What are some common errors that can occur when trying to unset string offsets in PHP arrays?

When trying to unset string offsets in PHP arrays, a common error is "Cannot unset string offsets" because PHP arrays cannot have string keys unset using the unset() function. To solve this issue, you can use the array_splice() function to remove elements by their keys. 

<?php
// Create an associative array with string keys
$array = array("key1" => "value1", "key2" => "value2", "key3" => "value3");

// Remove element with key "key2"
unset($array["key2"]);

// Output the updated array
print_r($array);
?>
