Im trying to extract the values between eng_tid
and eng_data for http://fdguirhgeruih.x10.mx/html.txt and I keep getting T string errors.
why do I keep getting errors
<? php
//First, open the file. Change your filename
$file = "http://fdguirhgeruih.x10.mx/html.txt";
$word1='tid';
$word2='data';
$handle = fopen($file, "r");
$contents = fread($handle, filesize($file));
fclose($handle);
$between=substr($contents, strpos($contents, $word1), strpos($contents, $word2) - strpos($contents, $word1));
echo $between;
?>
UPDATE after seeing error messages...
Instead of fread() and attempting to use the size in bytes of your target file, you may simply use file_get_contents() to retrieve the remote file. Your error is because PHP wants to read the filesize of the file as though it is local, but it is a remote file over HTTP. filesize() reports 0 and an error. Instead do
// Don't do this...
//$handle = fopen($file, "r");
//$contents = fread($handle, filesize($file));
//fclose($handle);
// Instead do this...
$contents = file_get_contents($file);

Trying to download files via the URL, rename from the .ADM extension to .txt
then put contents of each file into a single txt file
However its saying the fputs param 2 is a resource
The $logfile['name'] is the filename thats stored in the array
Heres my code
foreach($items as $logfile)
{
$getfile = $logfile['Download'];
$newfile = file_put_contents(str_replace('ADM','txt',$logfile['name']),
file_get_contents($getfile));
$name = str_replace('ADM','txt',$logfile['name']);
$newfile = $name;
$file = fopen($newfile, 'rb');
$output = fopen('tmp/test.txt', 'wb');
fputs($output, $file);
fclose($output);
fclose($file);
}
Its downloading each and renaming however its not moving the content & giving me this error
Warning: fputs() expects parameter 2 to be string, resource given in
The second parameter of fputs is the content of a file. Not a file resource.
Instead of
$file = fopen($newfile, 'rb');
You‘ll need to get the contents of the file
$content = file_get_contents($newfile);
Or, if you like to use fopen, you can use fread:
$file = fopen($newfile, 'rb');
$content = fread($fp, filesize($newfile));
Then you can put this content into another file:
fputs($output, $content);
This code runs very well with fopen:
<?php
$filename = "ftp://$ftp_user_name:$ftp_user_pass#$ftp_server/testes/TJ_IDA.TXT";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
echo $contents;
But when I try with SplFileObject:
$file = new SplFileObject($filename,"r");
I got this error:
Warning: Unknown: FTP server error 426:426 Failure writing network
stream. in Unknown on line 0
Is there another way to use SplFileObject with FTP?
I am trying to write to a file and then read the data from the same file. But sometimes I am facing this issue that the file reading process is getting started even before the file writing gets finished. How can I solve this issue ? How can i make file writing process finish before moving ahead?
// writing to file
$string= <12 kb of specific data which i need>;
$filename.="/ttc/";
$filename.="datasave.html";
if($fp = fopen($filename, 'w'))
{
fwrite($fp, $string);
fclose($fp);
}
// writing to the file
$handle = fopen($filename, "r") ;
$datatnc = fread($handle, filesize($filename));
$datatnc = addslashes($datatnc);
fclose($handle);
The reason it does not work is because when you are done writing a string to the file the file pointer points to the end of the file so later when you try to read the same file with the same file pointer there is nothing more to read. All you have to do is rewind the pointer to the beginning of the file. Here is an example:
<?php
$fileName = 'test_file';
$savePath = "tmp/tests/" . $fileName;
//create file pointer handle
$fp = fopen($savePath, 'r+');
fwrite($fp, "Writing and Reading with same fopen handle!");
//Now rewind file pointer to start reading
rewind($fp);
//this will output "Writing and Reading with same fopen handle!"
echo fread($fp, filesize($savePath));
fclose($fp);
?>
Here is more info on the rewind() method http://php.net/manual/en/function.rewind.php
I have mentioned the URL through which i got the solution. I implemented the same. If you want me to copy the text from that link then here it is :
$file = fopen("test.txt","w+");
// exclusive lock
if (flock($file,LOCK_EX))
{
fwrite($file,"Write something");
// release lock
flock($file,LOCK_UN);
}
else
{
echo "Error locking file!";
}
fclose($file);
Use fclose after writing to close the file pointer and then fopen again to open it.
In PHP im creating a tool to open txt file with an integer in it, increment the number, save the number to a variable and then save and close the file. this is the code i have for it and it doesnt seem to work when i have it on my test server. Can anyone clue me in as to why this isnt working properly?
//opens pclnumber.txt to $handle, saves number to $number, Increments number in text file, saves and closes file
$handle = fopen("pclnumber.txt", "w+");
$number = fread($handle);
fwrite($handle, $number+1);
fclose($handle);
over all you must set reading permission on your file, and than you can use the follow code:
$filename = "pclnumber.txt";
//read file content
$handle = fopen($filename, "r");
$number = fread($handle, sizeof($filename));
fclose($handle);
//update file content
$handleWrite = fopen($filename, "w+");
fwrite($handleWrite, $number+1);
fclose($handleWrite);

I am trying to get the image header from a png file. as the binary content show as neeble how can i show it as hexadecimal? i tried to base_convert() but it is not returning the desired output as i am getting the poutput in hexadecimel editor. any help will be appreciated.I am trying to do it with php
Try this for size:
$filename = "C:\\wamp\\www\\projects\\cog.png";
$handle = fopen($filename, "rb");
$binContents = fread($handle, filesize($filename));
fclose($handle);
$hexContents = bin2hex($binContents);
echo $hexContents;
