I want to use php arrays and foreach loops to output the needed html.
The php code I have thus far is:
<?php
$data = array("navigation");
$data['navigation']['Home'] = base_url();
$data['navigation']['Pages'] = base_url('pages');
$data['navigation']['Pages']['About'] = base_url('pages/about');
echo '<ul>';
foreach($data as $nav) {
foreach($nav as $subNavKey => $subNavHref) {
echo "<li><a href='$subNavHref'>$subNavKey</a>";
}
}
echo '</ul>';
?>
I was thinking I would need three foreach loops nested but php warnings/errors are generated when the third loop is reached on lines such as:
$data['navigation']['Home'] = base_url();
$data['navigation']['Pages'] = base_url('pages');
I'm not quite sure how to test for 3rd level depths such as:
$data['navigation']['Pages']['About'] = base_url('pages/about');
Also, outputting the needed li and ul tags in the proper positions has given me trouble aswell.
Use recursion
$data['navigation']['Home'] = base_url();
$data['navigation']['Pages'] = base_url('pages');
$data['navigation']['Pages']['About'] = base_url('pages/about');
$data['navigation']['Pages']['About']['Team'] = base_url('pages/team');
$data['navigation']['Pages']['About']['Team']['Nate'] = base_url('pages/nate');
echo "<ul>"
print_list($data);
echo "</ul>"
function print_list($menu) {
foreach($menu as $key=>$item) {
echo "<li>";
if(is_array($item)) {
echo "<ul>";
print_list($item);
echo "</ul>";
} else {
echo "<a href='{$val}'>$key</a>";
}
echo "</li>";
}
}
<?php
function nav($data) {
$html = '<ul>';
foreach ($data as $k => $v) {
if (is_array($v)) {
$html .= "<li>$k" . nav($v) . "</li>";
}
else {
$html .= "<li><a href='$k'>$v</a>";
}
}
$html .= '</ul>';
return $html;
}
echo nav($data);
A recursive function can get the job done:
$items = array(
"Home",
"Pages" => array(
"About",
"Services",
"Products",
"Contact",
"FAQs",
"Sitemap",
"Privacy Policy",
"Column Layouts" => array(
"1 Column",
"2 Column (Left Sidebar)",
"2 Column (Right Sidebar)",
"3 Column",
"4 Column"
)
)
);
function getMenu($array) {
foreach($array as $key => $value) {
if(is_array($value)) {
echo "<li>" . $key . "</li>";
echo "<ul>";
getMenu($value);
echo "</ul>";
} else {
echo "<li>" . $value . "</li>";
}
}
}
echo "<ul>";
getMenu($items);
echo "</ul>";
Output:
You should use a recursive function, for example (Working Demo):
function makeMenu($array)
{
$menu = '';
foreach($array as $key => $value) {
if(is_array($value)) {
$menu .= '<li>' . $key . '<ul>' . makeMenu($value) . '</ul></li>';
}
else {
$menu .= "<li><a href='". $value ."'>" . $value ."</a></li>";
}
}
return $menu;
}
Then call it like:
$data = array(
"Home",
"Pages" => array("About", "Services"),
"Column Layouts" => array("1 Column", "2 Column (Left Sidebar)")
);
echo '<ul>' . makeMenu($data) . '</ul>';

I have very little experience with PHP, but I'm taking a class that has PHP review exercises. One of them is to create a function that uses a loop to return all values of an array except the first value in an unordered list. I'm assuming there's a way to do this using a foreach loop but cannot figure out how. This is what I had but I feel like I am far off:
<?php
$array = array('myName' => 'Becca', 'favColor' => 'violet', 'favMovie' => 'Empire Strikes Back', 'favBook' => 'Lullaby', 'favWeb' => 'twitter.com');
$myName = $array['myName'];
$favColor = $array['favColor'];
$favMovie = $array['favMovie'];
$favBook = $array['favBook'];
$favWeb = $array['favWeb'];
echo '<h1>' . $myName . '</h1>';
function my_function() {
foreach($array == $myName){
echo '<ul>'
. '<li>' . $favColor . '</li>'
. '<li>' . $favMovie . '</li>'
. '<li>' . $favBook . '</li>'
. '<li>' . $favWeb . '</li>'
. '</ul>';
}
}
my_function();
?>
The correct syntax of foreach is
foreach (array_expression as $key => $value)
instead of
foreach($array == $myName){
function that uses a loop to return all values of an array except the
first value
I'm not sure, what exactly you mean by except the first value. If you are trying to remove first element from the array. Then you could have used array_shift
If you are supposed to use loop then
$count = 0;
foreach ($array as $key => $value)
{
if ($count!=0)
{
// your code
}
$count++;
}
Change the code to following
<?php
$array = array('myName' => 'Becca', 'favColor' => 'violet', 'favMovie' => 'Empire Strikes Back', 'favBook' => 'Lullaby', 'favWeb' => 'twitter.com');
$myName = $array['myName'];
echo '<h1>' . $myName . '</h1>';
function my_function($array)
{
$count = 0;
echo "<ul>";
foreach($array as $key => $value)
{
if($key != "myName")
{
echo "<li>".$value."</li>";
}
}
echo "</ul>";
}
my_function($array);
I'm Trying to format the output of an array using php but I can't seem to get the keys and values on the same line. I've listed the code that I'm using to display the keys and values but this code outputs the keys and values on different lines
function olLiTree($tree)
{
echo '<pre>';
foreach($tree as $key => $item) {
if (is_array($item)) {
echo '<pre>', $key ;
olLiTree($item);
echo '</pre>';
} else {
echo '<pre>', $item, '</pre>';
}
}
echo '</ul>';
}
print(olLiTree($results));
Use <ul> <li> .... </li></ul>. Also remove comma(,) because PHP use dot(.) for concat string.
function olLiTree($tree)
{
echo '<ul>';
foreach($tree as $key => $item) {
if (is_array($item)) {
echo '<li>'. $key ;
olLiTree($item);
echo '</li>';
} else {
echo '<li>' .$item. '</li>';
}
}
echo '</ul>';
}
print(olLiTree($results));
You use comma , instead of dot .
for string concatenation php use dot
function olLiTree($tree)
{
echo '<pre>';
foreach($tree as $key => $item) {
if (is_array($item)) {
echo '<pre>'. $key ;
olLiTree($item);
echo '</pre>';
} else {
echo '<pre>' . $item. '</pre>';
}
}
echo '</ul>';
}
print(olLiTree($results));
I have an array with some items. Each array could have (or not) an subarray, also with some items.
How can I call the subarray in a loop? It is difficult to describe, here is the code. I know the code/syntax is not correct, but the syntax should clarify my problem:
<?php
$subitemsA = array(
'subA1' => array('num'=>65, 'text'=>'Labor', 'url'=>'#'),
'subA2' => array('num'=>44, 'text'=>'Rare', 'url'=>'#'),
);
$subitemsB = array(
'subB1' => array('num'=>0, 'text'=>'subB1', 'url'=>'#'),
'subB2' => array('num'=>0, 'text'=>'subB2', 'url'=>'#'),
'subB3' => array('num'=>0, 'text'=>'subB3', 'url'=>'#')
);
$navArray = array(
'Home' => array('num'=>0, 'text'=>'Home', 'url'=>'#'),
'Info' => array('num'=>0, 'text'=>'Info', 'url'=>'#', 'subArray'=>$subitemsA),
'Sport' => array('num'=>0, 'text'=>'Sport', 'url'=>'#', 'subArray'=>$subitemsB),
);
$html = '';
foreach($navArray as $item) {
$html .= "<li>";
$html .= "<a href='{$item['url']}'><i class='abc'></i>{$item['text']}</a>\n";
if (count($navArray) > 3) {
foreach($navArray.subArray as $subitem) {
$html .= "<li>";
$html .= "<a href='{$subitem['url']}'>{$subitem['text']}</a>\n";
$html .= "</li>";
}
}
$html .= "</li>";
}
The first foreach loop works. But how can I access the subArray of Info and Sport?
You need a three level foreach for this to work -
foreach($navArray as $key => $item) {
$html .= "<li>";
$html .= "<a href='{$item['url']}'><i class='abc'></i>{$item['text']}</a>\n";
foreach ($item as $itemkey => $value) {
if (is_array($value)) { //Now Check if $value is an array
foreach($value as $valuekey => $subitem) { //Loop through $value
$html .= "<li>";
$html .= "<a href='{$subitem['url']}'>{$subitem['text']}</a>\n";
$html .= "</li>";
}
}
}
$html .= "</li>";
}
This is an answer to your question in more general way: How to deal with multi-level nested array using recursion and template.
function parseArray(array $navArray, &$html, $depth = 0) {
foreach ($navArray as $item) {
$html .= "<li>";
// this function use template to create html
$html .= toHtml($item['url'], $item['text'], $depth);
foreach ($item as $subItem) {
if (is_array($subItem)) {
// use recursion to parse deeper level of subarray
parseArray($item, $html, $depth + 1);
}
}
$html .= "</li>";
}
}
function toHtml($url, $text, $depth)
{
$template = '';
if ($depth == 0) {
$template = '<a href=\'{{url}}\'><i class=\'abc\'></i>{{text}}</a>\n';
} elseif ($depth >= 1) {
$template = '<a href=\'{{url}}\'>{{text}}</a>\n';
}
// define more template for deeper level here if you want
$template = str_replace('{{url}}', $url, $template);
$template = str_replace('{{text}}', $text, $template);
return $template;
}
$html = '';
parseArray($navArray, $html);
Just hurrily forge this code out of mind, haven't test it yet. Hope it help.
Regards,
I want generate a link using two array: the first one contains addresses; the second one contains text.
I want have:
- text3
- text3
- text3
to do so I tried like this but I can't generate texts.
<ul>
<?php
isset($_GET["page"]) ? $page=$_GET["page"] : $page="home";
$vocimenu=array("address1","address2","address3");
$nomimenu=array("text1","text2","text3");
$nome=array_values($nomimenu);
foreach($vocimenu as $voce) {
echo "<li>";
if($page!=$voce) echo '<a href="?page='.$voce.'">';
echo $nome;
if($page!=$voce) echo "</a>";
echo "</li>";
}
?>
</ul>
You can use one array
isset($_GET["page"]) ? $page=$_GET["page"] : $page="home";
$links=array("address1"=>"text1","address2"=>"text2","address3"=>"text3");
foreach($links as $href=>$text){
if($page!=$voce){
echo ''.$text.'';
}else{
echo $text;
}
}
This should work:
isset($_GET["page"]) ? $page=$_GET["page"] : $page="home";
$vocimenu=array("address1","address2","address3");
$nomimenu=array("text1","text2","text3");
//since you're using two arrays, foreach is not the way to go
//you need a counter so you can get elements from each array
for ($i=0;$i<count($vocimenu);$i++) {
echo "<li>";
if($page!=$voce) echo '<a href="?page='.$vocimenu[$i].'">';
echo $nomimenu[$i];
if($page!=$voce) echo "</a>";
echo "</li>";
}
An alternate option is to do it like this, but that could make some of your other code less flexible:
$array = array("address1"=>"value1","address2"=>"value2",...);
foreach($array as $address=>$value){
echo "<li>";
if($page!=$voce) echo '<a href="?page='.$address.'">';
echo $value;
if($page!=$voce) echo "</a>";
echo "</li>";
}
It would be much easier if you create an associative array:
$menu = array(
"fmp_trama" => "Full Metal Panic!",
"fumoffu_trama" => "Full Metal Panic? Fumoffu",
"fmp_tsr" => "Full Metal Panic! TSR"
);
echo '<ul>';
foreach ($menu as $key => $value) {
echo "<li>";
if($page != $key) {
echo sprintf('%s', $key, $value);
}
else {
echo sprintf('<span>%s</span>', $value);
}
echo "</li>";
}
echo '</ul>';
You can build the array like this: (if you are bound to the 2 array structure)
$menu = array_combine($vocimenu, $nomimenu);
I have a multi dimensional array with the structure:
Name
Address
Area
Area Type 1
Area Type 2
Area Type 2
I have a loop that grabs the Name and Address for each business and echos them out. Now what I want to be able to do is now grab the area and chuck that out for each business. My loop thus far is as follows:
foreach ($data AS $key => $value) {
echo '<ul>';
echo '<li>';
echo $value['Name'];
echo '</li>';
echo '<li>';
echo $value['Address'];
echo '</li>';
echo '<li>';
foreach ($data as $row) {
echo $data['Area'];
}
echo '</li>';
echo '</ul>';
}
I can output all the Areas in one go with:
foreach($data as $row)
{
foreach($row['Area'] as $areaout)
{
echo $areaout;
}
}
But I need it to echo out with it's respective name and address
Shouldn't you simply replace
foreach ($foo as $row) {
echo $foo['Area'];
}
by
echo '<ul>';
foreach ($value['Area'] as $v) {
echo '<li>' . $v . '</li>';
}
echo '</ul>'
?
