Introduction

This package is designed to allow the creation of image placeholders with minimal fuss by providing data URIs to be substituted into an img or source's src or srcset attributes.

The aim is to create a placeholder that meets the following criteria:

• Behaves exactly like a genuine image when styled and resized.
• Can be used when developing offline.
• Does not require additional JavaScript introduced into the page.
• Keeps data URI size to a minimum.

The only option right now is to use SVG for this.

Installation

composer require dmnc/ssip

Usage

Placeholders are immutable and created directly through their constructor.

use Dmnc\Ssip\Placeholder;

$placeholder = new Placeholder(100, 50, "#aaa");

echo '<img src="' . $placeholder . '" alt="Stay accessible out there" />';

Support

Currently tested on:

• Chrome 80

Alternatives

If you require more feature rich placeholders, and are able to add JavaScript into your page, I suggest the fantastic Holder.js.
