我试图在我的数据库中存储用户的电话号码,但MySQL会自动删除前0,信息来自html表单.
例如:当有人输入电话号码时0123456789,mysql会存储该值123456789.
有谁知道如何使这项工作,并包括0在数据库中？
我在下面的Wordpress中使用此功能:
function wpstudio_doctype() {
$content = '<!DOCTYPE html>' . "\n";
$content .= '<html ' . language_attributes() . '>';
echo apply_filters( 'wpstudio_doctype', $content );
}
问题是该函数显示$content在<!DOCTYPE html>标记上方,而不是在标记内添加字符串HTML.
我在这做错了什么？
我的代码PHP有问题,我的数据库是Mongodb:
我收到此错误:
警告:date()期望参数2很长,
我的代码是:
<?php echo date('g:i a, F j', $comment['posted_at']); ?>
我试图name从这块JSON中获取值:

我正在创建一个函数来检查哪个日期在一个充满日期的数据库表中小于当前日期.和过去一样.
我有3个日期来测试函数,以及它们后面的输出:
上个月的
日期:28-04-2015 16:32:00
日期尚未到来:11-06-2015 13:12:00
日期:上一周:04-05-2015 09:45:00
$dateNow = date('d-m-Y H:i:s'); //Current
$deadlineDate = "28-04-2015 16:33:18";
if($deadlineDate < $dateNow){ //If date from last month is smaller then the current date
echo '<tr class="overdue">'; //Overdue class gives that tr an red background color to mark it
echo '<td>'.$deadlineDate.' is smaller then '.$dateNow.'</td>';
}else{
echo '<tr>';
echo '<td>'.$deadlineDate.' is bigger dan '.$dateNow.'</td>';
}
</tr>
输出:
28-04-2015 16:32:00 返回更大
11-06-2015 13:12:00 返回较小 …
其他一切都应该没问题,但我仍然有问题显示else功能.理论上我相信一切都应该有效.我查看了所有语法,一切看起来都很好,一切都已正确关闭.我想要做的是,如果$_GET['cat'] == 1, 2, or 3(这就是为什么我使它成为一个数组)是有效的,那么我希望能够拉出那个特定的类别,如果没有那么我希望它能一起显示所有的类别.很像WordPress的功能.
<?php
include('config.inc.php');
// security check to make sure it's not grabbing anything extra that's not there
$get_cat_id = mysqli_query($mysql_conn, "SELECT `id` FROM `categories`");
$cat_array = array();
while($row = mysql_fetch_assoc($get_cat_id)) {
$cat_array[] = $row['id'];
}
echo $cat_array[];
// checks to see if it's calling for a specific category
if(isset($_GET['cat']) && ($_GET['cat'] == $cat_array)) {
$fetch_post_content = mysqli_query($mysql_conn, "SELECT * FROM `posts` WHERE `category_id` = '".$_GET['cat']."' ORDER BY `id` DESC");
$fetch_category_content = mysqli_query($mysql_conn, "SELECT …我有一个简单的Vars.php页面:
<?php
//Vars.php
$WeekOfDateSelected = date('l, m/d/Y', strtotime($MonthYear));
$NextSundayOfDateSelected = date('l, m/d/Y', strtotime('this Sunday', strtotime($WeekOfDateSelected)));
?>
我有另一个包含Vars.php的PHP并构建一个表:
<html>
<?php
//AnalyticsTest.php
include($_SERVER['DOCUMENT_ROOT']."/~/~/~/~/~/Vars.php");
function WeekTable() {
echo "<table id=\"a\">
<tr>
<th style=\"text-align: center;\"><a href=\"#\">< previous week</a></th>
<th colspan=\"4\" style=\"text-align: center;\"><h2>Week of ";
echo $WeekOfDateSelected;
echo " - ";
echo $NextSundayOfDateSelected;
echo "</th>
<th style=\"text-align: center;\"><a href=\"#\">next week ></a></th>
</tr>
</table>";
}
?>
</html>
基本上,当我WeekTable()正确调用所有输出时,除了PHP变量$WeekOfDateSelected和$NextSundayOfDateSelected输出空白.
我正在尝试按字母顺序对字符串进行排序.我以为我可以将一个字符串分解为一个数组并对其进行排序,但是回声没有返回任何内容.
$schools = "high*low*other*";
$schools = explode("*", $schools);
$schools = sort($schools);
echo $schools[0];
echo mydate(strtotime('1 am first day of this month'));
以上是结果2017-10-01 01:00:00,但我很难在凌晨0点做到.两者都24am, 24pm, 0pm, first second不起作用.
