I want to add all my files that are under "$myfiles" variable in one file called "combined.txt"
I did
echo implode($myfile);
But Im not sure how to make them create and go into a file called "combined.txt"
Use a loop to append the contents of each file to combined.txt.
file_put_contents("combined.txt", ""); // Empty the file first
foreach ($myfiles as $file) {
$contents = file_get_contents($file);
file_put_contents("combined.txt", $contents, FILE_APPEND);
}

I need to find a *.jpg name in a text document. For example I have a folder with pictures file1, file2 , file3 and a text document with file1, file, file3 each on a new line. I need to write near each *.jpg the text from the file, but first I need to find the corresponding row in the text document.
<?php
$arrayF = explode("\n", file_get_contents('myTxt.txt'));
// arrayF should the the array with each text line from the txt file.
while(($file = readdir($opendir)) !== FALSE)
{
if($file!="." && $file!="..")
{
$string=$file;
$arrayS = explode('.', $string);//get the name only without .jpg extension
$search=$arrayS[0];
$key = array_search($search, $arrayF);
echo $key;
}
$string=file_get_contents($file);
file_get_contents
Or if you want it line by line, just open, read and close
$fp = fopen($file, 'r');
while ($line = fread($fp)) {
//do comparision stuff
}
fclose ($fp);
Below is an example to iterate through a directory using DirectoryIterator which provides viewing contents of filesystem directories.
Example:
foreach(new DirectoryIterator($dir) as $file_info)
{
// sleep a micro bit (up to 1/8th second)
usleep(rand(0, 125000));
// disregard hidden, empty, invalid name files
if($file_info == null or $file_info->getPathname() == ''
or $file_info->isDot())
{
continue;
}
// check if its a file - log otherwise
// code omitted
// get filename and filepath
$filepath = $file_info->getPathname();
$filename = $file_info->getFilename();
// my answer to read file linked here to avoid duplication
// below "read/parse file into key value pairs"
}
read/parse file into key value pairs
To elaborate new DirectoryIterator( path to dir ) provides an iterator which can be also written as:
$iterator = new DirectoryIterator($directory);
foreach ($iterator as $fileinfo) {
// do stuffs
}
Hope this helps, indirectly.
i have an application that is used to edit .txt files. the application is made up of 3 parts
Displays contents of a folder with the files to be edited(each file is a link when clicked it opens on edit mode).
writing in to a file.
saving to file.
part 2 and 3 I have completed using fopen and fwrite functions that wasn't too hard. the part that i need help is part one currently I open the file by inputing its location and file name like so in the php file where i have the display function and save function:
$relPath = 'file_to_edit.txt';
$fileHandle = fopen($relPath, 'r') or die("Failed to open file $relPath ! ");
but what i want is for the file to open in edit mode when clicked instead of typing in the files name every time.
$directory = 'folder_name';
if ($handle = opendir($directory. '/')){
echo 'Lookong inside \''.$directory.'\'<br><br>';
while ($file = readdir($handle)) {
if($file !='.' && $file!='..'){
echo '<a href="'.$directory.'/'.$file.'">'.$file.'<a><br>';
}
}
}
this is the code that ti use to display the list of files that are in a specified folder.
Can anyone give me some pointers how I can achieve this ? any help will be greatly appreciated.
To get content of file use file_get_contents();
To put content of file use file_put_contents(); with FILE_APPEND flag for editing.
To recieve list of files in directory you can use DirectoryIterator
Example:
foreach (new DirectoryIterator('PATH/') as $fileInfo) {
if($fileInfo->isDot()) continue;
echo $fileInfo->getFilename() . "<br>\n";
}
If you don't want to put filenames you can put read files once put in db assign ids to them and use links with id param. The other solution is to store files in session array and assign keys for them. When you want to get a file you just need to provide key instead of whole filename and path.
Example with $_SESSION
$file_arr = array();
foreach (new DirectoryIterator('PATH/') as $fileInfo) {
if($fileInfo->isDot()) continue;
$file_arr[] = array("path" => $fileInfo->getPathname(), 'name' => $fileInfo->getFilename());
}
$_SESSION['files'] = $file_arr;
then in view you can use
foreach($_SESSION['files'] as $k=>$file)
{
echo "<a href='edit.php?f=".$k."'>'.$file['name'].'</a>";
}
and edit.php
$file = (int)$_GET['f'];
if(array_key_exits($file, $_SESSION['files'])
{
$fileInfo = $_SESSION[$file'];
//in file info you have now $fileInfo['path'] $fileInfo['name']
}
I have a question and it's probably a simple one. What I would like to do is be able to place a unique name at the top of each .php file in a folder in the php code area. I would then like a script on the index.php file to look in that folder, pull out the unique names of each .php file found at the top of each page in the php code, and display them in a list on the index.php page.
Would I have to do something like this at the top of the page:
< ?
{{{{{uniquenamehere}}}}}
? >
And If so, what would the code look like for grabbing uniquenamehere and displaying in on the index.php page?
Thanks in advance, let me know if I need to be any more clear in my question. Sorry if it's a really simple question, I'm stumped!
EDIT
Getting this warning when using answer below:
Warning: file_get_contents(test.php) [function.file-get-contents]: failed to open stream: No such file or directory in /path/index.php
Here's the code I am using,
<?php
// Scan directory for files
$dir = "path/";
$files = scandir($dir);
// Iterate through the list of files
foreach($files as $file)
{
// Determine info about the file
$parts = pathinfo($file);
// If the file extension == php
if ( $parts['extension'] === "php" )
{
// Read the contents of the file
$contents = file_get_contents($file);
// Find first occurrence of opening template tag
$from = strpos($contents, "{{{{{");
// Find first occurrence of ending template tag
$to = strpos($contents,"}}}}}");
// Pull out the unique name from between the template tags
$uniqueName = substr($contents, $from+5, $to);
// Print out the unique name
echo $uniqueName ."<br/>";
}
}
?>
Not tested, but it should be roughly something like this.
<?php
// Scan directory for files
$fileInfo = pathinfo(__FILE__);
$dir = $fileInfo['dirname'];
$files = scandir($dir);
// Iterate through the list of files
foreach($files as file)
{
// Determine info about the file
$parts = pathinfo($file);
// If the file extension == php
if ( $parts['extension'] == "php" )
{
// Read the contents of the file
$contents = file_get_contents($file);
// Find first occurrenceof opening template tag
$from = strpos($contents, "{{{{{");
// Find first occurrenceof ending template tag
$to = strpos($contents,"}}}}}");
// Pull out the unique name from between the template tags
$uniqueName = substr($contents, $from+5, $to);
// Print out the unique name
echo $uniqueName ."<br/>";
}
}
Thanks in advance.

The error message says that the file isn't found.
This is because scandir() returns only the basename of the files from your directory. It doesn't include the directory name. You could use glob() instead:
$files = glob("$dir/*.php");
This returns the path in the result list, and would also make your extension check redundant.
I would suggest that you need to exclude . and .. from the list of files picked up by scandir() DOCs.
// Iterate through the list of files
foreach($files as $file) {
if('.' == $file or '..' == $file) {
continue;
}
...
Also you need to put the path before your file name:
$contents = file_get_contents($path . $file);
I have, problem.. I display images from dir in ARRAY with button 'delete' - action delete.php..
If I click 'delete' file delete.php should delete image from dir and path from TXT file..
Below PHP code delete only file from dir, I don't know how I can delete PATH from TXT files - I need this script..
TXT file looking that:
../../gallery/glowna//thumb_1300625269.jpg|
../../gallery/glowna//thumb_1300625300.jpg|
../../gallery/glowna/thumb_1300626725.jpg
And delete.php
<?php
$plik=$_POST['usun'];
$nowa = substr($plik, 6, 20);
unlink('../../gallery/glowna/'.$_POST['usun']);
unlink('../../gallery/glowna/'.$nowa);
header("location:usun.php");
?>
I trying use below code, but something is wrong, because TXT file are cleaning ALL:
$txt = "../../dynamic_ajax.txt";
$img = "../../gallery/glowna/".$_POST['usun'];
$file = file_get_contents($txt, true);
$file2 = explode('|', $file);
$search=array_search($img, $file2);
unset($search);
$separator = implode("|", $file2);
file_put_contents($txt, $separator);
Ok think I understand what you mean. This is something I jotted down, you might want to clean up the code a bit.
$q = 'thumb_1300625300.jpg';
$files = file_get_contents('files.txt');
$arr = explode('|', $files);
foreach ($arr as &$file) {
if (strpos($file, $q) !== false) {
$file = '';
break;
}
}
$files = implode('|', $arr);
$files = str_ireplace('||', '|', $files);
file_put_contents('files.txt', $files);
Pretty simple code.
Opens up the file and splits it by |
Then it loops through the arrray looking for the path that matches the image and makes it empty and then skips the loop
Then you implode the string and then remove the double | because we removed an element
A couple of caveats. This script only looks for one instance of the path. If you have multiple, then let the loop run its course and remove the break. You also need to modify str_ireplace('||', '|', $files); so that it will look for multiple |
What about this?
$file = file_get_contents($txt, true);
$file2 = explode('|', $file);
$new_array = Array();
foreach ($file2 as $path) {
if (/* path should be preserved */) {
$new_array[] = $path;
}
}
$new_contents = implode("|", $new_array);
file_put_contents($txt, $new_contents);
But be aware that a little while after you put this on a public server, your TXT file will be gone. Imagine this:
1st process (thread) opens the file for writing (truncating it to 0 characters).
2nd process reads the empty file.
1st p. writes good file.
2nd process writes empty file.
You could get around that by using some lock mechanism, but consider other options. If you have only paths in that file, why not having a special folder for your images? Then just list that folder and you know which files are present. If you want to save some metadata with the images, database is your friend.
