字符串匹配没有匹配php中的字符顺序

Question

我正在尝试在php中创建一个条件，如下所示 -

$variable = "132";
if($variable == "123"){
    echo "Matched.";
}else{
    echo "Not Matched.";
}

我想在这种情况下显示匹配，导致这两个值是相同的字符。

Answer 1

非常感谢你，最后我得到了答案 -

$variable = "1432";
$var = str_split($variable);
sort($var);
if(implode("", $var) == "1234"){
    echo "Matched.";
}else{
    echo "Not Matched.";
}

Answer 2

我会将字符串拆分为组成字符，并对它们执行array_diff。

$variable = str_split("132");
$variable_2 = str_split("123");
var_dump( array_diff($variable, $variable_2));
if(count(array_diff($variable, $variable_2)) == 0){
    echo "Matched."; 
}else{
    echo "Not Matched.";
}
