$_GET 数组中未设置长 url

Question

我有以下查询字符串：

 [QUERY_STRING] => u=http%3A%2F%2Fnews.yahoo.com%2Fblogs%2Fsideshow%2Fman-fathered-30-kids-needs-break-child-support-140439765.html&t=%3Cp%20id=%22yui_3_4_0_22_1337372504263_287%22%3EAnd%20you%20thought%20Octomom%20had%20her%20hands%20full%E2%80%94a%20Tennessee%20man%20who%20has%20fathered%2030%20children%20is%20asking%20the%20courts%20for%20a%20break%20on%20child%20support.%3C/p%3E%0A%3Cp%20id=%22yui_3_4_0_22_1337372504263_286%22%3EDesmond%20Hatchett,%2033,%20of%20Knoxville%20has%20children%20with%2011%20different%20women,%20%3Ca%20href=%22http://wreg.com/2012/05/16/tn-man-fathers-30-kids-but-cant-support-any/%22%20target=%22_blank%22%3Ereports%20WREG-TV%3C/a%3E.%3C/p%3E%0A%3Cp%20id=%22yui_3_4_0_22_1337372504263_285%22%3EThe%20state%20already%20takes%20half%20his%20paycheck%20and%20divides%20it%20up,%20which%20doesn%27t%20amount%20to%20much%20when%20Hatchett%20is%20making%20only%20minimum%20wage.%20Some%20of%20the%20moms%20receive%20as%20little%20as%20$1.49%20a%20month.%20The%20oldest%20child%20is%2014%20years%20old.%3C/p%3E%0A%3Cp%20id=%22yui_3_4_0_22_1337372504263_284%22%3EHatchett%20explains%20how%20he%20reached%20such%20a%20critical%20mass:%20He%20had%20four%20kids%20in%20the%20same%20year.%20Twice.%3C/p%3E%0A%3Cp%20id=%22yui_3_4_0_22_1337372504263_283%22%3E%3Ca%20href=%22http://www.youtube.com/watch?v=RTZk1y8iaho%22%20target=%22_blank%22%20id=%22yui_3_4_0_22_1337372504263_308%22%3EBack%20in%202009%20when%20Hatchett%20%3C/a%3Ewas%20in%20court%20to%20answer%20charges%20that%20many%20of%20the%20mothers%20were%20not%20receiving%20child%20support,%20he%20had%2021%20children.%20At%20the%20time,%20he%20said%20he%20was%20not%20going%20to%20father%20any%20more%20kids,%20but%20he%20ended%20up%20having%20nine%20more%20in%20the%20past%20three%20years.%3C/p%3E%0A%3Cp%20id=%22yui_3_4_0_22_1337372504263_282%22%3EThe%20state%20cannot%20order%20Hatchett%20to%20stop%20making%20babies.%20He%20hasn%27t%20broken%20any%20laws,%20according%20to%20the%20report.%3C/p%3E

但是，我的 $_GET 数组中唯一的内容如下：

 [u] => http://news.yahoo.com/blogs/sideshow/man-fathered-30-kids-needs-break-child-support-140439765.html

我的 get 请求少于 2k 个字符，服务器收到了整个字符串，所以我不知道会发生什么。

Answer 1

试试这个：

print_r($_GET);

在我的例子中，使用相同的查询字符串我得到了这个结果：

Array
(
    [u] => http://news.yahoo.com/blogs/sideshow/man-fathered-30-kids-needs-break-child-support-140439765.html
    [t] => <p id="yui_3_4_0_22_1337372504263_287">And you thought Octomom had her hands full—a Tennessee man who has fathered 30 children is asking the courts for a break on child support.</p>

)

第二个值在那里。

可能是你的php的配置。

- suhosin.get.max_name_length（默认值：64） 为通过 URL 注册的变量定义变量名称的最大长度。对于数组变量，这是索引前面的名称。

- suhosin.get.max_totalname_length（默认：256） 定义通过 URL 注册时总变量名称的最大长度。对于数组变量，这包括所有索引。

- suhosin.get.max_value_length（默认值：512） 定义通过 URL 注册的变量的最大长度。

伟大的。

Answer 2

如果您仔细查看查询字符串，您将找到问题的原因。

.....140439765.html&t=%3Cp%20id=....

仔细查看html扩展后的&。 在将其传递给您的 php 脚本之前，您需要在整个 url 中使用 urlencode。

echo '<a href="script.php?u=' . urlencode($link) . '">The link title</a>'

应该可以的。
