What are common issues when using mysql_fetch_array within a function in PHP?

Common issues when using mysql_fetch_array within a function in PHP include scope issues with the result set variable and potential conflicts with other functions or variables. To solve this, you can pass the result set variable as a parameter to the function or use the global keyword to access it within the function.

// Example of passing result set variable as a parameter to the function
function processResult($result) {
    while ($row = mysql_fetch_array($result)) {
        // Process each row
    }
}

// Example of using the global keyword to access the result set variable within the function
function processResult() {
    global $result;
    while ($row = mysql_fetch_array($result)) {
        // Process each row
    }
}
