测试代码如下:
$int = 135893597710;print_r($int);print_r(array($int=>1));
输出结果在windows上是135893597710Array ( [-1545355762] => 1 )
到linux的时候就能得到正确的结果135893597710Array ( [135893597710] => 1 )
请问如何可以在windows上得到正确的结果
回复讨论(解决方案)
<?php$int = '135893597710';print_r($int);print_r(array($int=>1));?>
现在的问题是,生产服是linux,里面有一批数据是serialize处理后存储的,现在我导到本地后,没办法还原,因为里面有些数组的下标就是这种很大的数字。所以,如果我想在本地使用生产服的数据抢建测试环境,必须解决上面的测试代码的输出问题
你的 linux 是 64 位的?似乎也不应该出现这种问题
先不去管他吧,等有 64位 linux 的朋友测试以后再说
假定序列化后的是这样的串:a:1:{i:135893597710;i:123;}
则有
$s = 'a:1:{i:135893597710;i:123;}';$s = preg_replace_callback('/i:(\d{10,});/', function($r) { return sprintf('s:%d:"%s";', strlen($r[1]), $r[1]); }, $s); //将大整数改成字符串print_r(unserialize($s)); //检查反序列化结果Array
(
[135893597710] => 123
)
生产服是Linux64位,但是我的windows也是64位呀,我还把php也换成64位的,未遂
目前决定先用楼上的办法吧,毕竟只是测试环境,能用就好了,先不纠结了。不过如果有朋友能找到真正的原因更好~
你的windows也是64位的?那么你能自己编译 php 吗?
php 并没有发行 for window 的 64位版本
php有第三方编译的x64
不过
测试最大int仍然是2^32-1 (win7 x64)
你的windows也是64位的?那么你能自己编译 php 吗?
php 并没有发行 for window 的 64位版本
我自己编译的64位php和网上下载的wamp64位版本,都不行
既然你能自己编译 php,那么请检查一下 64位编译开关打开没有
另外一定是要 VC9 以上的编译器,最好是 VC10 以上的

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
