Php+Apache+Mysql download
php download: http://www.php.net After entering the php official website, click download to enter the following interface. Different versions are shown above. I chose version php5.6.19, which is more stable. If there is no version requirement, it is recommended to use this version. Develop PHP in a Windows environment, so continue to click Windows downloads in the picture to download the compressed package.
In the interface you enter, you can see that there are mainly VC11 X64 Thread Safe, VC11 X64 None Thread Safe and other versions. I chose the VC11 X64 Thread Safe thread-safe ZIP compressed package.
After downloading, unzip it directly to the directory you want to place it. Remember that it must be in the same directory as the next Apache installation package. Open the folder and you can see the files. ext stores all the dynamic link libraries that will be used later. Since the file (.dll) is a compressed package, we need to set it manually; there is no php.ini file in the original folder, so we need to copy and rename the php.ini-development file in the package, because we need php.ini to Carry out the php initialization we set.
Apache download: http://www.apachehaus.com/cgi-bin/download.plx This link goes directly to the download interface. Apache can directly download the latest version. For compatibility reasons, it is recommended to choose the VC9 version. The specific difference is on the web page. If there is an explanation, I won’t go into details here.
Click Download in the red border to download and install the package, and then follow the prompts to install. Remember to install it in the same directory as the php decompression package
Next, you need to configure and install the main service of Apache. With it, Apache can be started:
Open the CMD window and enter : "D:studytoolsApachebinhttpd.exe" -k install -n apache where D:studytoolsApachebinhttpd.exe is my own path, you need to change it according to your own path.
Remember to include quotation marks. The meaning of this command is to install the apache service, name the service as apache (you can also change it to something else), and press Enter.
The service is installed. After completion, it will be automatically tested. If there is a problem, the window will prompt an error. At this time, please troubleshoot based on the error.
Among them, Errors reported here must be corrected before the service can be started. This means that if there is an error message after this sentence, it means that the service installation failed and the error needs to be corrected first. If not, success.
There are too many steps to download and install Mysql. The online tutorials are very detailed, so I will omit them here...
However, the editor has shared a few articles for everyone for your reference:
mysql 5.7.12 winx64 installation and configuration method graphic tutorial
mysql 5.7.13 installation and configuration method graphic tutorial (linux)
mysql 5.7.13 winx64 installation and configuration method graphic tutorial
Wonderful topic sharing: installation tutorials for different versions of mysql
Now let’s build the environment of the three:
1. In order to enable PHP to connect to Mysql and Apache to parse PHP, we need to make some changes to PHP and Apache.
(1) Copy the php.ini-development file and change it to php.ini and put it in the original folder
(2) Open the php.ini file and find ;extension=php_mysql.dll ;extension=php_mysqli.dllRemove the ";" in front as shown below
After removing the preceding semicolon, you can then connect to the database using mysql or mysqli. When you want to use other methods such as PDO to connect to the database in the future, you can follow the tutorial to cancel the following PDO account bans. Then find "extension_dir=" and fill in the path of your own dynamic link library folder, that is, /php/ext. For example, the ext package path under my php is D:studytoolsphpext, so set it to the red box as shown below. In this way, we have given the path of the dynamic link library included in php. It is recommended that it is best to add the path of ext to the Path in the computer's environment variable.
After this, there will be no problem between php and the database
Next, solve the problem of Apache parsing PHP
1. Open the httpd.conf file in the conf folder under the Apache installation package, find Define SRVROOT " " and write the path of Apache in the title, then add the following code to save it
LoadModule php5_module "E:/wamp/php-5.6/php5apache2_4.dll"
PHPINIDir "E:/wamp/php-5.6/"
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
Whether the test was successful
Finally, you can start writing your own php file in the htdocs folder under Apache. You can write a test.php file with the content:
<?php phpinof(); ?>
Save, open ApacheMonitor.exe in the bin file under Apache, click start, and then enter localhost/test.php on the website. If the environment is successfully installed, the following interface will appear. There will be PHP information on the interface. If MySQL is connected, MySQL related information will also appear later.
The above is the entire content of this article. I hope it will be helpful to everyone’s study. I also hope that everyone will support Script Home.

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。

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。

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)”。
