PHP Programming Guide

Want to make your page more popular on the internet, then why not maximize deep tagging to sites that have the highest page-ranking around. It gives the spiders/bots something to follow in terms of your page, from the higher ranked ones down the line.

Sort of like breadcrumbs, it leads the bot from up the scale, pages that are major such as The New York Post down to your page from a link that you made to a specific article to that page. Be creative and to get more out of a page, maximize tools available from the many forum contributors but be kind enough to send a few tricks you yourself may be using the group doesn’t know so goodwill spreads around.

Launching too many pages at once send the wrong signal over the internet with a sure spam label sent your way. It can cost you a lot of blocked content preventing legit users form getting the pages they need when they need it. It also saves on the time it takes to explain to your clients why their pages weren’t online so use a staggered launch plan to allow ample time for the content/page to get out there, rather than bombarding them all over the place.

The risk of spam is simply great that sites have been sensitized to such mass launching of pages. Think out your distribution policy and save time by getting pages out as they are needed ensuring ample time for dissemination.

Now that’s the problem why your page has been suffering in terms of visitors lately. Google’s bot checks for verbatim copies of content and tends to skip ones that do have duplicates. You also suffer from ailing pageranking which is also determined by the bots activities.

They were initially called spiders/bots but they can be easily described as indexing programs that scours the web for new content. Having copied content tells these bots to skip your page thus the low ratings and page visits. This also exposes you to plagiarism charges so be sure to quote contents and give credit for those you simply can’t live without.

Developing a web page should be a straightforward process that follows well accepted standards that may not be written but are used and known to work in the wild that is the internet. The planning of a web framework should follow the following guidelines in order to work best and sort out issues in the long run.
A well though out framework is time-saving, meaning maximizing code and using/re-using as necessary should be a must to shorten and make it more efficient. Reliability of the page is another issue that should be prioritized to as well as adherence to well-structured patterns that are widely accepted in the development community. That along with many other areas to consider such as performance (easily addressable through caching or some other method) .

The function reverses the contents of an array with the keys as values and the values as keys with the following syntax:

array_flip(array)

Legend:
array – array(name of the array) to be flipped

Sample Code:
$a=array(0=>“Lizard”,1=>”Mouse”,2=>”Fish”);print_r(array_flip($a));
?>

Output :
Array([Lizard] => 0 [Mouse] => 1 [Fish] => 2 )

PHP array_intersect() function
Compares two or more arrays, returning an array with the keys and values fromt he first array if it is present in all the other arrays.

Syntax:
array_intersect(array1, array2……)

Legend:
array1 – the first array to which the others will be compared with
array2 – array to be compared with the first array
array3 – array to be again compared with the first array

Sample:
$a1=array(0=>“Mouse”,1=>”Chicken”,2=>”Gnat”);
$a2=array(3=>”Mouse”,4=>”Gnat”,5=>”Lizard”);
print_r(array_intersect($a1,$a2));
?>

Output:
Array ([0] => mouse [2] => Gnat )

This function compares the keys of one array with as many as you like. Only the keys of the first array is compared to another or as many as you like. The syntax goes like this:

array_diff_ukey(array1, array2,array3….,fucntion)

Legend:
array1 – is the array to be compared with the other array’s
function – is the name of a user named function which is a condition.

Sample Program:
function urfunction($x1,$x2)
{
if ($x1===$x2)
{
return 0;
}
if ($x1>$x2)
{
return 1;
}
else
{
return -1;
}
}
$x1-array(0=>”Dog”,1=>”Cat”,2=>”Horse” );
$x2=array(3=>”Rat”,1=>”Bird”,5=>”Monkey” )’
print_r(array_diff_ukey($x1,$x2,”urfunction”));
?>

The output would be : Array( [0] => Dog [2] => Horse)

Next in line is array_diff_uassoc() function which compares two or more arrays while checking for differences before comparing the keys with a user-defined location. It then returns an array withthe keys and values from the first array(to which all the values were comapred against) it the function allows it. Syntax is as follows : array_diff_uassoc(array1,array2,array3….,function). with a sample below of how it is used.

function userdefined($v1,$v2)
{
if ($v1 === $v2)
{
return 0;
}
if ($v1 > $v2)
{
return 1;
}
else
{
return -1;
}
}
$a1=array(0=>”Dog”,1=>”Cat”,2=>”Horse”)
$a2=array(3=>”Dog”,1=>”Cat”,5=>”Horse”)
print_r(array_diff_uassoc($a1,$a2,”userdefined”));
?>

which results in the following output : Array( [0] => Dog [2] => Horse). For an example of the same function with two or more assigned arrays to the function:

function userdefined($v1,$v2)
{
if ($v1 === $v2)
{
return 0;
}
if ($v1 > $v2)
{
return 1;
}
else
{
return -1;
}
}
$a1=array(0=>”Dog”,1=>”Cat”,2=>”Horse”)
$a2=array(3=>”Dog”,1=>”Cat”,5=>”Horse”)
$a3=array(6=>”Onyx”,0=>”Dog”,5=>”Horse”)
print_r(array_diff_uassoc($a1,$a2,$a3,”userdefined”));
?>

Which in turn, gives you : Array ([2] => Horse )

So we see the different array_diff function variants and the diffeerent ways they are used to compare the values of one or more arrays with one another.

The next array comparison functions is the array_diff_assoc(array1,array2,array3,array3…..), usage is similar with all of these array_diff functions varying only in the way the comparisons are done. Below is sample code for array_diff_assoc:

$a1=array(0=>“Mouse”,1=>”Cat”,2=>”Dog”);
$a2=array(0=>”Lizard”,1=>”Dog”,2=>”Cat”);
$a3=array(0=>”Dog”,1=>”Cat”,2=>”Mouse”);
print_r(array_diff_assoc($a1,$a2,$a3))
?>

Giving you : Array ([0] => Mouse [2] => Dog).

Next we have the array_diff_key() function compares two or more arrays and returns an array with the keys and values from the first array only if the key is not present in the other arrays. Syntax is array_diff_key(array1,array2,array3……)which is similar to the other array_diff functions.

Sample usage:
$a1=array(0=>“Mouse”,1=>”Cat”,2=>”Dog”);
$a2=array(2=>”Fish”,3=>”Rat”,4=>”Bee”);
$a3=array(5=>”Dog”,6=>”Cat”,7=>”Fish”)
print_r(array_diff_key($a1,$a2,$a3));
?>

Giving you : Array([0] => Mouse [0] => Cat)

The first function, array_diff() is used for comparing several tables or arrays which gives an array with the keys and values from the first array if the value is not available in the other arrays. Syntax is as follows : array_diff(array1,array2,array3……), where array 1 is the table to which all the other arrays will be compared to. The 2nd array(array 2) is an array that is compared with the first array and so on and so forth. Below is sample code of its use and the outcome of the functions comparison :

$a1=array(0=>“Mouse”,1=>”Cat”,2=>”Dog”);
$a2=array(3=>”Dog”,4=>”Cat”,5=>”Lizard”);
print_r(array_diff($a1,$a2));
?>

Giving you the result : Array( [0] =>Mouse )

This function combines two arrays where the first array is treated as the key and the second array as the contents of the said table. The syntax goes like this : array_combine(array1,array2), wherein the array1 is the table which contains the keys values, and the array2 is the contents. It should be noted that these two tables or array�s should have equal amounts of contents for it would become problematic if there was an error in the combination process. An example of the process is shown below:

$a1=array('a','b','c','d')
$a2=array2("Mouse","Rat","Rodent","Mice")
print_r(array_combine($a1,$a2))
?>

The output of which would give us a single table :

Array ( [a] => Mouse [b] => Rat [c] => Rodent [d] => Mice )

The function combined the two tables giving a single table that combines the keys and the contents. More in-depth discussion on the different array functions which in future posts would be the backbone of applications we will be building.
