So the reason you get the Undefined offset: x error is because of the order in which PHP evaluates the code., 2 @christophetd Only in Laravel 4.x, Laravel 5 escapes HTML by default (when double brackets are used) – lukasgeiter Apr 12 '15 at 12:46 ,isset() will check if title on the object is set, but to do so, it will require $blogs[0] to be a valid object. In order to do that, it will try and get the object from the $blogs array at index 0. But since this index does not exist, it will trigger the Exception with an Undefined offset: 0. , Physical effects of strong magnets under skin?

Try the following:

{
   {
      isset($blogs[0]) ? $blogs[0] - > title : ''
   }
}

If you are using a foreach to get every $blog->title use

@foreach($blogs as $blog) {
   {
      $blog - > title
   }
}
@endforeach

How to avoid undefined offset error in PHP ?,There are some methods to avoid undefined offset error that are discussed below:  ,empty() function: This function checks whether the variable or index value in an array is empty or not.,The Offset that does not exist in an array then it is called as an undefined offset.

This error means that within your code, there is an array and its keys. But you may be trying to use the key of an array which is not set.,This type of error occurs with arrays when we use the key of an array, which is not set.,The error can be avoided by using the isset() method. This method will check whether the declared array key has null value or not. If it does it returns false else it returns true for all cases.,In the following, given an example, we are displaying the value store in array key 1, but we did not set while declaring array “$colorarray.”

Error Example:

< ? php
// Declare an array with key 2, 3, 4, 5
$colorarray = array(2 => 'Red', 3 => 'Green', 4 => 'Blue', 5 => 'Yellow');
// Printing the value of array at offset 1.
echo $colorarray[1]; ?

You make assumptions about that index being present, which may not always be the case. Your logic should be more thussly:

$st = isset($stay[0]) ? $stay[0] : false;
if ($st) {
   //now you can use it safely.
}
