This is true for almost any language and almost any case; you should protect your My SQL code from sql-injections, your php input fields from scripts, your javascript from infinite loops, your java code from non-fitting variable type.Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. This is a primitive value, not a reference to an object.
