更新：
好的，我想通了，看起来 fread 有文件大小限制，将其更改为
file_get_contents('php://input')
，但现在让 SF 给出 java.net.SocketTimeoutException: Read timed out 错误，而 PHP 端什么也没有。我还添加了 set_time_limit(0); 到 PHP 脚本，如果我理解正确，只要它需要执行脚本。有什么想法吗？
顺便说一句：我最多可以处理 25 个（我已经测试过）但不能处理 100 个
我正在使用 Salesforce 将出站消息（通过 SOAP）发送到另一台服务器。服务器一次可以处理大约 8 条消息，但如果 SOAP 请求包含超过 8 条消息，则不会发回 ACK 文件。SF 可以在 1 个 SOAP 请求中发送多达 100 条出站消息，我认为这会导致 PHP 出现内存问题。如果我一个接一个地处理出站消息，它们都可以正常处理，我什至可以一次处理 8 个，没有任何问题。但是更大的套装不起作用。
SF中的错误：
org.xml.sax.SAXParseException: Premature end of file
查看 HTTP 错误日志，我看到传入的 SOAP 消息似乎正在被截断，这会引发 PHP 警告，说明：
DOMDocument::loadXML() ... Premature end of data in tag ...
PHP致命错误：
Call to a member function getAttribute() on a non-object
这让我相信 PHP 存在内存问题，并且由于它的大小而无法解析传入的消息。
我在想我可以设置：
ini_set('memory_limit', '64M'); // This has done nothing to fix the problem
但这会是正确的方法吗？有没有办法可以将其设置为随着传入的 SOAP 请求动态增加？
更新：添加一些代码
