how do we print the whole elements in an array?

Answer 1

Then just use a foreach loop:
foreach($arr as $key => $value)
{
echo $value . ' ';
}

Answer 2

you can use print_r() function to print the whole array.
<?php
$arr = array(1, 2, 3);
print_r($arr);
?>

Answer 3

But it gives me "Array ( [0] => 1[1] => 2[2] => 3 )" as the output.I juz wanna print the contents only, without the indeces.

Answer 4

yeah.!! I got it..Thank you :-)

Answer 5

Don't use print_r() method. It will only print the storing format and not the individual values of the indexes. Use echo instead

Answer 6

u got to echo the the variable you specify for the array

Answer 7

use foreach loop

<?php
$arr=array("John","James","Peter");
foreach($arr as $value) {
echo $value."<br>";
}

?>
