How can the use of the != operator in a MySQL query affect the results in PHP?

Using the != operator in a MySQL query can affect the results in PHP if the query is not properly constructed. It is important to ensure that the query is written correctly to avoid unexpected results. One way to solve this issue is to use the <> operator instead, which also represents "not equal to" in MySQL. 

$query = &quot;SELECT * FROM table_name WHERE column_name &lt;&gt; &#039;value&#039;&quot;;
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) &gt; 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process the data
    }
} else {
    echo &quot;No results found.&quot;;
}
