What potential issues can arise when using arrays to replace values in a PHP template?

When using arrays to replace values in a PHP template, one potential issue that can arise is if the array key does not exist in the template. This can lead to errors or unexpected behavior in the output. To solve this issue, you can check if the array key exists before replacing the value in the template. 

// Example array with values to replace in the template
$data = [
    'name' => 'John Doe',
    'age' => 30
];

// Example template with placeholders
$template = 'Hello, {name}. You are {age} years old.';

// Loop through the data array and replace placeholders in the template
foreach ($data as $key => $value) {
    if (strpos($template, '{' . $key . '}') !== false) {
        $template = str_replace('{' . $key . '}', $value, $template);
    }
}

// Output the modified template
echo $template;
