Printing specific items in an array
I'm a newbie and trying to do this for my college class. I have created an array called birds: Here is my code:
<?php // This script creates an array called birds and then prints out the birds 1-3 and then prints the birds 0,, 2 and 4
$birds = array ("Whip-poor-will|Chickadee|Pileated Woodpecker|Blue Jay|Rufus-sided Towhee|Scarlet Tanager");
I need to print out specific items within the array using foreach. would the next code be
Foreach($birds as $key =>value){pri开发者_如何学Cnt "$key $1,2,3 <br>";}
The array needs to be initialized with this syntax:
$birds = array(
"Whip-poor-will",
"Chickadee",
"Pileated Woodpecker",
"Blue Jay",
"Rufus-sided Townee",
"Scarlet Tanager");
And the foreach
would be:
foreach($birds as $key => $value)
{
echo "$key - $value<br/>";
}
If you wanted to get data for specific elements of the array, they are referenced by index:
echo $birds[0];
//output will be: Whip-poor-will
echo $birds[2];
//output will be: Pileated Woodpecker
A bit too picky, perhaps, but it's actually <br />
(with a space). At least in XHTML standard code.
