PHP SQL Select Where
PHP SQL Select Where is used to provide the records from the table that meet
the specific criteria and print the records on the browser. The Where Clause
helps you to return only those records that meet the specific criteria in the
SQL query.
Understand with Example
This section of Tutorial illustrate an example from 'PHP SQL Select Where'.
To understand and grasp the example we create a table user. The select Query is
used to return the records from table 'user'.
Table: user
In order to execute the query in PHP, we create a where.php. The
Where.php uses the mysql_query () function. This function helps you to send the
query or command to a MySQL connection. The Mysql_query () function create a
mysql query "SELECT * FROM user WHERE fname='sandeep'",
which select all the records from "user" where fname=
"sandeep". The While loop tells PHP to execute the statement
repeatedly, till the while expression evaluate all the records of 'sandeep' from
table 'user'. The echo , property of PHP is used to print the records on
the browser.
