PHP Illegal offset type
提问by VACIndustries
Warning: Illegal offset type in /email_HANDLER.php on line 85
$final_message = str_replace($from, $to, $final_message);
preg_match_all('/<img[^>]+>/i',$final_message, $result);
$img = array();
foreach($result as $img_tag)
{
preg_match_all("/(alt|title|src)=('[^']*')/i",(string)$img_tag, $img[$img_tag]); //LINE 85
}
Anyone? I'm about to tear my hair out over this...
任何人？我正要为此撕掉我的头发......
here is my var_dump of $img_tag
这是我的 $img_tag 的 var_dump
array(1) {
[0]=>
string(97) "<img alt='' src='http://pete1.netsos.com/site/files/newsletter/banner.jpg' align='' border='0px'>"

Assuming $img_tagis an object of some type, rather than a proper string, cast $img_tagto a string inside the []
假设$img_tag是某种类型的对象，而不是正确的字符串，$img_tag转换为[]
preg_match_all("/(alt|title|src)=('[^']*')/i",(string)$img_tag, $img[(string)$img_tag]);
//------------------------------------------------------------------^^^^^^^^^
Some object types, notably SimpleXMLElementfor example, will return a string representation to print/echovia the magic method __toString(), but cannot stand in as regular strings. Attempts to use them as array keys will yield the illegal offset typeerror unless you cast them to proper strings via (string)$obj.
一些对象类型，特别SimpleXMLElement是例如，将print/echo通过魔法方法__toString()返回一个字符串表示，但不能作为常规字符串。尝试将它们用作数组键会产生illegal offset type错误，除非您通过(string)$obj.

See first comment on this PHP bug report:
请参阅有关此 PHP 错误报告的第一条评论：
You cannot use arrays or objects as keys. Doing so will result in a warning: Illegal offset type. Check your code.
不能使用数组或对象作为键。这样做会导致警告：非法偏移类型。检查您的代码。
Ensure that $img_tagis of the appropriate variable type.
确保它$img_tag是适当的变量类型。

$resultis 2-dimentional array.So, $img_tagshould be an array.
$result是二维$img_tag数组。所以，应该是数组。
But only integers and strings may be used as offset
但只能使用整数和字符串作为偏移量

foreach( $result[0] as $img_tag)
it works
有用
