Convert an array of numbers into a single string in php

How do I transform an array of numbers into a single string in php?

In the code below the variable $ result is the array of numbers, and I tried to convert it to a single string with the implode () function. But it does not seem to work because php gives the message 'Notice: Array to string conversion in ...' (QUERY LINE

And in the database did not work persistence ...

How to do this conversion? 

//Result é o array de números. Preciso convertê-lo para uma String...
$resultado = implode($result);

        mysqli_query($con,"INSERT INTO forum (codUsuario,titulo,mensagem) VALUES('$result','$titulo','$mensagem');");

In the implode function, I put the empty delimiter and it worked: 

$resultado = implode('', $result);

The problem is that you are including $result in the query and not $resultado , you are doing: 

$resultado = implode($result);

mysqli_query($con,"INSERT forum (...) VALUES('$result','$titulo','$mensagem');");
                                                 ^^^^

Just change to $resultado and it will work normally. The implode , as documented, accepts to invert the parameters. That is both implode($array, '') and implode('', $array) work, as well as only use implode($array) in this case.

Another option - no delimiter needed

Ideone 

$meuArray = array( 1, 2, 3 );
$result="";
foreach( $meuArray  as  $valor ) {
    $result .= $valor;
}
echo $result; // 123

Sandbox 

$meuArray =  [1, 2, 3];
$result="";
foreach( $meuArray  as  $valor ) {
    $result .= $valor;
}
echo $result;
