How can an if-else statement lead to an infinite loop in PHP?

An if-else statement can lead to an infinite loop in PHP if the condition inside the if statement is never met and the else statement always executes. This can happen if the condition is not properly defined or if the logic is incorrect. To solve this issue, ensure that the condition in the if statement is properly defined and that it can eventually be met to exit the loop. 

// Example of how an if-else statement can lead to an infinite loop
$counter = 0;

while ($counter < 5) {
    if ($counter > 10) {
        echo "Counter is greater than 10";
    } else {
        echo "Counter is less than or equal to 10"; // This else statement will always execute, leading to an infinite loop
    }
    $counter++;
}
``` 

To fix the issue, adjust the condition in the if statement to ensure that it can eventually be met to exit the loop.

```php
// Fixing the infinite loop by adjusting the condition in the if statement
$counter = 0;

while ($counter < 5) {
    if ($counter > 5) {
        echo "Counter is greater than 5";
    } else {
        echo "Counter is less than or equal to 5"; // This will now execute until the counter reaches 5
    }
    $counter++;
}
