while loop
PHP while Loop can be used for a set of codes for loops
Syntax -
while(condition){
//code to be executed
}
//code to be executed
}
Example -
<?php
$i = 0;
while($i < 5)
{
echo $i."<br>";
$i++;
}
?>
do-while loop
loop can be used on the loop on the set of PHP code such as loop. The PHP Do While Loop is guaranteed to run at least once.
Syntax -
do{
//code to be executed
}while(condition);
//code to be executed
}while(condition);
Example-
<?php
$i = 0;
do
{
echo $i."<br>";
$i++;
} while($i < 0);
?>
for loop
The PHP loop can be used to set the code for a specific time.
Syntax -
for(initialization; condition; increment/decrement){
//code to be executed
}
//code to be executed
}
Example-
<?php
for($n=1;$n<=10;$n++){
echo "$n<br/>";
}
?>
for($n=1;$n<=10;$n++){
echo "$n<br/>";
}
?>
foreach loop
The foreach loop in PHP is itating through an array. Actually, it only works on arrays, and PHP will issue an error if you try it on an unitialized variable, or a variable which does not contain an array. The foreach loop comes in two different flavors - here is an example of the first one. Oh, and since arrays have not been introduced yet, think of them as a list of items for now. In a later chapter, we will see them
Syntax -
foreach( $array as $var ){
//code to be executed
}
//code to be executed
}
Example-
<?php
$season=array("summer","winter","spring","autumn");
foreach( $season as $arr ){
echo "Season is: $arr<br />";
}
?>
$season=array("summer","winter","spring","autumn");
foreach( $season as $arr ){
echo "Season is: $arr<br />";
}
?>
