How can PHP beginners effectively troubleshoot issues with array replacement in a string?

When replacing array values in a string in PHP, beginners may encounter issues due to improper syntax or incorrect usage of functions like `str_replace` or `preg_replace`. To effectively troubleshoot these issues, beginners should carefully check the syntax of their replacement code, ensure the array values are correctly formatted, and verify that the replacement function is being applied correctly.

// Example code snippet for replacing array values in a string
$string = "Hello [name], welcome to [place]!";
$replacements = array(
    '[name]' => 'John',
    '[place]' => 'Paris'
);

foreach($replacements as $key => $value){
    $string = str_replace($key, $value, $string);
}

echo $string;
