URL中带有空格的file_get_contents [英] file_get_contents with spaces in URL

问题描述

我有一个问题，即使我将空格替换为％20并获得此内容，浏览器获得的最终URL也会将％20"变为％2520"

I have an issue where even if I replace the spaces to %20 and get this content the ultimate url the browser gets turns the "%20" into "%2520"

这是我的代码，有什么建议可以使其正常工作吗?似乎很容易，但是我被卡住了:/

Here's my code, any suggestions to get this to work? it seems easy but I'm stuck :/

<?php
//$_GET['song'] will contain a song name with spaces
$song = str_replace(array("%20", "&", "?" , "/"), array(" ", "", "", ""), $_GET['song']);

// I use this to check how the GET 'song' looks after the str_replace
$list = "http://www.lyrdb.com/lookup.php?q=" . $song . "&for=fullt";
echo "list url is " . $list . "<hr>";

$content = file_get_contents("http://www.lyrdb.com/lookup.php?q=" . str_replace(" ", "%20", $song) . "&for=fullt");

echo $content;
?>

如果您访问 http://webservices.lyrdb.com/lookup.php?q=red%20hot%20chili%20peppers&for=fullt 结果应输出一个歌词列表.

if you go to http://webservices.lyrdb.com/lookup.php?q=red%20hot%20chili%20peppers&for=fullt The result should output a list of lyric codes.

当我访问我的网站/?song = red hot chili peppers时，它也将空格转换为％20，但是如果浏览器似乎将％转换为％25.

When i go to my website /?song=red hot chili peppers , it too converts spaces to %20 's but if it seems the browser converts the %'s to %25.

有人可以帮我吗?

推荐答案

$song = $_GET['song']);

$url = "http://www.lyrdb.com/lookup.php?for=fullt&q=";

echo "list url is " . htmlentities($url . $song) . "<hr>";

$content = file_get_contents($url . urlencode($song));

echo $content;
