Cannot use string offset as an array

[samatair]

I get an error message like this.

Fatal error: Cannot use string offset as an array in D:\www\site\includes\change_preference.inc.php on line 310

[PHP]$cityName["$i"]["$j"] = $row2['city'];[/PHP]
The above code is causing this error. Please let me know what is wrong with this code. How can I rectify this error.

Here $i, $j consists of integer value. which are used to perform a for loop specific number of times. while $row2 brings data from a database.

try $cityName's keys without the quotation marks. if that's not working use var_dump() to check for variable type and content.

Somewhere else you are declaring $cityName as a string and not a variable.

Post the full code using code tags.

I found which caused the error.
I have used a variable name similar to the array name $cityName that caused the confusion.

[PHP]$cityName = 'Dallas';
$cityName["$i"]["$j"] = $row2['city'];
[/PHP]
first I have used the $cityName as a string and then as an array which caused the error. I did not realize this because the above two lines were in different files and was included in another file. I think I should keep more appropriate names depending upon the file and context.
