What is the potential issue with using strpos() to check for a specific character in a string in PHP?

The potential issue with using strpos() to check for a specific character in a string in PHP is that it returns the position of the first occurrence of the character, which may lead to unexpected results if the character appears multiple times in the string. To solve this, you can explicitly check if the character exists in the string by using the strict comparison operator (===) to ensure that the character is found at the beginning of the string. 

$string = "hello world";
$char = "h";

if ($string[0] === $char) {
    echo "The character '$char' is found at the beginning of the string.";
} else {
    echo "The character '$char' is not found at the beginning of the string.";
}
