Update string from txt file ?

[GShadoW]

Hello @ll

this is my first Q in forum

 

Ok, I have a text file on my android device which I send to server every 2 min's

 

text file contain's only 1 ( single line ) filename gps.txt

that single line in text file look's like this   45:16.2432432;19:2465467;12;4

 

in a server directory I have filename gps.txt ( in that file I store data )

 

curently I use this php on my server ( named upload_file.php )

<?php
  
    $file_path = "uploads/";
     
    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
 ?>

but I only overwrite existing file!!!

what I need is scrip that will add new line without overwriting anything in that file
Can someone help me, I dont know nothing about php.

 

B.R.

You should check out the php manual and the tutorial

 

Here is a simple example can try.

<?php
//read a file
$my_file = "filename.txt";
if (file_exists($my_file)) {
    $data  = file($my_file);
    $total = count($data);
    echo "<br />Total lines: $total<br />";
    foreach ($data as $line) {
        $line = trim($line);
        echo "$line<br />";
    }
    
    //add a new line,note the a
    $write   = fopen($my_file, 'a+');
    //rewind($write);//append to top
    $message = "added a new line here\r\n";
    fputs($write, $message);
    fclose($write);
    
    /*
    //note the w, this will overwrite the entire contents
    $write = fopen($my_file, 'w');
    $message = "I just added this line and overwrote the file\r\n";
    fputs($write, $message);
    fclose($write);
    */
    
} else {
    echo "No file to display";
}
?>

i have placed your code in my php script but it's not working

 

I have only renamed "filename.txt" to my gps.txt

 

can you combine your code with my code in #1 post ?

or

$data = file_get_contents($uploaded_file);
file_put_contents($current_file, $data, FILE_APPEND);

[jcbones]

I'll bite:

 

<?php
 
//expected data: 45:16.2432432;19:2465467;12;4
 
//file_path to the saved file.
$file_path = 'uploads/';
//file name of the temp file:
$file_name =  sys_get_tmp_dir() . $_SERVER['uploaded_file']['tmp_name'];
//name of the saved file.
$new_file = $_SERVER['uploaded_file']['tmp_name'];
 
//if temp file doesn't exist.
if(!file_exists($file_name)) {
 exit('The requested file was not uploaded.');
}
 
//if the file exists, then get it's contents into a string.
$contents = file_get_contents($file_name);
//test for expected data.
$contents = preg_replace('/[^0-9:.;]/','',$contents);
//append it to the saved file, testing to make sure it saved.
if(file_put_contents($file_path . $new_file,$contents . PHP_EOL, FILE_APPEND) !== FALSE) {
 echo 'success.';
}

}

should I rename tmp_name to gps.txt ?

I have try and it not working

 

should I make some changes here ?

 

$file_name =  sys_get_tmp_dir() . $_SERVER['uploaded_file']['tmp_name'];

I send gps.txt from my mobile phone like this

Sub Button1_Click
Label1.Text=""
Label2.Text=""
Dim Path_Phone_Image As String
Path_Phone_Image = File.DirRootExternal & "/"  'OR  "/sdcard/
Dim name_image As String
name_image="gps.txt" 
Up.doFileUpload( ProgressBar1,Label1,Path_Phone_Image & name_image,Url_Php_Page)	
End Sub

my Url_Php_Page is located on my server www.xxxx.xxx/upload_file.php

 

and php look's like this

<?php
  
    $file_path = "uploads/";
     
    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
        echo "success";
    } else{
        echo "fail";
    }
 ?>

it works to save gps.txt but it always overwrite it, not adding new line to existing text inside

[Ch0cu3r]

EDIT. In jcbones code change lines 8, 9 and 10 to

$file_name = $_FILES['uploaded_file']['tmp_name'];
//name of the saved file.
$new_file = $_FILES['uploaded_file']['name']; // or set this variable to 'gps.txt'

You should not need to modify the code provided by jcbones. The code should append the contents of the uploaded file to gps.txt.

 

If the code is not working, then either the file is not being uploaded or it is unable to write to gps.txt. Check your servers error log to see if there are any errors.

Thank you

jcbones & Ch0cu3r

now it works

[GShadoW]

<?php
 
//expected data: 45:16.5555;18:50.83722;1;19:30:35;17052015;1;0
 
//file_path to the saved file.
$file_path = 'uploads/';
//file name of the temp file:
$file_name = $_FILES['uploaded_file']['tmp_name'];
    //name of the saved file.
    $new_file = $_FILES['uploaded_file']['name']; // or set this variable to 'gps.txt'
 
//if temp file doesn't exist.
if(!file_exists($file_name)) {
 exit('The requested file was not uploaded.');
}
 
//if the file exists, then get it's contents into a string.
$contents = file_get_contents($file_name);
//test for expected data.
$contents = preg_replace('/[^0-9:.;]/','',$contents);
//append it to the saved file, testing to make sure it saved.
if(file_put_contents($file_path . $new_file,$contents . PHP_EOL, FILE_APPEND) !== FALSE) {
 echo 'success.';
}

I send to server gps.text and with script above I only update existing gps.text on server with new line ( not overwriting existing file on server )

 

so expected line look like this: 45:16.5555;18:50.83722;1;19:30:35;17052015;1;0

 

I need help, what if I send same text, just last number increasing so it will look like this

 

old 45:16.5555;18:50.83722;1;19:30:35;17052015;1;0

new 45:16.5555;18:50.83722;1;19:30:35;17052015;1;1

 

can I replace that same line with new until last number reaches 5, when reaches 5 then delete whole line

 

example:

 

current line on server is:

45:16.5555;18:50.83722;1;19:30:35;17052015;1;0

 

I send new line which is exactly same except last value ( 1 )

45:16.5555;18:50.83722;1;19:30:35;17052015;1;1 <- update existing line

45:16.5555;18:50.83722;1;19:30:35;17052015;1;2 <- update existing line

45:16.5555;18:50.83722;1;19:30:35;17052015;1;3 <- update existing line

45:16.5555;18:50.83722;1;19:30:35;17052015;1;4 <- update existing line

45:16.5555;18:50.83722;1;19:30:35;17052015;1;5 <- delete line from file

 

update until some line reach last value 5 and then delete it

 

Anyone can help modify above script ?

Weird I cant seem to be able to send you a PM to inform you I have merged your topics seeing as they are similar.

 

Also please do not bump old topics to "advertise" your new topics either.

[GShadoW]
