Question

嘿,伙计们,这是我的php:

$x = array("one", "two", "three");
foreach ($x as $value)
{
  if ($value !=  one  && $value !=  two )
  {
    echo $value . "<br />";
  }
}

这只回响了三个字。我不得不使用 $value! = 1 & amp; & amp; $value! = 2 来做到这一点, 我在想我是否可以将它合并成类似的东西 :

if ($value !=  one, two )

那行不通所以我想你们能不能帮个忙

Answer 1

if (!in_array($value, array( one ,  two )))
  echo $value;

Answer 2

你可以创建一个切换语句让它看起来更漂亮, 但这是你所能做到的。

switch ($i) {
    case "one":
    case "two":
    case "three":
        echo $value .  <br/> ;
        break;
}

Answer 3

if you need to print or do certain operation when value == three then only look for value == three

  foreach ($x as $value) 
 {
      if($value === "three")
      echo $value;
 }

also you can take a look at using === operator to compare strings. since == uses type juggling while === enforces same type (2 strings, 2 int no mixing) link: http://www.php.net/manual/en/language.operators.comparison.php

Answer 4

全部跳过前台 :

$x=array("one","two","three");
$exclude=array("one","two");

print_r(array_diff($x, $exclude));

Answer 5

if ($value ==  three )

也许这个?
