This is an array i have
<?php
$page['Home']='index.html';
$page['Service']='services.html';
?>
How do i get to echo something like this for individual one like
Home is at index.html
and again how can i do this through a loop and echo all?
foreach($page as $key => $value) {
echo "$key is at $value";
}
For 'without loop' version I'll just ask "why?"
key($page).' is at '.$page[key($page)];
Without a loop, just for the kicks of it...
You can either convert the array to a non-associative one, by doing:
$page = array_values($page);
And then acessing each element by it's zero-based index:
echo $page[0]; // 'index.html'
echo $page[1]; // 'services.html'
Or you can use a slightly more complicated version:
$value = array_slice($page, 0, 1);
echo key($value); // Home
echo current($value); // index.html
$value = array_slice($page, 1, 1);
echo key($value); // Service
echo current($value); // services.html
If you must not use a loop (why?), you could use array_walk
,
function printer($v, $k) {
echo "$k is at $v\n";
}
array_walk($page, "printer");
Echo key and value of an array without and with loop
$array = array(
'kk6NFKK'=>'name',
'nnbDDD'=>'claGg',
'nnbDDD'=>'kaoOPOP',
'nnbDDD'=>'JWIDE4',
'nnbDDD'=>'lopO'
);
print_r(each($array));
Output
Array
(
[1] => name
[value] => name
[0] => kk6NFKK
[key] => kk6NFKK
)
function displayArrayValue($array,$key) {
if (array_key_exists($key,$array)) echo "$key is at ".$array[$key];
}
displayArrayValue($page, "Service");
How to echo key and value of an array without and with loop
$keys = array_keys($page);
implode(',',$keys);
echo $keys[0].' is at '.$page['Home'];
My version without a loop would be like this:
echo implode(
"\n",
array_map(
function ($k, $v) {
return "$k is at $v";
},
array_keys($page),
array_values($page)
)
);
A recursive function for a change;) I use it to output the media information for videos etc elements of which can use nested array / attributes.
function custom_print_array($arr = array()) {
$output = '';
foreach($arr as $key => $val) {
if(is_array($val)){
$output .= '<li><strong>' . ucwords(str_replace('_',' ', $key)) . ':</strong><ul class="children">' . custom_print_array($val) . '</ul>' . '</li>';
}
else {
$output .= '<li><strong>' . ucwords(str_replace('_',' ', $key)) . ':</strong> ' . $val . '</li>';
}
}
return $output;
}
You can try following code:
foreach ($arry as $key => $value)
{
echo $key;
foreach ($value as $val)
{
echo $val;
}
}
foreach
.
