| Answer |
PayPal Recurring Payments allows you to bill a buyer for a
fixed amount of money on a fixed schedule. The buyer signs
up for recurring payments during checkout from your site.
Consider the following examples:
A buyer purchases a subscription to a magazine or
newsletter from your site and agrees to pay a monthly fee.
A buyer agrees to pay an Internet Service Provider a flat
fee on a semi-annual basis to host a website.
These examples represent payment transactions that reoccur
periodically and are for a fixed amount.
When you create recurring payments for a buyer, you create
a recurring payments profile. The profile contains
information about the recurring payments, including details
for an optional trial period and a regular payment period.
Each of these subscription periods contains information
about the payment frequency and payment amounts, including
shipping and tax, if applicable.
After a profile is created, PayPal automatically queues
payments based on the billing start date, billing
frequency, and billing amount, until the profile expires or
is canceled by the merchant. The buyer can also cancel the
recurring payment profile for profiles creating using
Express Checkout.
Note that for profiles created using Express Checkout, the
queued payments are funded using the normal funding source
hierarchy within the buyer's PayPal account.
After the recurring payments profile is created, you can
view recurring payments details or cancel the recurring
payments profile from your PayPal account.You can also
access recurring payments reports from the PayPal Business
Overview page.

##
##This will work for PHP 5.3 -
$url1="yahoo.com";
$url2="yahoo.co.in";
$url3="hotmail.org";
$domain1 = strstr($url1, '.', true);
$domain2 = strstr($url2, '.', true);
$domain3 = strstr($url3, '.', true);
echo $domain1, $domain2, $domain3;
##
## For Older PHP (<5.2.8), this code will follow -
$url1="yahoo.com";
$url2="yahoo.co.in";
$url3="hotmail.org";
$domain1 = substr($url1, 0, strpos($url1, '.') );
$domain2 = substr($url2, 0, strpos($url2, '.') );
$domain3 = substr($url3, 0, strpos($url3, '.') );
echo $domain1, $domain2, $domain3;

| Question |
What is fulltextsearch |
Rank |
Answer Posted By |

Interview Question Submitted By :: Rohit Singh |
|
I also faced this Question!! |
© ALL Interview .com |
| Answer |
MySQL has support for full-text indexing and searching. A
full-text index in MySQL is an index of type FULLTEXT.
FULLTEXT indexes can be used only with MyISAM tables; they
can be created from CHAR, VARCHAR, or TEXT columns as part
of a CREATE TABLE statement or added later using ALTER
TABLE or CREATE INDEX. For large datasets, it is much
faster to load your data into a table that has no FULLTEXT
index, and then create the index afterwards, than to load
data into a table that has an existing FULLTEXT index.
Constraints on full-text searching are listed in Section
12.7.4, “Full-Text Restrictions”.
Full-text searching is performed with the MATCH() function.
mysql> CREATE TABLE articles (
-> id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY
KEY,
-> title VARCHAR(200),
-> body TEXT,
-> FULLTEXT (title,body)
-> );  |
0 | Jagpreet |
| |
| |
| Answer |
MATCH (col1,col2,...) AGAINST (expr [search_modifier])
A full-text index in MySQL is an index of type FULLTEXT.
Full-text indexes can be used only with MyISAM tables, and
can be created only for CHAR, VARCHAR, or TEXT columns. A
FULLTEXT index definition can be given in the CREATE TABLE
statement when a table is created, or added later using
ALTER TABLE or CREATE INDEX.
For large data sets, it is much faster to load your data
into a table that has no FULLTEXT index and then create the
index after that, than to load data into a table that has an
existing FULLTEXT index.
Full-text searching is performed using MATCH() ... AGAINST
syntax.
MATCH() takes a comma-separated list that names the columns
to be searched.
AGAINST takes a string to search for, and an optional
modifier that indicates what type of search to perform.
Three types of full-text searches
1. A Boolean search interprets the search string using the
rules of a special query language.
2. A natural language search interprets the search string as
a phrase in natural human language (a phrase in free text).
There are no special operators.
3. A query expansion search is a modification of a natural
language search.  |

How to differentiate isset and empty

Interview Question Submitted By :: Rakesh Kumar Nautiyal |

I also faced this Question!! |
© ALL Interview .com |
| Answer |
isset -> this variable handling functions determine whether
a variable is set . It checks whether a variable is set
even though it is empty.
empty -> as the term itself has already given a sign that
it would related to something that's empty, this variable
handling functions determine whether a variable is empty.
It checks whether a variable has a value whether it's empty
string, zero(0), or not set at all.  |
0 | P .g .senthilkumar |
| |
| |
| Answer |
isset is used for checking whether variable is set or not
and empty checks whether it is empty  |
0 | Rahul Shelar |
| |
| |
| Answer |
actually, !isset and empty are one and same thing...  |
0 | Rafique |
| |
| |
| Answer |
isset() will ONLY return true when the value of the variable
is not NULL (and thereby the variable is at least defined).
empty() will return true when the value of the variable is
deemed to be an "empty" value, typically this means 0, "0",
NULL, FALSE and empty string, anything else is not empty.
Some examples
FALSE == isset($foo);
TRUE == empty($foo);
$foo = NULL;
FALSE == isset($foo);
TRUE == empty($foo);
$foo = 0;
TRUE == isset($foo);
TRUE == empty($foo);
$foo = 1;
TRUE == isset($foo);
FALSE == empty($foo);  |
0 | Amit |

| Answer |
isset is used to check whether the variable is set or

where as empty is used to check whether variable contains a

Hey guys.. don't be confused with the values and nulls.
Unique key conforms only the values to be unique. Since the
nulls are not any kind of value, they can occur as many
times as they can.. nulls are nothing..  |
0 | Ravin |
| |
| |
| Answer |
Yes, we can use multiple Null values in case of Unique Key
Column. This is one the main difference between Unique Key
and Primary Key that Unique Key always allows multiple
entries of Null Statement where as Primary Key never allows
this.
I am hereby giving you a very very basic example which
suggests that Unique Key can have more than one Null
Statement :-
SQL> create table abcd(name varchar2(10) unique);
Table created.
**********************
Now insert the values :-
SQL> insert into abcd(name)values('amit');
1 row created.
SQL> insert into abcd(name)values('ami');
1 row created.
SQL> insert into abcd(name)values(null);
1 row created.
SQL> insert into abcd(name)values(null);
1 row created.
SQL> insert into abcd(name)values(null);
1 row created.
SQL> commit;
Commit complete.
SQL> select * from abcd;
