[Check if column within MySQL database contains a string.]

How corny. Might be rice to learn it.

 

$pdo is not defined. The error tells you. Look at your code carefully, what is $pdo?

 

 

 

<?php


try {
$username = '******';
$password = '*****';
    $conn = new PDO('mysql:host=5;dbname=*****', $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    echo 'ERROR: ' . $e->getMessage();
}
$stmt = $conn->prepare('SELECT COUNT(*) FROM wordlist WHERE words LIKE :aword');
$stmt->execute(array('aword' => "%{$_GET['word']}%"));
return ($stmt->fetchColumn() != 0);
?>
 

 

Sorry for the obvious mistake...

 

How exactly would I make it echo true or false if the database contains the string though?

[Check if column within MySQL database contains a string.]

Okay, so basically what I want to is create an API using PHP which will allow my program to check if a column within a table contains a certain string.

 

For example,

Say I enter 

 

    www.mywebsite.com/api.php?word="ANY WORD"

 

The script would echo true or false if the database contained that word or not.

 

I am using a MySQL database and I have no idea how to go about this.

   <?php


    try {
 $username = '******';
 $password = '******';
      $conn = new PDO('mysql:host=******;dbname=**********', $username, $password);
      $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
   
    } catch(PDOException $e) {
    
    echo 'ERROR: ' . $e->getMessage();
    
    }


      $stmt = $pdo->prepare('SELECT COUNT(*) FROM wordlist WHERE words LIKE :aword');
      $stmt->execute(array('aword' => "%{$_GET['word']}%"));
      return ($stmt->fetchColumn() != 0);
    ?>



 

 

 

What did I do wrong? I get this error

 

     Fatal error: Call to a member function prepare() on a non-object in ***** on line 11

 

I barley know PHP....
