如何在 Mac OS X 中升级 PHP？

There is no built-in package manager. MacPorts doesn't recognize php as an installed package because it didn't install PHP itself.

You could still install it with MacPorts. sudo port install php52 (or whichever version you want) will install PHP.

It won't overwrite the Apple-supplied version. It'll install it under /opt/local. You can add /opt/local to the beginning of your $PATH, and use the MacPorts version in your Apache config.

Upgrading to Snow Leopard won't solve the your primary problem of keeping PHP up to date. Apple doesn't always keep the third party software that it bundles up to date with OS updates. And relying on Apple to get you the bug fix / security update you need is asking for trouble.

Additionally, I would recommend installing through MacPorts (and doing the config necessary to use it instead of Apple's PHP) rather than try to upgrade the Apple supplied PHP in place. Anything you do to /usr/bin risks being overwritten by some future Apple update.

You may want to check out Marc Liyanage's PHP package. It comes in a nice Mac OS X installer package that you can double-click. He keeps it pretty up to date.

Also, although upgrading to Snow Leopard won't help you do PHP updates in the future, it will probably give you a newer version of PHP. I'm running OS X 10.6.2 and it has PHP 5.3.0.

best way to upgrade is compile it from source

see this tutorial that may be helful for you

Option #1

As recommended here, this site provides a convenient, up-to-date one liner.

This doesn't overwrite the base version of PHP on your system, but instead installs it cleanly in /usr/local/php5.

Option #2

My preferred method is to just install via Homebrew.

Before I go on, I have the latest version (v5.0.15) of OS X Server (yes, horrible, I know...however, the web server seems to work A-OK). I searched high and low for days trying to update (or at least get Apache to point to) a new version of PHP. My mcrypt did not work, along with other extensions and I installed and reinstalled PHP countless times from http://php-osx.liip.ch/ and other tutorials until I finally noticed a tid-bit of information written in a comment in one of the many different .conf files OS X Server keeps which was that OS X Server loads it's own custom .conf file before it loads the Apache httpd.conf (located at /etc/apache2/httpd.conf). The server file is located:

/Library/Server/Web/Config/apache2/httpd_server_app.conf

When you open this file, you have to comment out this line like so:

#LoadModule php5_module libexec/apache2/libphp5.so

Then add in the correct path (which should already be installed if you have installed via the http://php-osx.liip.ch/ link):

LoadModule php5_module /usr/local/php5/libphp5.so

After this modification, my PHP finally loaded the correct PHP installation. That being said, if things go wonky, it may be because OS X is made to work off the native installation of PHP at the time of OS X installation. To revert, just undo the change above.

Anyway, hopefully this is helpful for anyone else spending countless hours on this.

I use this: https://github.com/Homebrew/homebrew-php

The command is:

$ xcode-select --install


$ brew tap homebrew/dupes
$ brew tap homebrew/versions
$ brew tap homebrew/homebrew-php


$ brew options php56
$ brew install php56

Then config in your .bash_profile or .bashrc

# Homebrew PHP CLI
export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"

to upgrade php7 to latest stable version brew upgrade php7 or for php5.X to latest stable version

brew upgrade php56

use brew list to check installed version

Saving on keystrokes, this worked on MacOS Sierra:

$ brew install homebrew/php/php71


$ /usr/local/opt/php71/bin/php -v
PHP 7.1.4 (cli) (built: Apr 14 2017 15:02:16) ( NTS )

Check your current php version in terminal with the following command,

$ php -v

You see current php version in terminal, and next command run in terminal if you want to upgrade your php version with php concat with version liked as,

$ brew install homebrew/php/php71

Please restart terminal if you finished php version upgrade installed and run the command.

$ php -v

Now you see the current php version in terminal....thank

I think one simple way to do it, is:

1 - Check you where is your current PHP:

$ which php
$ /usr/local/bin/php

You see? Usually, our commands that we run is a link in /usr/local/bin so...

2 - Unlink this current link of PHP

unlink /usr/local/bin/php

If you prefere, before unlink it, check the path and then remove php files (do ls -al /usr/local/bin | grep php and then rm -rf into desired path)

3 - Install PHP 7.1

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.1

4 - Create new link (using php 7.1 bin that you have installed)

ln /usr/local/php5-7.1.9-20170914-100859/bin/php /usr/local/bin/php

Like I said, its a simple way I think.

Use this Command:

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.0

You can use curl to update php version.

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.3

Last Step:

export PATH=/usr/local/php5/bin:$PATH

Check the upgraded version

php -v
