How can the use of unnecessary conditions, such as the if($i=='Z') break; statement, impact the performance of a loop in PHP?

Using unnecessary conditions like the if($i=='Z') break; statement can impact the performance of a loop in PHP by introducing additional checks that are not needed. This can lead to unnecessary evaluations within the loop, potentially slowing down its execution. To solve this issue, it is important to only include conditions that are necessary for the logic of the loop. 

// Example of a loop without unnecessary conditions
for ($i = 0; $i < 10; $i++) {
    // Loop logic here
}
