Thinkphp has a built-in template engine that is comparable to smarty, which brings us great convenience. The same goes for calling functions. You can call the functions you need just like smarty, and the official has built-in some commonly used functions for everyone to call.
For example, the string interception function we are talking about today can be written like this in the thinkphp template engine: {$vo.title|msubstr=0,5,'utf-8′,false} As for {$vo.title}, everyone It’s definitely no stranger. Let’s talk about the following function msubstr. What it means is to intercept the string $vo.title, starting from 0 characters and intercepting 5 characters. UTF-8 encoding is used. By default, ellipses are not displayed after interception. If you want to display ellipses, just change false to true.
Function explanation:
msubstr($str, $start=0, $length, $charset=”utf-8″, $suffix=true)
$str: the string to be intercepted
$start=0: start Position, starting from 0 by default
$length: intercepted length
$charset=”utf-8″: character encoding, default UTF-8
$suffix=true: whether to display an ellipsis after the intercepted character, default true display, false Not displayed
Note: If it cannot be called normally, it means that you have not loaded the function library. You can use Load('extend'); to load the function and put it in the action~!
Note: The method of extending the function library cannot be used directly. It needs to be loaded or copied into the project function library before it can be used.
To load the extended function library, use:
Load('extend');
After loading the extended function library, you can call all functions in it.
function index(){
Load('extend'); //here here!
if($_POST['password']!=$_POST['repassword']){
$this->error('Two passwords are inconsistent');
$user=D('user');
if ($vo=$user->create()){
......
}
After trial: The official msubstr function seems to be unable to add an ellipse anyway. I found a modification method on the official website forum. The test can be used normally~! Modify the msubstr function of the Commonextend.php file to the following code:
Php code
/**
+-------------------------------------------------- ----------
* String interception, supports Chinese and other encodings
+------------------------ ----------------------------------
* @static
* @access public
+-- -------------------------------------------------- ------
* @param string $str The string that needs to be converted
* @param string $start Starting position
* @param string $length Interception length
* @param string $charset Encoding format
* @param string $suffix truncate display characters
+---------------------------------------- --------------------------
* @return string
+-------------------------- ----------------------------------------
*/
function msubstr($str, $start=0, $length, $charset="utf -8", $suffix=true)
{
if(function_exists("mb_substr")){
if($suffix)
return mb_substr($str, $start, $length, $charset)." ... ";
Else
Return MB_SUBSTR ($ Str, $ Start, $ Length, $ Charset); return iconv_substr($str,$start,$length,$charset)."...";
. ['utf-8'] = "/[x01-x7f]|[xc2-xdf][x80-xbf]|[xe0-xef][x80-xbf]{2}|[xf0-xff][x80-xbf ]{3}/";
$re['gb2312'] = "/[x01-x7f]|[xb0-xf7][xa0-xfe]/";
$re['gbk'] = "/ [x01-x7f]|[x81-xfe][x40-xfe]/";
$re['big5'] = "/[x01-x7f]|[x81-xfe]([x40-x7e]|xa1-xfe])/";
preg_match_all($re[$charset], $str, $match);
$slice = join("",array_slice($match[0], $start, $length));
if($suffix) return $slice."…";
return $slice;
}

thinkphp是国产框架。ThinkPHP是一个快速、兼容而且简单的轻量级国产PHP开发框架,是为了简化企业级应用开发和敏捷WEB应用开发而诞生的。ThinkPHP从诞生以来一直秉承简洁实用的设计原则,在保持出色的性能和至简的代码的同时,也注重易用性。

thinkphp基于的mvc分别是指:1、m是model的缩写,表示模型,用于数据处理;2、v是view的缩写,表示视图,由View类和模板文件组成;3、c是controller的缩写,表示控制器,用于逻辑处理。mvc设计模式是一种编程思想,是一种将应用程序的逻辑层和表现层进行分离的方法。

thinkphp查询库是否存在的方法:1、打开相应的tp文件;2、通过“ $isTable=db()->query('SHOW TABLES LIKE '."'".$data['table_name']."'");if($isTable){...}else{...}”方式验证表是否存在即可。

thinkphp扩展有:1、think-migration,是一种数据库迁移工具;2、think-orm,是一种ORM类库扩展;3、think-oracle,是一种Oracle驱动扩展;4、think-mongo,一种MongoDb扩展;5、think-soar,一种SQL语句优化扩展;6、porter,一种数据库管理工具;7、tp-jwt-auth,一个jwt身份验证扩展包。

在thinkphp3.2中,可以利用define关闭调试模式,该标签用于变量和常量的定义,将入口文件中定义调试模式设为FALSE即可,语法为“define('APP_DEBUG', false);”;开启调试模式将参数值设置为true即可。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
