我聊天,消息的印刷或多或少是这样的:
Jhon:嘿!Jhon:好吗?
史密斯:是的,我很好。感谢。Jhon:太好了!
打印我有代码:
array(4) {
[0]=>
array(3) {
["from"]=>
string(4) "Jhon"
["to"]=>
string(5) "Smith"
["msg"]=>
string(4) "Hey!"
}
[1]=>
array(3) {
["from"]=>
string(4) "Jhon"
["to"]=>
string(5) "Smith"
["msg"]=>
string(5) "Fine?"
}
[2]=>
array(3) {
["from"]=>
string(5) "Smith"
["to"]=>
string(4) "Jhon"
["msg"]=>
string(23) "Yeah, I'm fine. Thanks."
}
[3]=>
array(3) {
["from"]=>
string(4) "Jhon"
["to"]=>
string(5) "Smith"
["msg"]=>
string(12) "That's nice!"
}
}
我想要显示如下消息:
Jhon:嘿!精细?
史密斯:是的,我很好。感谢。Jhon:太好了!
谢谢你,对不起我的英语。

一个让你入门的小例子:
<?php
$messages = array(
array(
"From" => "A",
"To" => "B",
"Msg" => "A first message"
),
array(
"From" => "A",
"To" => "B",
"Msg" => "A second message"
),
array(
"From" => "B",
"To" => "A",
"Msg" => "B first message"
)
);
$previousSender = null;
foreach($messages as $message) {
if($previousSender == null || $previousSender != $message["From"])
printf("%s: %s", $message["From"], $message["Msg"]);
else
printf("%s", $message["Msg"]);
$previousSender = $message["From"];
}
?>
