PHP Insert into PostgreSQL

So it’s probably a really stupid/basic question, but i have this simple PHP function (which works) and inserts data into a PostgreSQL DB.

My issue is when it encounters specific data;

function insertData($pg, $csvfile)
      {
        $x = 0;
        foreach ($csvfile as $data)
        {
          $email = $csvfile[$x]['email'];
          $name = $csvfile[$x]['name'];
          $surname = $csvfile[$x]['surname'];
          $query = "INSERT INTO users (email, name, surname) VALUES ('$email', '$name', '$surname')";
          $result = pg_query($pg, $query);
          $x++;
        }
      }

And while this works, it falls over with a surname such as:

O’hare

And obviously this occurs because then the PHP code comes out as:

…VALUES (‘[e-mail]’, ‘John’, ‘O’hare’)”;

but im not sure of how i should be structuring the PHP to allow for this.

Answer

Try this:

function insertData($pg, $csvfile) {
    $nbr = count(file($csvfile));   
    for($i=0; $i<$nbr; $i++) {
      $email = pg_escape_string( $csvfile[$i]['email'] );
      $name = pg_escape_string( $csvfile[$i]['name'] );
      $surname = pg_escape_string( $csvfile[$i]['surname'] );
      $query = "INSERT INTO users (email, name, surname) VALUES ('$email', '$name', '$surname')";
      $result = pg_query($pg, $query);
      if (!$result) {
        echo "Error while executing the query: " . $query;
        exit;
      }
    }
}
