lixlpixel php code snippets | string handling


this will "columnize" your long text.

 long text, especially on large screens is really hard to read.

 thats why in the "real world" newspapers use columns to layout text.

 

 with this script you just paste the text and specify the numbers of columns.

 it will split the text into more reader-friendly chunks.
