JavaScript Snippet – Convert HTML Table To 2D Array

A few days ago I was working on manipulating data that I found in Wikipedia. The data was in a table where the colspans and rowspans were making it difficult to simply programmatically pull data. Then I started looking into code to turn HTML table to JSON but for some reason the rowspans were still causing issues. Finally, I decided to just write a quick and dirty function to get the job done:

The cool thing about this function is that in the case of cells that span multiple columns and/or rows the value in that cell will be written to each corresponding sub-array value.

PHP Snippet – array_splice_assoc(…)

Recently I was working on something that required inserting key-value pairs into an array after a specific key in PHP. As I was looking through stackoverflow answers I realized that there was no awesome answer that really jumped out at me. Therefore I decided to take a few minutes to just write my own array_splice_assoc() function to get the job done:

As you can see this function takes the same parameters that array_splice() does but the difference is that the offset can be a string in this key which refers to the key after which the new array elements should be inserted.

One important thing to note is that if you try to insert a key-value pair in which the key exists before or at the offset, your key-value pair will not be inserted. On the other hand if you try to insert a key-value pair in which the key exists after offset, your value will replace the previous one.

Have fun! :cool:

JavaScript – Faking Native Functions

The other day I kind of just wanted a reason to write a Gist and embed it on my site using this method. What I came up with was a quick way to make all functions appear to be native:

Here is an example of what happens:

function alertAndReturn() {
  alert.apply(this, arguments);
  return arguments;
}

alert(alertAndReturn); // function alertAndReturn() { [native code] }
alert(function(){});   // function () { [native code] }

I have no clue when this would be useful in the real world but if you need it, here it is! 8-)
