Array offset

[anuradhu]

Could someone here explain me the reason for this error in detail.....

 

FYI - i am just more than a fresher in PHP.....

 

Fatal error: Cannot use string offset as an array

Can you post the code that gave you that error?

[anuradhu]

Here is the code

 

if ($comp -> pvc[$real_bas_id]['name']!="") continue;
$tpl -> setVariable(array(
'BAS'	=> $real_bas_info['name'],
'BAS_ID'=> $real_bas_id,
));

 

and here is what i see when i try to dump the REAL_BAS_ID array

 

array(23) {
[7]=> array(1) { ["name"]=> string(11) "value" } 
[14]=> array(1) { ["name"]=> string(12) "value" } 
[23]=> array(1) { ["name"]=> string(13) "value" } 
[1]=> array(1) { ["name"]=> string(17) "value" } 
[20]=> array(1) { ["name"]=> string(18) "value" } 
[6]=> array(1) { ["name"]=> string(15) "value" } 
[13]=> array(1) { ["name"]=> string(16) "value" } 
[10]=> array(1) { ["name"]=> string(11) "value" } 
[19]=> array(1) { ["name"]=> string(12) "value" } 
[9]=> array(1) { ["name"]=> string(6) "value" } 
[17]=> array(1) { ["name"]=> string(7) "value" } 
[3]=> array(1) { ["name"]=> string(9) "value" } 
[21]=> array(1) { ["name"]=> string(10) "value" } 
[8]=> array(1) { ["name"]=> string(10) "value" } 
[15]=> array(1) { ["name"]=> string(11) "value" } 
[4]=> array(1) { ["name"]=> string( "value" } 
[16]=> array(1) { ["name"]=> string(9) "value" } 
[5]=> array(1) { ["name"]=> string(7) "value } 
[12]=> array(1) { ["name"]=> string( "value" } 
[22]=> array(1) { ["name"]=> string(9) "value" } 
[11]=> array(1) { ["name"]=> string(4) "value" } 
[2]=> array(1) { ["name"]=> string(7) "value" } 
[18]=> array(1) { ["name"]=> string( "value" } 
}

What is in $comp->pvc ?  If it is not an array, then that is probably the cause of the error.  The error is often caused like this:

 

$foo = 'bar';
print $foo[0]; # OK, treating a string as a 1 level array gives you a string offset instead
print $foo[0][0]; # Error!  Can't treat a string as a 2 level array

Wow !! thanks a ton !!

 

The problem is exactly that -

comp->pvc

is

string(5) "EMPTY"
