How can the issue of colliding data types be resolved when generating an alias column in PHP?

When generating an alias column in PHP, the issue of colliding data types can be resolved by explicitly casting the data types to match before combining them. This ensures that the resulting alias column has a consistent data type.

// Example code to resolve colliding data types when generating an alias column
$number = 10;
$string = "20";

// Explicitly cast the data types to match before combining them
$alias_column = (int)$number + (int)$string;

echo $alias_column; // Output: 30
