What common syntax error related to logical operators can occur in PHP scripts, as seen in the provided code snippet?

The common syntax error related to logical operators in PHP scripts is using the bitwise operator '&' instead of the logical operator '&&' for a logical AND operation. The '&' operator is used for bitwise operations on integers, while '&&' is used for logical operations on boolean values. To fix this issue, ensure that logical operators are used correctly in conditional statements to avoid unexpected behavior in the script.

// Incorrect usage of bitwise operator '&' instead of logical operator '&&'
$var1 = true;
$var2 = false;

if($var1 & $var2) {
    echo "This will not be executed.";
}

// Corrected usage of logical operator '&&'
if($var1 && $var2) {
    echo "This will not be executed.";
}
