fwrite

This question already has an answer here: Is fopen() limited by the filesystem? 4 answers I have a set of files that I want to concatenate (each represents a part from a multi-part download). Each splitted file is about 250MiB in size, and I have a variable number of them. My concatenation logic is straight-forward: if (is_resource($handle = fopen($output, 'xb')) === true) { foreach ($parts as $part) { if (is_resource($part = fopen($part, 'rb')) === true) { while (feof($part) !== true) { fwrite($handle, fread($part, 4096)); } fclose($part); } } fclose($handle); } It took me a while to trace it

前言 fread是吼东西 应某人要求（大概）科普一下 fread #include <iostream> #include <cstdlib> #include <cstring> #include <cstdio> #define fo(a,b,c) for (a=b; a<=c; a++) #define fd(a,b,c) for (a=b; a>=c; a--) using namespace std; char st[233]; char *Ch=st; int main() { fread(st,1,233,stdin); cout<<st<<endl; cout<<*Ch<<endl; } 可以用文件输入，也可以直接输并在最后加Ctrl+Z （下面的空行是因为读入了一个换行符） fread基本格式： fread(字符串,1,字符串大小,stdin); *Ch一开始指向的是st[0]，之后可以不断*++Ch来往后跳 快速读入 #include <iostream> #include <cstdlib> #include <cstring> #include <cstdio> #define fo(a,b,c) for (a=b; a<=c; a++) #define fd(a,b,c) for (a=b; a>=c; a--) using namespace std;

问题：fwrite(): send of 8192 bytes failed with errno=104 Connection reset by peer 问题描述 通过mysql + sphinx做的一个检索功能，之前一直没什么问题，最近检索时有部分检索失败，查看日志后报错为 fwrite(): send of 8192 bytes failed with errno=104 Connection reset by peer。 问题分析 查看代码部分，fwrite() 打开的资源为fsockopen()，通过fsockopen连接sphinx，将数据写入到sphinx服务端。 最终发现问题出在sphinx服务端，由于检索的数据太大，在请求sphinx服务端时，发送的包数据超过了sphinx可接受的最大值，导致以上问题。 解决方法 修改sphinx.conf中max_packet_size（最大允许的网络包大小）的设置值以解决问题。 来源： https://www.cnblogs.com/it-june/p/11782234.html

This means the output length is at most 123 chars. The 123 could be replaced by * , so that the length will be taken from the argument of printf instead of hard-coded. Note that this

Multiple strings are accepted as input from user & would contain '\n' and I am scanning it as: $data = explode("\n", $_GET['TxtareaInput']); Each string should be moved into the text file with new line character separation. This is the code I am using now and it separates each string with a '^M' character: foreach($data as $value){ fwrite($ourFileHandle, $value); } Is there anyway I can get each string followed by a carriage return? 回答1: Try this: $data = explode("\n", $_GET[

In my script I'll handle incoming text and generate response with params: ANSWER_TO_ID and RESPONSE_MESSAGE . The problem is that I'm sending response to incomming "ID_OF_MESSAGE" , but server which send me message to handle will set his message as delivered to me (It means I can send him response to that ID), after receiving http response 200. One of solution is to save message to database and make some cron which will be running each
