First let’s go to mistakes.
The first is in the way you are opening the file. According to the documentation from PHP, the way w is only used for file creation.
In your case the correct way is to+. This mode will allow you to open the file for writing and reading.
The second is in the variable name $ess, it does not exist. The correct would be $txt
The third error is in the button "Participating?", how he is inside the form and is set as submit, therefore, it has the function of sending the contents of the textarea to the url /salvar.php
Now, let’s go the solutions.
One of the ways to add new information to the archive is, as I explained earlier, to use the mode to+ with the function fopen.
Another way is to use the function file_put_contents. This function will allow you to create a file or add new information to it.
Fix the button problem "Participating?", you also have two options:
Create a button with the type:button and with the event click, you call a request with the XMLHttpRequest
Create a anchor that can take you to the url /ler_arquivo.php, for example.
How to do
I hope you can read the comments from the files very carefully. My intention is that this code can assist you in understanding the solution.
I hope, too, that you read the links I left at the end to know more in depth and choose the best option for your code.

There are 3 simple ways to capture the contents of a file.
I will post all three, but I will leave two of them I will just quote. I will leave the link so you can read more about them.
I hope you can read the documentation I will leave
to be able to choose better.
<?php
$filename = "arquivo.txt";
/* ************************************* */
/* Forma 1 */
/* ************************************* */
/**
* Arquivo o arquivo no modo somente leitura
*/
$file = fopen($filename, "r");
/* Variável onde ficará o conteúdo do arquivo */
$content = "";
/**
* "Divide" o arquivo em várias partes de 1024 bytes
* e depois percorre todas elas, juntando-as.
*/
while (($line = fread($file, 1024)) != false) {
$content .= $line;
}
/* ************************************* */
/* Forma 2 - Irei deixar comentada */
/* ************************************* */
// Aqui você pode utilizar a função "file_get_contents"
/* ************************************* */
/* Forma 3 - Irei deixar comentada */
/* ************************************* */
// Aqui você poderá utilizar a função "file" e "implode"
/* Imprime o conteúdo na tela */
echo $content;

If possible post as comment next time. It will improve and I will know if there is any other doubt. The error in this code is that a key is missing
}before the?>. By removing the comments you’ve probably removed this character.– Valdeir Psr
