This code what you do is create a file only. The file receitas.txt I can list all the recipes, but if there is not, when I will list the error.

What I want is to click on the list and if there is not the file, create it:

function lerFicheiro(){
    $rec = array();
    $file = './receitas.txt';
    $fh=fopen($file,'r') or die ('Nao foi possivel abrir o ficheiro!');
    $data = fread($fh, filesize($file)) or die ('Nao foi possivel abrir o ficheiro!');;
    fclose($fh);
    $regReceita = explode("\n", $data);
    foreach ($regReceita as $item){
        $registo=explode(";", $item);
        if (count($registo) > 1) {
            $rec[] = array('receita' => $registo[0], 'descricao' => $registo[1]);   
        }
    }
    return $rec;    
}

Use fopen($file,'w') (why do you want to write in the file also correct!?) (if it is read only, use "a"):

function lerFicheiro(){
    $rec = array();
    $file = './receitas.txt';
    $fh=fopen($file,'w') or die ('Nao foi possivel abrir o ficheiro!');
    $data = fread($fh, filesize($file)) or die ('Nao foi possivel abrir o ficheiro!');
    fclose($fh);
    $regReceita = explode("\n", $data);
    foreach ($regReceita as $item){
        $registo=explode(";", $item);
        if (count($registo) > 1) {
            $rec[] = array('receita' => $registo[0], 'descricao' => $registo[1]);   
        }
    }
    return $rec;    
}

Options:

'r' - Opens only for reading; puts the pointer at the beginning of the file.

'r +' - Opens for reading and writing; puts the pointer at the beginning of the file.

'w' - Opens only for recording; puts the pointer at the beginning of the file and erases the content that has already been written. If the file does not exist, try to create it.

'w +' - Opens for reading and writing; puts the pointer at the beginning of the file and erases the content that has already been written. If the file does not exist, try to create it.

'a' - Opens the file for writing only; puts the pointer at the end of the file. If the file does not exist, try to create it.

'a +' - Opens the file for reading and writing; puts the pointer at the end of the file. If the file does not exist, try to create it.

I have tried this here is the error that appears to me -imgur.com/a/7XZvr - Megaluk

Check the file size before fread() :

if(filesize($file) > 0)

-

function lerFicheiro(){
        $rec = array();
        $file = './receitas.txt';
        $fh=fopen($file,'w') or die ('Nao foi possivel abrir o ficheiro!');

       if(filesize($file) > 0) {
           $data = fread($fh, filesize($file)) or die ('Nao foi possivel abrir o ficheiro!');
       } else {
           echo 'Arquivo vazio';
           $data = "";
        }
        fclose($fh);
        $regReceita = explode("\n", $data);
        foreach ($regReceita as $item){
            $registo=explode(";", $item);
            if (count($registo) > 1) {
                $rec[] = array('receita' => $registo[0], 'descricao' => $registo[1]);   
            }
        }
        return $rec;    
    }
