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
<?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;
}
?>
