for-each loop
Some of us have the question that why we use for-each when
we have already for loop.
So that the answer is for-each loop is used for the array,
but how?
Coming to the Syntax:
foreach($arrayname as $value)
{
// code for execution
}
EXAMPLE
$myname=array(“softfive”,”soft”)
foreach($myname as $value)
{
echo $value.” , “;
}
Output
Softfive , soft
WHILE Loops
Now coming to the while loop, many of us used the while
loop. The syntax of while loop is same as other programming languages like
C,C#,etc.
Syntax:
while(condition)
{
// code for execution
}
Note: In case of while when the condition is true then code
executed.
Do-While loop
When we are talking about while loop it is common to come
do-while loop.
Syntax:
do{
// code for execution
}while(condition);
EXAMPLE
$a=1;
while($a=5)
{
++$a;
echo $a.”<br />”;
}
Output
2
3
4
5
6
IMPORTANT =>
Many of us have the confusion that what is the difference
between ‘while’ and ‘do-while’ loop
So the main difference is
WHILE EXECUTED IF THE
CONDITION IS TRUE whereas DO WHILE EXECUTED AT LEAST ONE TIME IF THE CONDITION
IS FALSE.
EXAMPLE of do-while
$a=1
do{
echo $a;
}while($a=3);
Output
1
