检查最后一个字符是“s”还是“z”

编程问答 2022-05-22

问题描述

是否有比以下更大胆的方法来检查最后一个字符是“s”还是“z”：

if (substr($var,-1,1) == "s" OR substr($var,1) == "z") ...

类似的东西

if (substr($var,1) == "s" OR "z") ...

会很好，但 PHP 中有这样的东西吗？

解决方法

使用 in_array 并查找数组中的最后一个字符：

if (in_array(substr($var,-1,1),['s','z']))
,

或者：

in_array(array_pop(explode('',$var)),'z'])` ?

不是更可读也不是英勇，但我知道什么？ :)

厌倦了太容易理解的代码？正则表达式来拯救：

<?php

$service_url = 'https://********/PostRequest';
$curl = curl_init($service_url);

//collection Object
$data = array(
    'request' => array(
        "Key1" => "*****","key2" => "","key3" => "****","key4" => "****","key5" => "****","key6" => "****","key7" => "***","key8" => "****","key9" => "***","key10" => "****","key11" => "***","ItemList" => array(

            "subkey1" => "***","subkey2" => "***","subkey3" => "****","subkey4" => "****","subkey5" => "****","subkey6" => "*****","subkey7" => "***","subkey8" => "***","subkey9" => "***","subkey10" => "**","Subkey11" => "**","subkey12" => "**","subkey13" => "04","subkey14" => "010101","Subkey15" => "R","Subkey16" => "70","Subkey17" => array(
                "string" => "00"
            )
        ),"Address" => array(
            "PrimaryAddressLine" => "","SecondaryAddressLine" => "","County" => "","City" => "","State" => "","PostalCode" => "****","Plus4" => "","Country" => "","Geocode" => "","VerifyAddress" => "false"
        ),)
);


 $data_json = json_encode($data);
// Set the CURLOPT_RETURNTRANSFER option to true
curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);

// Set the CURLOPT_POST option to true for POST request
curl_setopt($curl,CURLOPT_POST,true);

// Set custom headers for RapidAPI Auth and Content-Type header
curl_setopt($curl,CURLOPT_HTTPHEADER,array('Content-Type: application/x-www-form-urlencoded')); 

curl_setopt($curl,CURLOPT_POSTFIELDS,$data_json);

$response = curl_exec($curl);
curl_close($curl);

print_r($response);



die();

如果您能够使用 PHP8，那么您应该可以在 PHP8 中使用这个简单的解决方案。

https://www.php.net/manual/en/function.str-ends-with.php

<?php
$text = 'foods';
if (str_ends_with($text,'s') || str_ends_with($text,'z')) { ... }
strstr
