What potential issues can arise when calculating the total contributions of different user groups in PHP?

One potential issue that can arise when calculating the total contributions of different user groups in PHP is ensuring that the input data is validated and sanitized to prevent any malicious code injection or unexpected values that could affect the calculation. To solve this, you can use PHP functions like filter_var() or intval() to sanitize and validate the input data before performing any calculations. 

// Example of sanitizing and validating input data before calculating total contributions

// Assuming $group1 and $group2 are arrays containing contributions from different user groups

// Sanitize and validate input data
$group1 = array_map('intval', $group1);
$group2 = array_map('intval', $group2);

// Calculate total contributions of each group
$totalGroup1 = array_sum($group1);
$totalGroup2 = array_sum($group2);

// Output total contributions
echo "Total contributions of Group 1: $totalGroup1";
echo "Total contributions of Group 2: $totalGroup2";
