "$read.txt";
$file = fopen($testfile,"r") or die ('cannot open file');
if (filesize($testfile)==0){}
else{
$text = fread($file,55024);
fclose($file);
echo "</br>"; echo "</br>";
}
}
More elegant:
foreach (glob("D:/dir/*.pdf") as $filename) {
// do something with $filename
}
To get the filename only:
foreach (glob("D:/dir/*.pdf") as $filename) {
$filename = basename($filename);
// do something with $filename
}
You can do this by filter file type.. following is sample code.
<?php
// directory path can be either absolute or relative
$dirPath = '.';
// open the specified directory and check if it's opened successfully
if ($handle = opendir($dirPath)) {
// keep reading the directory entries 'til the end
$i=0;
while (false !== ($file = readdir($handle))) {
$i++;
// just skip the reference to current and parent directory
if (eregi("\.jpg",$file) || eregi("\.gif",$file) || eregi("\.png",$file)){
if (is_dir("$dirPath/$file")) {
// found a directory, do something with it?
echo " [$file]<br>";
} else {
// found an ordinary file
echo $i."- $file<br>";
}
}
}
// ALWAYS remember to close what you opened
closedir($handle);
}
?>
Above is demonstrating for file type related to images you can do the same for .PDF files.
Better explained here
$fp = fopen('log.txt', 'w');
fwrite($fp, 'Missing gallery image for: ' . $row['toolbar_id'] . '\n');
The code above is not writing to the file. the $row['toolbar_id'] is a value from a for each loop. Any suggestions? There is no PHP error, as the file does open as I have debugged that part.
Try this for extra surety
ini_set('display_errors', 'On');
error_reporting(E_ALL);
$fp = fopen('log.txt', 'ab');
if (false === $fp) {
throw new RuntimeException('Unable to open log file for writing');
}
$bytes = fwrite($fp, 'Missing gallery image for: ' . $row['toolbar_id'] . PHP_EOL);
printf('Wrote %d bytes to %s', $bytes, realpath('log.txt'));
fclose($fp);
Edit: Changed the "write" flag (w) to "append" (a) as truncating a log file doesn't sound like a great idea
https://bugs.php.net/bug.php?id=48607
there is a php bug with fwrite and ftp which means the last chunks of files sometimes dont get written when fclose is called directly after fwrite
putting a sleep(1); before fclose fixes the issue, or in your case logging to a file before fclose can also stop it
posting for future reference!
<?php
$filename = 'log.txt';
$somecontent = "Missing gallery image for: ";
if($row['toolbar_id'] != "")
{
$somecontent .= $row['toolbar_id'];
}
if (is_writable($filename)) {
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
} else {
echo "The file $filename is not writable";
}
?>
Try this code... !!
