What are the potential pitfalls of using "or" instead of "and" in conditional statements in PHP?

Using "or" instead of "and" in conditional statements in PHP can lead to unintended behavior because "or" evaluates to true if either condition is true, while "and" requires both conditions to be true. To fix this issue, make sure to use "and" when you want both conditions to be true for the statement to execute correctly. 

// Incorrect usage of "or"
if ($condition1 == true or $condition2 == true) {
    // This block will execute if either $condition1 or $condition2 is true
}

// Corrected usage of "and"
if ($condition1 == true and $condition2 == true) {
    // This block will only execute if both $condition1 and $condition2 are true
}
