问题描述
想不通什么是错在这里。阅读乡亲在这里说什么：<一href=\"http://informationideas.com/news/2006/06/14/fatal-error-cannot-use-string-offset-as-an-array-in/\" rel=\"nofollow\">http://informationideas.com/news/2006/06/14/fatal-error-cannot-use-string-offset-as-an-array-in/在这里：不能使用字符串作为PHP中的数组
我的print_r（） -ed中的实际值 $项目（从谷歌日历来），他们无一不精。
的foreach（$条目$ E）{
$信息=阵列（）; //添加看看是否pre-声明帮助
$信息=阵列（
$ E ['标题']，
$ E ['的gd：当ATTR'] ['的startTime']，
$ E ['的gd：其中attr'] ['的valueString']，
$ E ['内容']
）;
}
我在做什么错了？

解决方案
我敢打赌，要么
- $项不是数组
-
$è中的一个或多个不阵列
尝试
的foreach（$条目$ E）{
$信息=阵列（）; //添加看看是否pre-声明帮助
如果（is_array（$ E））//只有去当$Ë实际上是一个数组
$信息=阵列（$ E ['标题']，
$ E ['的gd：当ATTR'] ['的startTime']，
$ E ['的gd：其中attr'] ['的valueString']，
$ E ['内容']）;
}
如果你想这样做真的很不好，你检查 $è（startTime时等）首先使用的每个键使用isset （）或 array_key_exists（）。
Can't figure what is wrong here. Read what folks are saying here: http://informationideas.com/news/2006/06/14/fatal-error-cannot-use-string-offset-as-an-array-in/ and here: Cannot use string offset as an array in php
I have print_r()-ed the actual values in $entries (coming from Google Calendar) and they are all fine.
foreach ( $entries as $e ) {
$info = array(); // added to see if pre-declaration helps
$info = array(
$e[ 'title' ],
$e[ 'gd:when attr' ][ 'startTime' ],
$e[ 'gd:where attr' ][ 'valueString' ],
$e[ 'content' ]
);
}
What am I doing wrong?

解决方案
My bet is that either
- $entries is not an array
- one or multiple of
$eare not arrays
try
foreach ( $entries as $e ) {
$info = array(); // added to see if pre-declaration helps
if (is_array($e)) // only go on if $e is actually an array
$info = array( $e[ 'title' ],
$e[ 'gd:when attr' ][ 'startTime' ],
$e[ 'gd:where attr' ][ 'valueString' ],
$e[ 'content' ] );
}
If you want to do it really properly, you check for each key of $e ("startTime" and so on) first using isset() or array_key_exists().
