What common mistake is made in the PHP code provided that prevents the if statement from executing properly?

The common mistake made in the PHP code provided is the incorrect syntax of the if statement. The condition within the if statement is using a single equal sign (=) for comparison instead of a double equal sign (==) or triple equal sign (===). This results in assignment instead of comparison, causing the if statement to not execute properly. Corrected PHP code snippet: 

<?php
$number = 10;

if ($number == 10) {
    echo "The number is 10.";
} else {
    echo "The number is not 10.";
}
?>
