mongo php库安装错误

我有mongodb版本3.2.3和php mongo驱动程序版本1.6.12。我正在尝试使用composer进行安装

$ composer require "mongodb/mongodb=^1.0.0"

得到了这个错误：

Your version of PHP, 5.4.16, is affected by CVE-2013-6420 and cannot safely perform certificate validation, we strongly suggest you upgrade.
./composer.json has been created
Loading composer repositories with package information

问题1

- mongodb/mongodb 1.0.1 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.

- mongodb/mongodb 1.0.0 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.

需要帮助来解决这个问题。我是否安装了错误版本的库？请大家分享我可以安装mongo php库的链接或命令

您需要更新您的php版本。转到PHP7

对于以下PHP5.6 plz，请尝试以下方法：

$ pecl install mongodb

$ echo "extension=mongodb.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`

或者根据您的php版本下载mongodb.so文件，并将其粘贴到php/ext文件夹中

$pecl安装mongodb

。在php.ini中添加

extension=mongodb.so

。如果出现错误：

sasl.h notfound

，您需要安装cyrus sasl-devel，如果php pear中出现错误，由于PHP5.6版本，您应该卸载php pear并安装php56w pear

$ pecl install mongodb

$ echo "extension=mongodb.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
