How can PHP developers ensure that their code accurately counts characters up to a specific word in a string?

PHP developers can accurately count characters up to a specific word in a string by using the `strpos()` function to find the position of the target word in the string. They can then use `substr()` to extract the substring up to that position and finally use `strlen()` to count the characters in that substring. 

$string = "This is a sample string for counting characters up to a specific word";
$word = "string";

$position = strpos($string, $word);
$substring = substr($string, 0, $position);
$character_count = strlen($substring);

echo "Character count up to the word '$word' is: $character_count";
