Modify the Mac default PHP running environment and configure global Composer for MAMP

When global Composer is not configured, if you run the Composer command in a directory where Composer is not installed, such as: create-project, the system will return:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px>
Could not open input file: composer.phar
</codemicrosoft>

Okay, let’s find out why and take a look at the Composer documentation It is said that Composer should be moved to the /usr/local/bin directory:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px>
mv composer.phar /usr/local/bin/composer
</codemicrosoft>

Run the Composer command again, it is still the same. Let’s look through the Composer documentation again. All Composer commands have a PHP, such as:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px>
php composer.phar update
</codemicrosoft>

Composer dependency As for PHP, well, at least it's not a problem with Composer. It may be a problem with PHP. We all know that Mac comes with a PHP preset in the system when it leaves the factory, and we are using MAMP's PHP. Maybe the problem lies here. Run it in Terminal:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px>
which php
/usr/bin/php
</codemicrosoft>

The problem is confirmed, it is a problem with PHP. To be precise, it is a problem with PHP environment configuration. Let’s configure the environment:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px><span>sudo</span> nano ~/.bash_profile
<span># 添加一行。注意 PHP5.4.10 修改成你正在运行的 PHP 版本目录名称</span><span>export</span> PATH=<span>"/Applications/MAMP/bin/php/php5.4.10/bin:<span>$PATH</span>"</span><span># 保存，退出</span><span># 运行一下 .bash_profile 文件</span>
. .bash_profile
<span># 确认当前正在运行哪个 PHP</span>
which php
/Applications/MAMP/bin/php/php5.<span>4.10</span>/bin/php
</codemicrosoft>

Okay, so far, the PHP running environment has been configured. Come on Reinstall Composer:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px><span>cd</span> /usr/local/bin
curl <span>-s</span>S https://getcomposer.org/installer | php

Composer successfully installed to: /usr/local/bin/composer.phar
Use it: php composer.phar

<span># 修改一下 composer.phar 文件的权限</span><span>sudo</span> chmod a+x composer.phar
</codemicrosoft>

Oh, let’s run the Composer command:

<codemicrosoft yahei color:rgb white-space:pre-wrap padding:0px border:0px margin-top:-1.2em display:block background:0px><span>cd</span> /my/project/path
<span># 注意此时 composer.phar 命令前面已经不需要加 php 了</span>
composer.phar create-project
composer.phar self-update
composer.phar install
composer.phar update
</codemicrosoft>

Done! At this time, it's time to eat, and it's time to go to sleep.

The above has introduced how to modify the default PHP running environment on Mac and configure global Composer for MAMP, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
