The "illegal offset type" error in PHP typically arises when attempting to access an array element using an object or an array as the index key.
Analyzing the Code:
In the provided code snippet:
- $xml->entry[$i]->source is the array index key.
- $source is a variable that you want to use as the key for the $s array.
If $xml->entry[$i]->source contains an object or array, you will encounter the error because the syntax expects a string, integer, or float as the array index key.
Addressing the Issue:
To resolve this issue, ensure that $xml->entry[$i]->source consistently holds a valid array index key data type (e.g., string). You can do this by inspecting the contents of $xml->entry[$i] to confirm that it contains the desired data structure and that $source is a valid array key.
If you intend to use an object or array as the array index, you can consider using a specialized data structure like a hash map or a key-value store that allows non-scalar types as keys.
