这是循环获取内容的代码
<?php
$chat = file("members/cdn/1/chats/9188.txt");
foreach($chat as $line){
$name = strchr($line,":",true);
$message = explode(' ', substr(strchr($line,":"),1), 3);
if(some thing){
?>
<div>
<!-- here i want to skip the same dates -->
<?=$message[0];?>
</div>
<?php
}
?>
<div class="container">
<div class="arrow">
<div class="outer"></div>
<div class="inner"></div>
</div>
<div class="message-body">
<p><?=$message[2];?></p>
<p class="message_time"><?=date("g:i a", strtotime($message[1]));?></p>
</div>
</div>
<div class="spacer"></div>
<?php
}

只需记住您上次使用的日期,然后将其与doRequest(input).success {result in
print("success, with:", result)
}.failure {
print("fail :(")
}

试试这个:
$prevDate[] = array();
foreach($chat as $line){
$name = strchr($line,":",true);
$message = explode(' ', substr(strchr($line,":"),1), 3);
if(some thing){
?>
<div>
<!-- here i want to skip the same dates -->
<?php
if(!in_array($message[0],$prevDate)) { // check if date exist in array - means displayed previously or not
echo $message[0];
$prevDate = $message[0]; // store date in array so that next time you can check whether it has been already displayed or not
}
?>
</div>
<?php
}
?>
<div class="container">
<div class="arrow">
<div class="outer"></div>
<div class="inner"></div>
</div>
<div class="message-body">
<p><?=$message[2];?></p>
<p class="message_time"><?=date("g:i a", strtotime($message[1]));?></p>
</div>
</div>
<div class="spacer"></div>
<?php
}

首先,您可以使用列表分配将组件拆分为单独的变量:
list($user,$date,$time,$message) = explode(' ', substr(strchr($line,":"),1), 4);
然后您可以使用简单的比较来查看日期是否为新的:
if ($date != $last_date) {
$last_date = $date;
?><div><?=$date?></div><?php
}
您应该在循环之前声明$last_date
,但是您可以保留其值未定义。
