Scalar values as an array

[breWtal]

the below piece of code, keeps giving me these 2 errors: Cannot use a scalar value as an array in /homepages/**/**********/******/***/******/garage.php  on line 41. 

 

and

 

Invalid argument supplied for foreach() in /homepages/**/**********/******/***/******/garage.php  on line 151.

 

 

Can anyone please help me fix these 2 issues?

[Ken2k7]

On line 11, you first declared and initialized $cars to be of type int.

$cars=$db->num_rows($q);

 

Then on line 41, you used $cars as an array, so PHP complains about it.

 

The second error is the same because $cars is NOT an array so you can't loop through it.

Wait, you coded all that but you don't know how to fix a simple variable naming issue? Just change the name of the variables.

[breWtal]

no, i didnt code it, i wish i had, i wouldnt have these probs if i did lol
