Combining Varriables

If I have two varriable:
$abc
and
$123

If I what to merge then together in a MySQL query in the form:
...WHERE details.id ='$abc_$123'"...

I cant get this to work, or the varriations I can think of.

Please could someone show me how to do it!

Hello!,

You want to do concatenate these strings :

$a = 'foo';
$b = 'bar';

$c = $a . $b; // $c = 'foobar';

$d = $a . '_' . $b; // $d = 'foo_bar';

And also note, variables cannot begin with numbers.

And lastly, please post within one forum at a time (i.e. zend forum is read by people here too)

The manual says that inside double-quoted strings, "variables within the string will be expanded (subject to some parsing limitations)."

Looks as if this is one of those limitations. Since an underscore is legal in a variable name, PHP is replacing $abc_ (whose value is unset).

Workaround would be to use the concatenation operator:

WHERE details.id ='$abc" . '_' . "$def'"

Note that in your example you used $123, which is not a legal variable name.
