PHP Programming

If the operating system is linux open a terminal or ssh to the server and type:

(as root)

which php-cli

or

which php5-cli

if nothing is ouputted it can't find it, then check if you've got it installed.

Debian based distro's: apt-get install php5-cli

hope this helps.

The difference between "scripting" and "programming" is largely one of semantics; they're essentially the same thing.

A purist is more likely to call writing in a usually interpreted language (such as PHP) "scripting" and writing in a usually compiled language (such as C) "programming". But either way, you're writing a set of instructions for the computer to follow, and some "scripts" can be as (or more) complicated than many "programs."

If I understand correctly it is because php is primarily a web programming language and Apache is a popular HTTP server.

To customize a taxonomy page in Drupal, you can create a custom template file for the taxonomy term view by naming it taxonomy-term--[vocabulary-machine-name].html.twig. Place this file in your theme's templates directory. Additionally, you can use the Views module to create a custom layout for displaying taxonomy terms, allowing you to define fields, filters, and sorting options. Finally, clear the cache to see your changes reflected on the taxonomy page.

There's several ways:

1) You can put square brackets on the end of a variable to create an array key inside that variable:

$names['first'] = "john"

$names['last'] = "smith"

2) You can use the array function:

$names = array('first' => "john", 'last => "smith");

a lot of people set this function out like this:

$names = array(

'first' => "john",

'last' => "smith"

);

it makes it easier to read

hope this helps

" / "

and

' / '

However the same starter must end e.g.:

echo " '; is wrong

echo ' "; is wrong

echo " ' "; is right

echo ' " '; is right

echo " " ' '; is wrong - in this case echo " " . ' '; is right.

No necessarily, PHP can be used on various other web servers, not just Apache, but Apache is the most popular. MySQL is a stand-alone database engine and is used by a lot of other stuff, not just PHP apps.

function dec2bin($val){

if($val & 1){

$rval = '1';

}else{

$rval = '0';

}

$val >>= 1;

if($val > 0){

$rval = dec2bin($val) . $rval;

}

return $rval;

}

you can use:

include($filename); // will give a warning if the file is not found

include_once($filename); // same, but only includes if the file isn't already included

require($filename); // will stop the script if the file is not found

require_once($filename); // same, but only includes if the file isn't already included

In the declaration of the receiving function, you add an ampersand.

<?php

function myWayCoolFunction( &$params)

{.....}

$x = array('1','2','3');

myWayCoolFunction($x)

?>

XAMPP just installs everything in one shot. It's a super easy setup. I think XAMPP is so much better.

You have to embed it or include it inside a special framework. You can find many ways by searching for "PDF in PHP" in a search engine.

where clause is related to mysql. If you mention the sql line here it will be easy to know more on this.

PHP data coding is softwares that allows or has frameworks which can make PHP input to it's own script language. So you may code programs for example with PHP, just that it has to be extended PHP because of new functions and features. It may also be application coding for the web.

Please see this example as below.

<?php

$first_variable = "Heloooo";

function first_method(){

print 'Heloooo';

}

class firstClass{

public $testvar="";

function firstClass(){

// initialize

$this->testvar = "Hiiiiiii";

}

function first_method_inclass(){

print 'Heloooo';

}

}

?>

Below is a simple example of how you could return a value in a PHP function.

<?php

function returnme($value)

{

return $value;

}

echo returnme('hello'); // outputs: hello

?>

To empty an array in PHP you need to use the unset function like shown below:

<?php

$array = array('hello', 'hi', 'weee');

unset($array); // empty

?>

To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result.

<?php

$array = array(1, 2, 3, 4, 5, 6, 7);

echo count($array); // outputs 7

echo sizeof($array); // outputs 7

?>

To pick random results from an array in PHP you will need to use the array_rand() function, you can select the amount of results you wish it too select too.

<?php

$array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

$rand_results = array_rand($array, 3); // will select 3 random results from the array and store in a new array

?>

To check if a value is already in an array you will need to use the in_array function like shown below!

<?php

$values = array("pizza","hello","cheese","fred");

$newvalue = "hello";

if (in_array($newvalue, $values))

{

echo "$newvalue is already in the array!";

}

?>

You don't really expect an answer here, do you?
