1. Let’s first talk about the principle of automatic deployment. Generally, when we push the code, we can automatically request the url set in the webhook to complete a request and response. So as long as the content of the PHP file requested by the url address we set is to execute the command line git push command, we can push the code to the remote end once every time locally, and the server will automatically git pull to pull the latest branch.
2. Then what we need to set are two places:
①The webhook settings of the git project:
Generally, on the platform where we host the code, there will be one in the project settings. There is usually only one piece of content in the webhook settings, which is the url setting. Here I set http://www.xxxxx.com/webhook.php
(obviously, I am in the root directory of the website Throwing a webhook.php file, then every time I push code to the remote end, the webhook.php file of my website will be accessed)
②The hook file on the server side (where the code runs) ( webhook.php) settings:
$command = 'cd 代码位置'; $output = shell_exec($command); $command = 'git pull'; $output = shell_exec($command); print $output;
Here are two simple sentences. First cd command to enter the corresponding directory, and then execute the git pull command
Mainly for the shell_exec() function Use, this is a function for PHP to execute the command line. Students can introduce it in detail on Baidu.
What I want to note here is that when I executed the shell_exec() command before, the server would become unresponsive and stuck, so I used the
$output = shell_exec('ls'); print_r($output);
command to test, and found that it also timed out, which was very strange, so I kept putting it aside and couldn't figure out what was going on. After all, it was only three or five lines of code, and I didn't know why it kept requesting timeout. . Two months later, I wondered if it was a problem with the string encoding of the original print? So there are the following lines of code:
$encode = mb_detect_encoding($output, array('ASCII','GB2312','GBK','UTF-8')); $trans = iconv( $encode, "UTF-8",$output); print $trans;
Then it can be executed. . . I can't remember why shell_exec() kept timing out before. Friends who encountered it again can try not to print the return content, or encode the printed content. However, I believe that there are still a small number of friends who encounter this disgusting problem.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。
