So, I'm creating a system that searches and displays results from a MySQL table database, and I'm trying to figure out how to store the result inside a php variable so I can format and process it rather than using a printf
function. However, it doesn't seem to understand what I am putting inside the variable:
<?php
if(isset($_POST['submit']))
{
if(isset($_GET['go']))
{
if(preg_match("/[A-Z | a-z | 0-9]+/", $_POST['search-input']))
{
$searchcondition=$_POST['search-input'];
//connect to the database
$database = "mysql";
$hostname = "localhost";
$link = new mysqli($hostname, "root", "", $database);
//$link = mysqli_connect($hostname, "root", "", $database);
if (!$link)
{
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
$query1 = "SELECT `Title`, `Date` FROM `search-database` WHERE `Title` LIKE '%" . $searchcondition . "%' ";
//$query1 = "SELECT `ID`,`FirstName`, `LastName`, `Email`, `PhoneNumber` FROM `test` WHERE `FirstName` LIKE '%" . $searchcondition . "%' AND `Email` LIKE '%" . $searchcondition . "%' ";
if ($result = $link->query($query1))
{
/* fetch associative array */
while ($row = $result->fetch_assoc())
{
$string = '$row["Title"], $row["Date"]';
echo $string;
/* The $string variable above is not recognizing what I just put above. When I do no single quotes, it gives an error. When I do put single quotes, it prints out the actual characters "$row["Title"], $row["Date"]" rather than what the variables actually store.
here is the Original Code (which does work):
printf ("%s, %s, %s, %s, %s\n", $row["ID"], $row["FirstName"], $row["LastName"], $row["Email"], $row["PhoneNumber"]);
*/
}
/* free result set */
$result->free();
}
mysqli_close($link);
}
else
{
echo "<p>Please enter a search query</p>";
}
}
}
?>
The $string variable above is not recognizing what I placed inside it. When I don't put in single quotes, it shows an error. When I do put single quotes, it prints out the actual characters $row["Title"]
, $row["Date"]
rather than what the variables actually store.
Here is the Original Code (which works):
printf ("%s, %s\n", $row["Title"], $row["Date"]);
How do I get the php to display the same as the original printf function except by echoing a separate variable ($string) storing the printf
contents, or is there an easier way to display the information and still be able to format it easily?
I would just put a comment but I don't have enough points. Would this not sufficient ?
<?php
$string = $row["Title"] . ", " . $row["Date"];
echo $string;
?>
you may concat any no of variables like below.
while ($row = $result->fetch_assoc())
{
echo $string = $row["Title"].','. $row["Date"].'\n';
}
If you already have printf
, consider using sprintf , which is similar to printf
, but stores the result in a variable instead of printing it:
<?php
....
$string = sprintf ("%s, %s\n", $row["Title"], $row["Date"]);
....
Single quote is not needed in this case. Since you need "," in between the Strings, you can write the code like this
$string = $row["Title"].",". $row["Date"];
