Show Record From database using PHP and MYSQL using Table Format



We will use the select queries to select a record from the database.
select * from tablename;
PHP provides three different functions to display a record from the database.
1)  mysqli_fetch_array():-  It is used to show record using associative array and index array pattern.
while($var = mysqli_fetch_array($result)
{
   echo $var['columnname'];  // we can write column name also to display data 
   echo $var[index]   // we can write index also where first column index start from 0
}
We always use the while loop to display a record from the database and the while loop will be true until condition false.
Example with complete PHP Code-
<?php
$conn = mysqli_connect('localhost',"root","","php12batch");
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_array($res))
{
echo $x[0]. " ".$x[1]." ".$x[2]." ".$x[3]. " ".$x[4];
}
?>
Example with complete PHP Code-
<?php
$conn = mysqli_connect('localhost',"root","","php12batch");
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_array($res))
{
echo $x['rno']. " ".$x['name']." ".$x['branch']." ".$x['fees']. " ".$x['mobile'];
}
?>
2) mysqli_fetch_row():-  It is used to show record using index array
It is used to display a single row using an index array pattern.
We can display data without using Loop.
$var = mysqli_fetch_row($result);
echo $var[0];  //0 is the index
Example with complete PHP Code-
<?php
$conn = mysqli_connect('localhost',"root","","php12batch");
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_row($res))
{
echo $x[0]. " ".$x[1]." ".$x[2]." ".$x[3]. " ".$x[4];
}
?>
3) mysqli_fetch_assoc():-  It is used to display data using an associative array.
while($var = mysqli_fetch_assoc($result)
{
   echo $var['columnname'];  // we can write column name also to display data 
   echo $var[index]   // we can write index also where first column index start from 0
}
Example with complete PHP Code-
<?php
$conn = mysqli_connect('localhost',"root","","php12batch");
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_assoc($res))
{
echo $x['rno']. " ".$x['name']." ".$x['branch']." ".$x['fees']. " ".$x['mobile'];
}
?>
4) mysqli_fetch_object():-  It is used to display data using object pattern;
while($var = mysqli_fetch_object($result)
{
   echo $var->columnname;  // we can write column name also to display data 
  }
Example with complete PHP Code-
<?php
$conn = mysqli_connect('localhost',"root","","php12batch");
$res = mysqli_query($conn,"select * from student");
while($x = mysqli_fetch_object($res))
{
echo $x->rno. " ".$x->name." ".$x->branch." ".$x->fees. " ".$x->mobile;
}
?>

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
