I am taking data from text file( data is: daa1 daa2 daa3 on separate lines) then trying to make folders with exact name but only daa3 folders is created. Also when i use integer it creates all folders, same is the case with static string i.e "faraz".
$file = __DIR__."/dataFile.txt";
$f = fopen($file, "r");
$line =0;
while ( $line < 5 )
{
$a = fgets($f, 100);
$nl = mb_strtolower($line);
$nl = "checkmeck/".$nl;
$nl = $nl."faraz"; // it works for static value i.e for faraz
//$nl = $nl.$a; // i want this to be the name of folder
if (!file_exists($nl)) {
mkdir($nl, 0777, true);
}
$line++;
}
kindly help
use feof function its much better to get file content also line by line
Check this full code
$file = __DIR__."/dataFile.txt";
$linecount = 0;
$handle = fopen($file, "r");
$mainFolder = "checkmeck";
while(!feof($handle))
{
$line = fgets($handle);
$foldername = $mainFolder."/".trim($line);
//$line is line name daa1,daa2,daa3 etc
if (!file_exists($foldername)) {
mkdir($foldername, 0777, true);
}
$linecount++;
unset($line);
}
fclose($handle);
output folders
1countfaraz
2countfaraz
3countfaraz
Not sure why you're having trouble with your code, but I find it to be more straightforward to use file_get_contents() instead of fopen() and fgets():
$file = __DIR__."/dataFile.txt";
$contents = file_get_contents($file);
$lines = explode("\n", $contents);
foreach ($lines as $line) {
$nl = "checkmeck/". $line;
if (!file_exists($nl)) {
echo 'Creating file '. $nl . PHP_EOL;
mkdir($nl, 0777, true);
echo 'File '. $nl .' has been created'. PHP_EOL;
} else {
echo 'File '. $nl .' already exists'. PHP_EOL;
}
}
The echo statements above are for debugging so that you can see what your code is doing. Once it is working correctly, you can remove them.
So you get the entire file contents, split it (explode()) by the newline character (\n), and then loop through the lines in the file. If what you said is true, and the file looks like:
daa1
daa2
daa3
...then it should create the following folders:
checkmeck/daa1
checkmeck/daa2
checkmeck/daa3

How to delete a line from the file with php?
(10 answers)
Closed last year.
i was wondering if it is posible to delete a single line in a txt file with php.
I am storing emailadresses in a flat txt file named databse-email.txt
I use this code for it:
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$email = $_POST['email-subscribe'] . ',' . "\n";
$store = file_put_contents('database-email.txt', $email, FILE_APPEND | LOCK_EX);
if($store === false) {
die('There was an error writing to this file');
}
else {
echo "$email successfully added!";
}
}
?>
Form:
<form action="" method="POST">
<input name="email-subscribe" type="text" />
<input type="submit" name="submit" value="Subscribe">
</form>
The content of the file looks like this:
janny#live.nl,
francis#live.nl,
harry#hotmail.com,
olga#live.nl,
annelore#mail.ru,
igor#gmx.de,
natasha#hotmail.com,
janny.verlinden#gmail.com,
All lines are , seperated
Lets say i want to delete only the emailadres: igor#gmx.de
How can i do that?
What i want to achieve is a unsubscribe form and delete a single line in the .txt file
You can use str_replace
$content = file_get_contents('database-email.txt');
$content = str_replace('igor#gmx.de,', '', $content);
file_put_contents('database-email.txt', $content);
Because of the way the filesystem works you can't do this in an intuitive way. You have to overwrite the file with all the lines except the one you want to delete, here's an example:
$emailToRemove = "igor#gmx.de";
$contents = file('database-email.txt'); //Read all lines
$contents = array_filter($contents, function ($email) use ($emailToRemove) {
return trim($email, " \n\r,") != $emailToRemove;
}); // Filter out the matching email
file_put_contents('database-email.txt', implode("\n", $contents)); // Write back
Here's a streaming alternative solution in the cases where the file does not fit in memory:
$emailToRemove = "igor#gmx.de";
$fh = fopen('database-email.txt', "r"); //Current file
$fout = fopen('database-email.txt.new', "w"); //New temporary file
while (($line = fgets($fh)) !== null) {
if (trim($line," \n\r,") != $emailToRemove) {
fwrite($fout, $line, strlen($line)); //Write to new file if needed
}
}
fclose($fh);
fclose($fout);
unlink('database-email.txt'); //Delete old file
rename('database-email.txt.new', 'database-email.txt'); //New file is old file
There is also a way to do this in-place to minimize extra disk needed but that is trickier.
You can do it programmatically which will just look over every line and if it not what you want to delete, it gets pushed to an array that will get written back to the file . Like below
$DELETE = "igor#gmx.de";
$data = file("database-email.txt");
$out = array();
foreach($data as $line) {
if(trim($line) != $DELETE) {
$out[] = $line;
}
}
$fp = fopen("database-email.txt", "w+");
flock($fp, LOCK_EX);
foreach($out as $line) {
fwrite($fp, $line);
}
flock($fp, LOCK_UN);
fclose($fp);
first read the file using fopen and fget , and make array to list the emails you want to remove , use in_array to check if value exists in array , and then after remove unwanted emails save the file using fwrite and you need to close the file after the read and the write operations using fclose
checkout this code
$data = "";
$emailsToRemove = ["igor#gmx.de" , "janny#live.nl"];
//open to read
$f = fopen('databse-email.txt','r');
while ($line = fgets($f)) {
$emailWithComma = $line . ",";
//check if email marked to remove
if(in_array($emailWithComma , $emailsToRemove))
continue;
$data = $data . $line;
}
fclose($f);
//open to write
$f = fopen('databse-email.txt','w');
fwrite($f, $data);
fclose($fh);
for delete special word and next delete blank line try this:
$file = "file_name.txt";
$search_for = "example_for_remove";
$file_data = file_get_contents($file);
$pattern = "/$search_for/mi";
$file_data_after_remove_word = preg_replace($pattern, '', $file_data);
$file_data_after_remove_blank_line = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $file_data_after_remove_word);
file_put_contents($file,$file_data_after_remove_blank_line);
I need a script that is finding and then replacing a sertain line in a CSV like file.
The file looks like this:
18:110327,98414,127500,114185,121701,89379,89385,89382,92223,89388,89366,89362,89372,89369
21:82297,79292,89359,89382,83486,99100
98:110327,98414,127500,114185,121701
24:82297,79292,89359,89382,83486,99100
Now i need to change the line 21.
This is wat i got so far.
The first 2 to 4 digits folowed by : ar a catergory number. Every number after this(followed by a ,) is a id of a page.
I acces te id's i want (i.e. 82297 and so on) from database.
//test 2
$sQry = "SELECT * FROM artikelen WHERE adviesprijs <>''";
$rQuery = mysql_query ($sQry);
if ( $rQuery === false )
{
echo mysql_error ();
exit ;
}
$aResult = array ();
while ( $r = mysql_fetch_assoc ($rQuery) )
{
$aResult[] = $r['artikelid'];
}
$replace_val_dirty = join(",",$aResult);
$replace_val= "21:".$replace_val_dirty;
// file location
$file='../../data/articles/index.lst';
// read the file index.lst
$file1 = file_get_contents($file);
//strip eerde artikel id van index.lst
$file3='../../data/articles/index_grp21.lst';
$file3_contents = file_get_contents($file3);
$file2 = str_replace($file3_contents, $replace_val, $file1);
if (file_exists($file)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
if (file_exists($file3)) {
echo "The file $filename exists";
} else {
echo "The file $filename does not exist";
}
// replace the data
$file_val = $file2;
// write the file
file_put_contents($file, $file_val);
//write index_grp98.lst
file_put_contents($file3, $replace_val);
mail('info#', 'Aanbieding catergorie geupdate', 'Aanbieding catergorie geupdate');
Can anyone point me in the right direction to do this?
Any help would be appreciated.
You need to open the original file and go through each line. When you find the line to be changed, change that line.
As you can not edit the file while you do that, you write a temporary file while doing this, so you copy over line-by-line and in case the line needs a change, you change that line.
When you're done with the whole file, you copy over the temporary file to the original file.
Example Code:
$path = 'file';
$category = 21;
$articles = [111182297, 79292, 89359, 89382, 83486, 99100];
$prefix = $category . ':';
$prefixLen = strlen($prefix);
$newLine = $prefix . implode(',', $articles);
This part is just setting up the basics: The category, the IDs of the articles and then building the related strings.
Now opening the file to change the line in:
$file = new SplFileObject($path, 'r+');
$file->setFlags(SplFileObject::DROP_NEW_LINE | SplFileObject::SKIP_EMPTY);
$file->flock(LOCK_EX);
The file is locked so that no other process can edit the file while it gets changed. Next to that file, the temporary file is needed, too:
$temp = new SplTempFileObject(4096);
After setting up the two files, let's go over each line in $file and compare if it needs to be replaced:
foreach ($file as $line) {
$isCategoryLine = substr($line, 0, $prefixLen) === $prefix;
if ($isCategoryLine) {
$line = $newLine;
}
$temp->fwrite($line."\n");
}
Now the $temporary file contains already the changed line. Take note that I used UNIX type of EOF (End Of Line) character (\n), depending on your concrete file-type this may vary.
So now, the temporary file needs to be copied over to the original file. Let's rewind the file, truncate it and then write all lines again:
$file->seek(0);
$file->ftruncate(0);
foreach ($temp as $line) {
$file->fwrite($line);
}
And finally you need to lift the lock:
$file->flock(LOCK_UN);
And that's it, in $file, the line has been replaced.
Example at once:
$path = 'file';
$category = 21;
$articles = [111182297, 79292, 89359, 89382, 83486, 99100];
$prefix = $category . ':';
$prefixLen = strlen($prefix);
$newLine = $prefix . implode(',', $articles);
$file = new SplFileObject($path, 'r+');
$file->setFlags(SplFileObject::DROP_NEW_LINE | SplFileObject::SKIP_EMPTY);
$file->flock(LOCK_EX);
$temp = new SplTempFileObject(4096);
foreach ($file as $line) {
$isCategoryLine = substr($line, 0, $prefixLen) === $prefix;
if ($isCategoryLine) {
$line = $newLine;
}
$temp->fwrite($line."\n");
}
$file->seek(0);
$file->ftruncate(0);
foreach ($temp as $line) {
$file->fwrite($line);
}
$file->flock(LOCK_UN);
Should work with PHP 5.2 and above, I use PHP 5.4 array syntax, you can replace [111182297, ...] with array(111182297, ...) in case you're using PHP 5.2 / 5.3.
I have file to edit that contains:
Categories,
Diamond,10,11,
Coal,21,21,
How to add string at the end of line containing "Diamond"?
What I have is code that can add string at the end of a file but don't know how to make it to add that string in specyfic line:
$function_Result = mysql_fetch_row($function_Ask, 0);
$file_To_Edit = "item_Data.csv";
$opened_File = fopen($file_To_Edit, 'w') or die("Error. Code:2 - Can not open file $file_To_Edit");
$string_Data = $function_Result[0] . ",";
fwrite($opened_File, $string_Data);
fclose($opened_File);
I should have used an preg_replace if the file content isn't too large.
$content = file_get_contents('file.txt');
/* in case of unwanted \r */ $content = str_replace("\r", '', $content);
$content = preg_replace("#^(Diamond.*)$#m", '$1' . $append, $content);
file_put_contents('file.txt', $content);
all the previous posted solutions may fail when working on big files. here is one which works on files of any size. (should add some checks if files are readable and writeable etc.)
<?php
$file = "item_Data.csv"
$tmpFile = $file .".tmp";
$in = fopen($file, "r")
$out = fopen($tmpFile, "w")
while (($buffer = fgets($in)) !== false) {
if (preg_match('/my search pattern/', $buffer )) {
$buffer .= 'append this to the matched line';
}
fwrite($out, $buffer);
}
fclose($in);
fclose($out);
unlink($file);
rename($tmpFile, $file);
?>
<?php
$string_Data = '444555';
$file_To_Edit = "./11.csv";
$opened_File = file($file_To_Edit) or die("Error. Code:2 - Can not open file $file_To_Edit"); // Reads entire file into array of file lines
$diamond_lines = preg_grep('#^Diamond#', $opened_File); // Finds array with line started with 'Diamonds'
foreach(array_keys($diamond_lines) as $key) { // Runs 'Diamonds' array
$opened_File[$key] = substr($opened_File[$key], 0, -1) . $string_Data; // Removes the last character from 'Diamond' line (new line chracter) and adds $string_Data variable at the end
}
//var_dump($opened_File);
$f = fopen($file_To_Edit, 'w');
fwrite($f, implode("\n", $opened_File)); // Writes new .CSV file
fclose($f);
?>
Below code splits my file every 10 lines, but I want it to split everytime

function split_file($source, $targetpath='files/', $lines=10){
$i=0;
$j=1;
$date = date("m-d-y");
$buffer='';
$handle = #fopen ($source, "r");
while (!feof ($handle)) {
$buffer .= #fgets($handle, 4096);
$i++;
if ($i >= $lines) {

Any ideas?
If I understand you right, this should do it.
$content = file_get_contents($source);
$parts = explode('</byebye>', $content);
$parts = array_map('trim', $parts);
Then just write the parts to the different files
$dateString = date('m-d-y');
foreach ($parts as $index => $part) {
file_put_contents("{$targetpath}part_{$dateString}{$index}.xml", $part);
}
But I assume (without knowing your source), that this will result in invalid xml. You should use one of the XML-Parser (SimpleXML, DOM, ..) to handle xml-files.
Sidenote: You use # much much too much.
If you are worried about sizes you can switch to a file resource and use fread or fgets to control the amount of memory you are hitting.
$f = fopen($source, "r");
$out = '';
while (!feof($f))
{
$line .= fgets($f);
$arr = explode('</byebye>', $line);
$out .= $arr[0];
if (count($arr) == 1)
continue;
else
{
// file_put_contents here
// will need to handle lines with multiple </byebye> entries here,
// outputting as necessary
// replace $out with the final entry of the $arr array onto
}
}
You can also save more memory by opening up the file for output, and as you parse, pipe the contents to it. When you encounter a entry you would close the file and open the next one.
I assume I'm using the fgets() wrong. I'm tring to open a PHP file and then try to match a line in that file with a variable I create. If the line does match then I want to write/insert PHP code to the file right below that line. Example:
function remove_admin(){
$findThis = '<tbody id="users" class="list:user user-list">';
$handle = #fopen("../../fns-control/users.php", "r"); // Open file form read.
if ($handle) {
while (!feof($handle)) // Loop til end of file.
{
$buffer = fgets($handle, 479); // Read a line.
if ($buffer == '<tbody id="users" class="list:user user-list">') // Check for string.
{
Now I want to write PHP code to the file, starting on line 480. How can I do that?
Useful information may be: IIS 6 and PHP 5.2.
Try this:
<?php
function remove_admin(){
$path = "../../fns-control/users.php";
$findThis = '<tbody id="users" class="list:user user-list">';
$phpCode = '<?php echo \'hello world\'; ?>';
#Import file to string
$f = file_get_contents($path);
#Add in the PHP code
$newfile = str_replace($findThis, $findThis . $phpCode, $f);
#Overwrite the existing file
$x = fopen($path, 'w');
fwrite($x, $newfile);
fclose($x);
}
