When comparing PHP vs Inkscape, the Slant community recommends Inkscape for most people. In the question“What are the best web design tools?” Inkscape is ranked 8th while PHP is ranked 25th. The most important reason people chose Inkscape is:
Inkscape is GPL-licensed and maintains public repositories.
Ranked in these QuestionsQuestion Ranking
Pro One of the most common languages
According to the 2015 Stack Overflow Developer Survey (26,086 people surveyed), PHP was the 5th most popular/used language at 29.7%.
Pro Lots of tutorials online
Pro Used by most common CMS platforms
Many clients are looking for an easy-to-update web site that's flexible and free. Drupal and Wordpress fill those needs very well.
Pro Most prominent language for web applications
Part of the de facto standard web application stack.
Pro Great third-party package manager
PHP standard library is somewhat subpar, but if you need plugins, language features, composer has them all( you can even puzzle together a custom framework from composer).
Since 7.x was released, PHP has become a pretty fast language.
Pro Lots of PHP frameworks available which help with development
PHP people love frameworks, and with frameworks such as Laravel, you can build a web app or API really fast (Facades, ORMs, scaffolding etc.)
Pro Great documentation
Pro Free and open source
Inkscape is GPL-licensed and maintains public repositories.
Pro Opens lots of file types
Inkscape supports many common formats for import (including SVG, Photoshop and Illustrator) and its plugin architecture allows more to be added.
Pro Export to different file types
You can export and save your files for example as a "normal" svg, png, jpg, bmp etc. file.
Pre-built binaries are available for Windows, Mac and Linux. Inkscape can be built from source on additional platforms.
Pro Integrates well into a X11-System
Its uses the X11 icon theme and desktop theme(GTK).
Pro Dark Theme Support
The new 1.0 beta 2 version finally got support for dark theme which normally is only available for commercial software like Affinity Serif, Adobe Illustrator.
Pro Measurement Tool
This tool is extremely handy and I was not able to find it in any other vector graphics programs out there.
Pro Live Path Effects
Extremely powerful menu that offers more than 30 powerful Live Path Effects to apply to your paths vastly enhancing the application functionality.
Pro It can do anything
A very powerful software that can do pretty match anything!
Pro Interface is available in 29 languages
Basque, British English, Brazilian, Portuguese, Catalan, Croatian, Czech, Dutch, Finnish, French, German, Greek, Hindi, Hungarian, Icelandic, Indonesian, Italian, Korean, Latvian, Norwegian (Bokmål), Polish, Romanian, Russian, Slovak, Spanish, Swedish, Turkish, Ukrainian, Urdu, Swedish.
Pro Guides, Grids, and Canvas Rotation
Extremely handy features when building complex graphics using Inkscape.
Pro The new version 1.1 is looks and feels fantastic
Inskape got UI update: new dockable dialogs.
Pro It's really easy and fun
You can edit and create vector graphics with Inkscape.
Con Poorly designed language
Despite its widespread use, PHP is generally looked upon poorly from a design point of view. The consistency of function names and function argument order, lazily and borderline non-functional implementation of object oriented programming, can only receive requests via POST methods, slow version adoption (the PHP you learn right now may not work on every webserver you'll work on), and a focus on "hacking things together" rather than "doing it right". These are all very common complaints when it comes to working with PHP. While not a bad language to learn, PHP is not at all a good language to learn first, as it will probably teach bad habits.
Con Immense catalog of insecure frameworks
The most serious security problems in websites on the web today are almost universally found in popular PHP frameworks, CMS platforms, libraries and code samples, almost all stemming from poor language design, bad tutorials and awful resources.
Con After python, probably one of the worst languages ever
Con Poorly designed language, awful syntax & luckily on the decline
Nobody in their right mind is using PHP for new software, if you decide to learn it as your first language you'll be stuck working in teams with old developers who have had no interest in the computer programming field since they landed their first job while maintaining some 2000 era archaic website codebase.
Con Most tutorials are out of date
A lot of very bad tutorials are still widely circulated among beginners, and these tutorials teach very poor programming practices.
Con Most resources are poorly-written
Few resources exemplify the "correct" or secure use of features.
Con Interpreter being too permissive
If you forget the dollar sign, the variable name will be converted to a string.
Con Very slow startup on some systems
Depending on factors like how many fonts you have installed, Inkscape can take upwards of 30 seconds to launch.
Con Based on the GTK widget toolkit
Software is based on GTK, so it might not integrate well in non-GTK environments. It also requires many dependencies on those non-GTK desktops. It also adds dependencies to GTK-environments since it is written in C++ which requires the gtkmm wrapper/interface.
Con Uses its own SVG-format by default
Inkscape might use SVG as its default format, however this SVG's contains some additional SodiPodi/Inkscape additions that can be troublesome if you want to import the SVG into some other application.
Con Mac version does not look as polished as its versions for Windows/Linux version for the 0.92.x version
It seems that Inkscape 1.0 beta 2 for Mac got some needed attention and it looks a lot better with dark theme support. native DMG installer and they got rid of X11 which is great.
Con Crashes very often
Inkscape encountered an internal error and will close now - is one of its standard messages.
Application is often buggy so it happens from time to time that the popup / right-click menu won't close and stays open. It crashes also sometimes randomly. This makes it almost unusable for productive / business use.
Con Limited work with ICC CMYK color scheme
Support for ICC color profiles only in SVG files.
Con Incompatible with previous versions
Sometimes backward compatibility breaks. For example, pre 0.92 SVGs are incompatible with later releases (due different default resolutions).
Con 1.0 is sluggish
Inkscape 1.0 uses GTK 3 which is sluggish and slow for low spec systems( eg. ARM, Celeron, Pentium, Core-i3, Ryzen 3 or Athlon ) compared to previous versions.
Con Since 0.91 the gradient editor is gone
It is now only possible to edit a gradient on screen. but you can't set a stop to a specific percentage anymore.
Con Y-axis inverted
0,0 coordinates begin in lower left corner, not upper left corner as SVG standards define in Inkscape 0.92.x.
It seems this is now fixed in the 1.0 beta 2 version of the program.
Con No support for large printing machine system
No support for large printing machine environment, except exporting the resulting artwork to PDF.
Con Under GNU GPL
It is released under GNU GPL which one of the restricted open source license.
