Are there built-in PHP functions that can be used to search for specific characters in a string?

Yes, there are built-in PHP functions that can be used to search for specific characters in a string. One such function is `strpos()`, which returns the position of the first occurrence of a substring within a string. Another function is `strrpos()`, which returns the position of the last occurrence of a substring within a string. These functions can be used to search for specific characters or substrings within a given string. 

$string = "Hello, World!";
$character = "o";

$position = strpos($string, $character);

if ($position !== false) {
    echo "The character '$character' was found at position: $position";
} else {
    echo "The character '$character' was not found in the string.";
}
