What potential issue did the user face with the if statement in the code?

The potential issue the user faced with the if statement in the code is that the comparison operator used may not be evaluating the condition as expected. To solve this issue, the user should check if the comparison operator used is appropriate for the data types being compared. For example, using '==' for loose comparison or '===' for strict comparison. 

// Potential issue with the if statement
if ($var == '1') {
    // Code block
}

// Fix: Use strict comparison operator '==='
if ($var === '1') {
    // Code block
}
