Why Increase Your Spider web Server'south PHP Upload Size

Every PHP installation uses a set of variables or "directives" that govern its settings. These are the three settings that determine how PHP deals with file uploads (as far every bit size is concerned):

  1. memory_limit: This determines how much retentiveness your server can classify to each PHP script.
  2. post_max_size: This setting controls the maximum size of Mail service data that your server will permit and plays a role in WordPress file uploads.
  3. upload_max_filesize: The value that you lot set hither determines the file size limit for uploads to your website.

As we mentioned, WordPress is congenital on PHP. Therefore, all of these settings straight impact your website. If your PHP installation has a low memory limit, you'll run into problems uploading files and executing scripts on your site.

There's no ideal PHP retentiveness limit that suits every web server. However, since we're talking about a local evolution environment, you have full liberty over how many resources to allocate to your setup. Whereas virtually web hosts will cap your PHP retention limit (within reason), there's no forced cap with your local instance.

Some tutorials tell you to only increase the upload_max_filesize setting within your PHP configuration. However, that tin atomic number 82 to errors. The PHP documentation is articulate when information technology indicates that your post_max_size setting should take a college value than upload_max_filesize.

Likewise, memory_limit should have a college value than post_max_size. As long every bit your PHP settings attach to those guidelines, you lot should be gold.

How To Increment the Upload Size for Your Local MAMP Web Server (in 2 Steps)

For this tutorial, we'll evidence yous how to configure MAMP to increase its upload size on both Windows and macOS. Nosotros'll too use the MAMP control panel to ensure that you updated your server settings successfully.

Step 1: Alter Your php.ini File

Modifying your PHP settings in MAMP is piece of cake. To do and so, you'll need to edit your MAMP installation'due south php.ini file.

You can access that file in one of these two locations, depending on whether you're using Windows or macOS:

  1. Windows: C:/MAMP/conf/phpx.x.10/php.ini
  2. macOS: /Applications/MAMP/bin/php/phpx.x.x/conf/php.ini

If you navigate to the conf directory, you'll notice that it includes several folders for unlike PHP versions. By default, your MAMP installation should utilise the latest PHP version, and you'll want to access the binder that corresponds to it.

Next, you can return to the conf directory and access the folder that correlates to that version. Inside, you'll discover a solitary php.ini file. Get ahead and open it using your favorite text editor, and you'll see something like this:

As we explained in the last department, you need to look for the following three directives:

  1. memory_limit
  2. post_max_size
  3. upload_max_filesize

We recommend setting a memory limit of 128 or 256 MB. Here'southward what that value looks like in our php.ini file:

To locate that directive, utilize your text editor's search functionality and modify the value afterwards the = sign.

Notice that the number is followed past a single "M" instead of an "MB". Both 128 and 256 MB give your WordPress installation more than enough resources to execute whatever scripts or upload the files that you'll need to use. You lot can too get higher if your computer has the resources for it, which shouldn't be a problem with modern devices.

At present repeat the same procedure for post_max_size and upload_max_filesize, using a higher value for the former. In most cases, y'all don't need to go college than 10 to 20 MB for either setting. After all, it's rare that you'll find yourself in a situation where you need to upload files of that size to a WordPress website.

In any example, you can ready any values that you want for either directive, as long as they follow the guidelines nosotros outlined earlier.

When you're done, save the changes to php.ini and close the file. And so y'all can return to the MAMP control console and click on Start Servers.

Footstep ii: Check Your phpInfo Folio

PHP can generate a page called phpInfo that enables you to bank check all your server configuration settings without having to navigate the php.ini file.

To access your MAMP phpInfo page, open the tool's control panel and click on the Open WebStart page push button:

In the screenshot above, you can see that we set our memory_limit value to 128 MB.

Go alee and employ your browser'southward search function to locate all 3 directives and check that phpInfo reflects their new values.
