running php by command line

php 4.3.0 have CLI(command line interface) On by default. Today I am going to say about how to run php by command line in windows.

First of all you need to go to the php folder in your xampp by cmd. If you use svn, then you will have an error saying "Unable to load dynamic library 'E:/xampp/php/ext/php_svn.dll'- the specified module could not be found".

To solve this problem, you need to copy to following files from Apache/bin/ to php/ :

libdb43.dll
intl3_svn.dll
libapr.dll
libapriconv.dll
libaprutil.dll

These will solve the above problem.

Now to execute a php file write the command: php address_of_the_file_to_run(for example E:/xampp/htdocs/tab.php)

you can pass arguments in the command line.And one the server side, you can fetch the argument by the $argv variable, the first element is always the filename that is executing.

class constructor in php 5

In php 5, the __construct is the constructor of a class and __destruct is the destructor of the class.previously, in php 4 we are using the class name as a function as constructor of a class.let's see zend mock questions regarding this.


Question: When migrating the following code from PHP 4 to PHP 5, what should be changed?

_doSomething($param);
}

// Private method to MyClass
function _doSomething($param) {
/* Do something with $param */
}
}

class AnotherClass extends MyClass {

var $param = "foo";

function AnotherClass() {
parent::MyClass($this->param);
}
}

?>


Answer:

1. Access modifiers should be added to methods
If no access modifier is present, it treats the variable or method like public.
2. The Constructors for the objects should both be renamed to __construct
3. The use of the parent keyword has changed to 'super'
4. Constructors must have the same parameter lists

reassigning this in php 5

In php 5 you can't assign a variable to $this. It will produce a fatal error.

Question: What is wrong with the following code valid in PHP 4 but invalid in PHP 5?

reassign($b);

?>

Answer:

1. Reassigning $this in PHP 5 throws a fatal error
2. It is missing access restrictions (public,private,protected) required in PHP 5
3. Classes need to implement the OverLoad interface for this behavior in PHP 5
4. $b is now an object handle and the reassign() method needs to be declared pass-by-reference

ZEND MOCK TEST PREPARATION: comparison in php

php provides many ways to compare 2 variables. == operator doesn't check the type of the operands. it just compare the 2 operands with matching the type. === operator checks for the types of the operands also. If a string contains any numbers before having any characters in it like "1time", then === operator matches it with integer value "1". Any string without initial number are treated as 0 when converted to integer. let's see a zend mock question for php 5 certification.


Question: Which of the following comparisons will evaluate to true?

Answer:

1. 't' == t
2. 1 === "1time"
3. "top" == 0
4. "top" === 0
5. 1 == "1time"
