Fatal error: [] operator not supported for strings

[Anon]

Out of the blue, am getting this error message on php4/apache/linux:

Fatal error: [] operator not supported for strings

referenced to this line of code (which is inside a function)

the line below worked for 3 months. Now, it chokes.

$error_flag is our global error array, and $zz and $num are just integers

if ($zz==0) $error_flag[] = sprintf("Please enter an amount for selection #%s (%s is invalid)", $num, $zz);

Thanks in advance.

what about giving $error_flag[ ] an index? like $error_flag[4] = sprintf(...); I am not sure what PHP expects to do without.

Huh?

$a_string[]='somevalue' automatically adds somevalue to the array element.

in other places in the code, the above syntax works fine. Here, though, it doesn't.

Had the same problem. I found out, that in one place of my code I used the variable $xyz[] like a string (e. g. $xyz = "anything"). From that point of the script $xyz was nat accepted as array anymore. So take care only to use an array as an array (allways use the "[]" brackets).
