I am trying to make a string that will contain variables.
The resulting string will be a sql query string and must look something
like
" update $table_name set key='$key' , next='$next' where id = $id"
Since the variable name is the same as the key name, I tried to generate
this string with a foreach statement looking something like this:
foreach( $myrow as $key=>$val) {
$sql .= "$key = ' \$$key ' ,";
}
This then makes the string look as follow:
key='$key',next='$next', and I just add the rest of the string to the
front and back, yet, when I now try to use this string in the
mysql_query() function, it does not recognise the '$key' and '$next' as
variables and add them into the db as $key and $next. I need to know how
I am going to make this string "recognise" the variables in them.
