Server-side React with PHP – part 2

Sep 19th, 2013

Part 1 ended with todos. The first one was to couple the server-side generated code with the client-side React, so that any updates past the initial page load will be handled by React’s client JS, which is where React shines. Let’s see how you can do just that. PHP data fetch, gluing JS for v8 […]

 

Server-side React with PHP

Sep 13th, 2013

Problem: Build web UIs Solution: React Problem: UI built in JS is anti-SEO (assuming search engines are still noscript) and bad for perceived performance (blank page till JS arrives) Solution: React page to render the first view Problem: Can’t host node.js apps / I have tons of PHP code Solution: Use PHP then! This post […]

 

Installing v8js for PHP on a Mac

Sep 11th, 2013

Motivation? Run JS code inside PHP. Just… because I struggled for a while with this installation, so leaving a trail here for anyone looking. What you need to accomplish?

JavaScript-style object literals in PHP

Mar 20th, 2011

The object literal notation in JavaScript looks like: var fido = {name: "Fido", barks: true}; or var fido = {}; fido.name = "Fido"; fido.barks = true; From assoc arrays to objects In PHP you would call that an associative array. $fido = array( ‘name’ => "Fido", ‘barks’ => true ); And you can easily make […]

Automating HTTPWatch with PHP #2

Mar 7th, 2011

In part 1 I demonstrated how you can use PHP to script and automate HTTPWatch. And how you can get data back, either reading the API docs or using a quick HAR hack to get a lot of data in one go. Now I want to share a little class I wrote to make all […]

 

Automating HTTPWatch with PHP

Mar 5th, 2011

HTTPWatch is a nice tool to inspect HTTP traffic in easy and convenient way and it works in both IE and FF now. Drawback – windows-only and paid. But the free version is good enough for many tasks. HTTPWatch can be automated and scripted which is pretty cool for a number of monitoring-like tasks. Their […]

image diff

Nov 15th, 2008

Was having fun today with idiff.php – a PHP shell script to tell you if two images are visually different by comparing them pixel by pixel. If there’s a difference, the script creates a third image – black background with the different pixels in green. Only after writing the script I found that there’s an […]

Oct 26th, 2008

It’s that time of the year again. Time to cast my vote as part of the jury in Packt’s open-source awards, category “PHP CMS”. (for my last year’s rant, check the internet archive copy) How to judge a CMS? How to judge a CMS? Tough one. How do you judge any piece of software anyway? […]

My online footprint lately

Jul 23rd, 2008

This is a sort of a catch-up post for listing what I’ve been up to lately. YUI Blog just published my first article, I’m so proud. It’s about loading JavaScript in non-blocking fashion, because JavaScripts, they, you know, like, block downloads. Luckily, there’s an easy fix – DOM includes, which I’ve previously discussed, discussed and […]

 

www vs no-www and cookies

May 13th, 2008

One of Yahoo’s performance rules says: Use cookie-free domains for static components. This is good because the server has no use for cookie information when serving a JPEG or another static component, so all this cookie information creates network traffic for no reason. One of the implications of following the rule is related to the […]

Simultaneuos HTTP requests in PHP with cURL

Feb 19th, 2008

The basic idea of a Web 2.0-style “mashup” is that you consume data from several services, often from different providers and combine them in interesting ways. This means you often need to do more than one HTTP request to a service or services. In PHP if you use something like file_get_contents() this means all the […]

 

Fancy formatting

Dec 21st, 2007

Writing readable code means proper indentation. Usually you’d tab (or use 2 or 4 or 3 spaces) after every curly bracket. Something like this: if (true) { // indent if (false) { // another indent // and some more } } Same goes when you have a bigger hash/object sort of thing: var memememe = […]

 

Image fun with PHP – part 2

Nov 13th, 2007

This post is a demo of what the imagefilter() PHP function can do for you. The Original imagefilter() called with different filter constants Filter: IMG_FILTER_BRIGHTNESSCode to reproduce: <?php $image = imagecreatefrompng(‘nathalie.png’); imagefilter($image, IMG_FILTER_BRIGHTNESS, 5); imagepng($image, ’img_filter_brightness_5.png’); imagedestroy($image); ?> Filter: IMG_FILTER_BRIGHTNESSCode to reproduce: <?php $image = imagecreatefrompng(‘nathalie.png’); imagefilter($image, IMG_FILTER_BRIGHTNESS, 50); imagepng($image, ’img_filter_brightness_50.png’); imagedestroy($image); ?> Filter: IMG_FILTER_BRIGHTNESSCode to reproduce: <?php $image = imagecreatefrompng(‘nathalie.png’); imagefilter($image, IMG_FILTER_BRIGHTNESS, 100); imagepng($image, ’img_filter_brightness_100.png’); imagedestroy($image); […]

Isn’t that great?! I’ll have a chance to […]

 

JS/PHP string concatenation mistype

Oct 25th, 2007

Another one from the “this is not a syntax error” department. The front-end developer is a strange beast who has to jiggle to and fro and code in several languages literally at the same time – javascript, html, css, php or some other server side language, some SQL dialect… No wonder that sometimes we make […]

Sep 10th, 2007

Simplified, but still… <?php if (!function_exists(‘file_put_contents’)) { function file_put_contents($filename, $data) { $f = @fopen($filename, ‘w’); if (!$f) { return false; } else { $bytes = fwrite($f, $data); fclose($f); return $bytes; } } } ?>
