MySQL Convert in PHP
In this article I explain MySQL convert function in PHP.
CONVERT Function
The MySQL convert function is used to mutate a value of one type (data type) to another type. In other words, the CAST() function takes a value of one type and produces a value of another type. Basically the cost and convert functions do the same thing but there is a little difference between the cast and convert functions.
Syntax
The "Type" can have the following values:
- Binary
- Char
- Date
- DateTime
- Decimal
- Signed [integer]
- Time
- Unsigned [integer]
Example of CONVERT Function with PHP
<?php
$con=mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mysql", $con);
print "<h2>MySQL: Convert Function</h2>";
$result = mysql_query("select CAST(emp_JoinDate as Date) As JoinDate from mcnemployee;");
echo "<table border='1'>
<tr>
<th>EmpJoinDate</th>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<td>" . $row['JoinDate'] . "</td>";
echo "</tr>";
}
echo "</table>";
?>
Output
