我正在打印一个结构
$structure = imap_fetchstructure($imap, $email_number);
print_r($structure);
我需要查看数组内部并获取我的内联附件的[disposition]标签。
我正在尝试使用：
$inline_attachment = $structure[1]->disposition;
if($inline_attachment == inline){
echo "inline attachment found!!";
}
stdClass Object (
[type] => 1
[encoding] => 0
[ifsubtype] => 1
[subtype] => RELATED

[ifparameters] => 1
[parameters] => Array
(
[0] => stdClass Object
(
[attribute] => name
[value] => 1.jpg
)
)
)
)
)
实现这一目标的最佳方法是什么？另外，我如何正确理解如何移动并获取数组中的任何特定元素？
echo var_export($structure);

for($i = 0; $i < count($structure->parts); $i++) {
if($structure->parts[$i]->disposition == inline) {
foreach($structure->parts[$i]->dparameters as $object) {
$src_cid = $object->value;
}
}
}

使用递归函数，您可以遍历对象的$parts数组以检查ifdisposition == 1的值，并检索dparameters[0]->value值。
这应该足以让你入门：
function getDispositions($obj) {
// Check ifdisposition is 1
if (isset($obj->ifdisposition) && $obj->ifdisposition == 1) {
// Print the disposition
echo "Disposition: {$obj->disposition}\n";
// And print the first parameter's value
echo "Filename: {$obj->dparameters[0]->value}\n";
// You may need to loop here instead like
//foreach ($obj->dparameters as $p) {
// echo $p->value;
//}
}
// If this has a parts array
if (isset($obj->parts)) {
// Loop over each part and call the getDispositions()
// function recursively to act on each nested part
foreach ($obj->parts as $part) {
getDispositions($part);
}
}
}
// Call the function on your outer structure
getDispositions($structure);
这将打印：
Disposition: inline
Filename: 1.jpg
这是一个演示，添加一个额外的文件名，以便打印两个处置和文件名值：http://codepad.viper-7.com/1zuxfo
