我是PHP的新手,我正在尝试编写一个带有两个变量的简单函数,如果变量相同则返回字符串“match”,如果它们不同则返回“no_match”。再次编程新手,所以提前感谢!!

您不需要执行此操作的功能:
$result = ($var1 === $var2) ? "match" : "no_match";
但如果你坚持:
function matches($var1, $var2, $strict = false) {
return ($strict ? $var1 === $var2 : $var1 == $var2) ? "match" : "no_match"
}
用法:
$v1 = 1;
$v2 = "1";
var_dump(matches($v1, $v2)); //match
var_dump(matches($v1, $v2, true)); //no_match
$v1 = "1";
var_dump(matches($v1, $v2, true)); //match

/**
* Compare two values for equality/equivalence
* @param mixed
* @param mixed
* @param bool compare equivalence (types) instead of just equality
* @return string indicating a match
*/
function compare($one, $two, $strict = false) {
if ($strict) {
$compare = $one === $two;
}
else {
$compare = $one == $two;
}
if ($compare) {
return 'match';
}
else {
return 'no_match';
}
}
