Recommended Posts

Hi have this function:

function estr($var1, $vfield) { // get de uma expressão
require("conf.php");
$sql = "SELECT * FROM exp where id=$var1";
$result2 = mysql_query($sql, $connection) or die ("Erro no query");
$row2 = mysql_fetch_array($result2);
return $row2[$vfield];
}

and I want put inside a variable

like this


$b = estr(59,$nome);

It seems to me that you are asking 1 of 2 questions:
1:
Can i pass a variable to a function? eg: func($var1, $var2);

The answer is yes.

2:
Will the value of $b in my example be the returnd value of the function?

the answer is yes.


If the function isnt working correctly when passing a variable to it, then the value of the variable is not the name of a collum in your SQL table.
