You can use this.

 $content = 'any text';
 $file = fopen('file.txt','a');
 fwrite($file,$content);

Have you noticed i used mode a

"a" (Write only. Opens and writes to the end of the file or creates a new file if it doesn't exist)

Note: This will only work when you have appropriate permission for test.txt else it will say

permission denied (un-appropriate will lead to this)

Here we are using:

1. a which is for append this will append text at the end of file.

2. instead of w, flag w is for write, which will write on file without caring about you existing data in that file.

PHP code:

<?php
ini_set('display_errors', 1);
$txt = 'srge';
$file = fopen('text.txt','a');
fwrite($file,$txt);

Try with following code

$txt = 'srge';
$file = fopen('text.txt','a');
fwrite($file,$txt);

Writing or Appending to a File

The processes for writing to or appending to a file are the same. The difference lies in the fopen() call. When you write to a file, you should use the mode argument "w" when you call fopen():

$fp = fopen( "test.txt", "w" );

All subsequent writing will occur from the start of the file. If the file doesn't already exist, it will be created. If the file already exists, any prior content will be destroyed and replaced by the data you write.

When you append to a file, you should use mode "a" in your fopen() call:

$fp = fopen( "test.txt", "a" );

according to php documentation:

while you are using :

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

try instead:

'a' Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it. In this mode, fseek() has no effect, writes are always appended.
