?>Example case-sensitivity
- Case Sensitive is a case where uppercase and lowercase letters are interpreted differently.
- Case Insensitive is a case where uppercase and lowercase letters are interpreted the same.
<?php
$string = 'The lazy fox jumped over the fence';
if (str_starts_with($string, 'The')) {
echo "The string starts with 'The'\n"; // <-- this will show as output
}
if (str_starts_with($string, 'the')) {
echo 'The string starts with "the"'; // this ignored because insensitive
} else {
echo '"the" was not found because the case does not match'; // <-- this will show as output
