What are common mistakes to avoid when working with loops and echoing content in PHP?

One common mistake to avoid when working with loops and echoing content in PHP is forgetting to concatenate strings properly within the loop. This can lead to unexpected output or errors in the code. To solve this issue, make sure to use the concatenation operator (.) to combine strings within the loop before echoing them. 

// Incorrect way of echoing content within a loop
for ($i = 1; $i <= 5; $i++) {
    echo "Number: $i";
}

// Correct way of echoing content within a loop
for ($i = 1; $i <= 5; $i++) {
    echo "Number: " . $i;
}
