我正在检索＆＃34; src_big＆＃34;：＆＃34; http：//cs628628.vk.me/v628628040/41d82/q2EumplfhhM.jpg"例如。但是这个图像，而不是https：//，我需要通过一组规则转换为https。

你可以看到我有类似的＆＃34; c629401＆＃34;我需要改变

到

https://pp.vk.me/c629401/

此图像可以使用其他链接，例如

Answer 1

使用preg_match的代码应该没问题：

<?php
    $imgurl = "http://cs629401.vk.me/v629401896/3e689/pT5Z5oukzIE.jpg";
    $toremove = Array("s", "S");
    preg_match("#http://(.+)\.vk\.me/(.+)#", $imgurl, $matches);
    $simgurl = "https://pp.vk.me/" . str_replace($toremove, "", $matches[1]) . "/" . $matches[2];

    echo $simgurl . "\n";

您可以将其包装在函数中以转换网址：

<?php

function convertUrl($url)
{
    $toremove = Array("s", "S"); // Letters to remove from matches[1] group
    preg_match("#http://(.+)\.vk\.me/(.+)#", $url, $matches);
    return "https://pp.vk.me/" . str_replace($toremove, "", $matches[1]) . "/" . $matches[2];
}

echo convertUrl("http://cs629401.vk.me/v629401896/3e689/pT5Z5oukzIE.jpg") . "\n";

https://pp.vk.me/c629401/v629401896/3e689/pT5Z5oukzIE.jpg
