PHP Tutorial for Beginners in Urdu/Hindi: 06 Interesting Facts of Prepared statements using PDO


Hello Friends, Welcome to another PHP Tutorial for Beginners in Urdu/Hindi. Today in This PHP Tutorial for Beginners we are going to see Interesting Facts of Prepared statements using PDO. Many of the more mature databases support the concept of prepared statements. What are they? They can be thought of as a kind of compiled template for the SQL that an application wants to run, that can be customized using variable parameters. Prepared statements offer two major benefits: The query only needs to be parsed (or prepared) once but can be executed multiple times with the same or different parameters. When the query is prepared, the database will analyze, compile, and optimize its plan for executing the query. For complex queries, this process can take up enough time that it will noticeably slow down an application if there is a need to repeat the same query many times with different parameters. By using a prepared statement the application avoids repeating the analyze/compile/optimize cycle. This means that prepared statements use fewer resources and thus run faster. The parameters to prepared statements don't need to be quoted; the driver automatically handles this. If an application exclusively uses prepared statements, the developer can be sure that no SQL injection will occur (however, if other portions of the query are being built up with unescaped input, SQL injection is still possible). Prepared statements are so useful that they are the only feature that PDO will emulate for drivers that don't support them. This ensures that an application will be able to use the same data access paradigm regardless of the capabilities of the database Friends, agar meri explanation main koi cheez aap ko samaj nah aa rahi ho to aap neechay comment kar saktay hain taa k main next video main pehlay usay explain karoon phir next vide tutorial ko start karoon.
