  1. Hello, i have been studying this book "php 6 and mysql 5 for dynamic website" on my own... i am happy i finished studying this book and this gave me an advanced basic understanding in PHP and MYSQL. Please i will like some recommendations on which php and mysql book to study/buy next in order to have more advanced knowledge in php and mysql. So as to be able to create a section in my web application to read pdf files. And also to be able to create an e-commerce application. Thank you, Jai.
  2. I'm learning from various sources and can usually puzzle out what's going on, but this has me a bit stumped. I came across this code at http://www.webdeveloper.com/forum/showthread.php?224180-JQuery-how-does-it-s-insides-work: function X(css){ //dom utility //a couple of node harvesters, using id and tag name... function el(id){ return document.getElementById(id);} function tags(elm){return document.getElementsByTagName(elm);} //collect output: var out=[]; if(css[0]=="#"){//id out.push(el(css.slice(1))); }else{//tags out=out.concat([].slice.call(tags(css))); };//end if id or tagName //define some methods for the utility: var meths={ hide:function(a){a.style.display="none";}, show:function(a){a.style.display="";}, remove:function(a){a.parentNode.removeChild(a);}, color:function(a){a.style.color=this||a.style.color;}, size:function(a){a.style.fontSize=this||a.style.fontSize;} };//end meths //bind the methods to the collection array: for(var meth in meths)(function(n,m){ out[n]=function(x){out.map(m,x); return out;} }(meth, meths[meth]));//next method return out; }//end X dom utility For the life of me, I am having a hard time figuring out how the Javascript is running in the for loop binding the methods to the collection array. I realize this is advanced, but if someone could walk through what is happening, and how the methods are being called with variables correctly linked to their respective methods, it would be appreciated. This is cool, if only I could understand how it is occurring.
