Linux下编译、安装php

由 戏子无情 提交于 2020-02-04 05:44:55
一、apache环境下php的安装步骤如下： 【 注意：编译安装php前，应先安装好apache,因为编译php时要用到apache的路径 】 1. 在http://www.php.net/downloads.php下载php源代码，并存至/usr/local/src下 2. 切换至/usr/local/src下，解压php源码，并切换至解压后的php目录下 3. ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/httpd/bin/apxs --enable-mysqlnd 【配置时，可能会报错configure: error: xml2-config not found. Please check your libxml2 installation.--------解决方法： 需安装libxml2作为依赖(centos和ubuntu上安装libxml2的方式不太一样)】 4. make 5. make install 6. 配置http.conf,主要是整合php作为apache的模块出现（有时会自动帮我们配置好），在http.conf里加一句 AddType application/x-httpd-php .php 7. 复制php源码包中的 php.ini-development到指定目录（此处为：

How to use column names in PHP PDO without binding columns

由 故事扮演 提交于 2020-02-02 16:21:23
问题 Is there a method to directly use the name of the column when outputting data without binding columns when using php pdo and mySql, instead of using $row[‘columnName’] . Eg: My current method $sql = "select id, name, address, country from members where country = :country"; $stmt=$conn->prepare($sql); $stmt->execute(array(':country' => $country)); while( $row = $stmt->fetch() ) { //I can forgo the while loop. echo $row[‘name’]; //Can I use $name here? echo $row[‘address’]; echo $row[‘country’]

Using PDO with other classes

由 雨燕双飞 提交于 2020-02-02 14:37:51
问题 I have been forcing myself to get into more OOP. I have hated it all up in till now. When i am using some simple prepare statment in PDO within another class as a method it never works. I resolved it by doing the obvious: globalising the PDO object into the method. It works, and does what i want - but if i had many many methods from loads of different classes, adding "global $db;" as the first line to alllll the functions/methods it seems quite tedious. Is there a way of integrating PDO into
