IPT Flashcards
Deals with an integration approaches and
techniques that connect different components of
IT infrastructure.
Integrative Programming
containers for storing data values.
PHP variables
often used to output data to the screen.
echo
Also known as Language processors
LANGUAGE TRANSLATORS
defines a formal language for combining set of computing
instructions to generate an output.
Programming language
used to perform operations on variables and values.
Operators
used with numeric values to
perform common arithmetical operations, such as addition,
subtraction, multiplication and so on.
arithmetic operators
used with numeric values to write
a value to a variable.
assignment operators
The basic assignment operator in PHP. It means that the left
operand gets set to the value of the assignment expression on the
right.
=
used to compare two values
(number or string):
Comparison operators
used to increment a variable’s value.
increment operators
used to decrement a variable’s value
decrement operators
used to combine conditional
statements.
logical operators
executes some code if one condition is true.
if statement
executes some code if a condition is true and
another code if that condition is false.
if…else statement
executes different codes for more than
two conditions.
if…elseif…else statement
to select one of many blocks of code to be executed.
switch statement
executes a block of code if the specified condition is
true.
while loop
will always execute the block of code once,
it will then check the condition, and repeat the loop while the
specified condition is true.
do…while loop
is used when you know in advance how many times the
script should run.
for loop
works only on arrays and is used to loop through each key/value pair in an array.
foreach loop
loops through a block of code for each element in an array
for each loop
loops through a block of code a specifies number of times
for loops
stores multiple values in one single variable.
array
used to create an array.
array()
an array with a numeric index. Values are stored and accessed in linear fashion.
Indexed / Numeric arrays
an array with strings as index. This stores element values in association with key values rather than in a strict linear index order.
Associative arrays
an array containing one or more arrays and values are accessed using multiple indices.
Multidimensional arrays
