New to PHP 7: mysqli_fetch_assoc not working


Recommended Posts



I'm just changing all my old PHP 5 code to PHP 7, which I'm very new to, and have come across some issues. The below code is giving this error: Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in


Any help much appreciated:


$sql = "SELECT * FROM content WHERE `live` LIKE '0' AND `featured` LIKE '1'";
$result = mysqli_query($con, $sql);

Thanks, but do you know why it's failing? It works fine in PHP 5

No, but it does.


Check the value in mysqli_error


Also you use of LIKE is incorrect. LIKE is for matching with wildcard characters (eg WHERE lastname LIKE 'Jon%' to find names beginning with "Jon". You should be using "="

SELECT * FROM content WHERE `live` = 0 AND `featured` = 1;

or even

SELECT * FROM content WHERE NOT `live` AND `featured`;

Secondly, avoid "SELECT STAR" - specify the columns you want returned.
