Question

我有一个SQL查询和PHP代码，显示包含时间（来自数据库的TIMESTAMP＆＃39; d）的帖子提要，PHP代码将该时间转换为帖子发布的持续时间。

但它已经回响了45年前＃34; （我知道Unix时间是在45年前 - 1970年开始的）

示例 - 现在的时间是2015年8月28日 - 美国东部时间晚上9:24，我在美国东部时间晚上9:59看到该帖子，它应该说＆＃34; 35分钟前＆＃34;

这是代码

<?php
$servername = "localhost";
$username = "xxxxxx";
$password = "xxxxxx";
$dbname = "xxxxxxx";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("<center><img src='http://s1.postimg.org/gflrr630f/unnamed.png' width='200' height='200'><br><br><font face='helveticaneue-medium' size='5' color='white'>There seems to be an error establishing a connection to the CDN.<br><br>Please contact an administrator <b>immediately</b>!</font></center>");
} 

$sql = "SELECT * FROM posts WHERE bp='0' ORDER BY id DESC LIMIT 50";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
$post_time = $row["time"];
$time = strtotime('$post_time');
        echo "<div class='entire' style='margin: auto;width: 98%;background-color: white;padding-top: 7px;box-shadow: 0px 2px 5px 0px rgba(0,0,0,0.50);border-radius:5px;'> <span style='margin-left:10px;'><div style='margin-left:10px;'><img src='" . $row["pro_pic"].

    }
} else {
    echo "0 results";
}
$conn->close();
?>
<br>
<?php


function humanTiming ($time) 
{
date_default_timezone_set('America/New_York');

    $time = time() - $time; // to get the time since that moment

    $tokens = array (
        31536000 => 'year',
        2592000 => 'month',
        604800 => 'week',
        86400 => 'day',
        3600 => 'hour',
        60 => 'minute',
        1 => 'second'
    );

    foreach ($tokens as $unit => $text) {
        if ($time < $unit) continue;
        $numberOfUnits = floor($time / $unit);
        return $numberOfUnits.' '.$text.(($numberOfUnits>1)?'s':'');

    }

}
?>

Answer 1

PHP变量不以单引号进行插值。所以：

$time = strtotime('$post_time');

表示'$post_time'是一个文字字符串。只需删除引号，并假设$post_time包含有效的日期格式，这将有效。

PHP时间不正确 - 与45年前相呼应
