i am trying to automate my navigation links. How do I automatically echo out foreach. I am getting undefined offset right now... And can I ignore the first item in the array (i.e. title)?
'control' => array( 0=>'Controls',
1=> array('Add school','add.school.php'),
2=> array('Add doctor','add.doctor.php'),
3=> array('Add playgroup','add.play.php'),
4=> array('Suggestions','suggestion.php'),
5=> array('List tutor service','list.tutor.php'),
6=> array('Create playgroup','create.play.php'),
7=> array('Dashboard', 'dashboard.php')
),
<?php
foreach ($nav['control'] as $value=>$key){
echo''.$key[1].'';
}
?>
Numeric arrays are indexed from 0, not 1. You want [1] and [0] respectively.
// for key => value is more nature.
foreach ($nav['control'] as $key => $value){
// should skip the first.
if ($key === 0) {
continue;
}
// array is 0 base indexed.
echo''.$value[0].'';
}
foreach ($nav['control'] as $value=>$key) {
echo''.$key[0].'';
}
a nested array requires nested loop.
foreach($array as $key => $value){
if($key != 0){
foreach($value as $k => $v){
if($k == 0){ $title = $v;}
if($k == 1){ $link = $v;}
}
//put code to run for each entry here (i.e. <div> tags, echo $title and $link)
}
my personal practice when i only use two fields is to push the first into the array['id'] and the second as the value i.e.
while($row_links = sth->fetch (PDO::FETCH_ASSOC)){
$array[$row_links['title']] = $row_links['link'];
}
then you can use
<?php foreach($array as $key => $value){ ?>
<?php echo $key; ?>
<?php } ?>

i dont want to echo the last two values in an associative array, couldn's figure it out, please help.
foreach($_POST as $key => $value){
echo $value;
}
This echoes all the values, i want to echo all but the last 2.
Just count the loops and dont print the value in the last two loops.
$i = 0;
foreach($_POST as $key => $value) {
$i++;
if($i != count($_POST) && $i != count($_POST)-1) {
echo $value;
}
}
It should work to slice the array before you loop it.
<?php
$newArray = array_slice( $_POST, 0, count($_POST)-2);
foreach( $newArray AS $key => $value ) {
echo $value;
}
If you want to keep your $key value, then set the 4th parameter to true to "preserve keys":
http://php.net/manual/en/function.array-slice.php
Maybe this is just an exercise, but I do want to note, in addition, that relying on the exact order of your POST'd elements sounds like a bad design idea that could lead to future problems.
I'd rather do this:
$a = array('a' => 'q','s' => 'w','d' => 'e','f' => 'r');
$arr_count = count($a) - 2;
$i = 1;
foreach($a as $k => $val){
echo $k.' - '.$val.PHP_EOL;
if ($i == $arr_count) break;
$i++;
}
Another alternative solution:
<?php
$tot=count($_POST)-2;
while ($tot--) {
// you can also retrieve the key using key($_POST);
echo current($_POST);
next($_POST);
}
I have problem with two arrays:
$pole1 = array(
array("klic"=>"banan", "jmeno"=>"Banán"),
array("klic"=>"pomeranc", "jmeno"=>"Pomeranč"),
);
$pole2 = array(
array("klic"=>"banan"),
);
Now I need foreach data:
foreach ($pole1 as $key => $val){
//all data from $pole
echo $val
//and here if "klic" from $pole1 == "klic" from $pole2
if ($pole2[$key]["klic"] == $pole1["klic"])
echo "YES"; // - **not working**
}
I need to check if data from $pole1 equals data from $pole2 and write some text but I need to write all data from $pole1.
You meant that?
foreach ($pole1 as $key => $val) {
if ( isset($pole2[$key]["klic"] &&
($pole2[$key]["klic"] == $pole1[$key]["klic"]) )
echo "YES";
}
try this
foreach($pole1 as $k1 => $arrays) {
foreach($arrays as $k2 => $val) {
if($pole2[$k1][$k2] == $val) {
// $pole1[$k1][$k2] is equal to $pole2[$k1][$k2]
}
}
This will echo every entry in pole1 and check every entry in pole1 with every entry in pole2.
foreach($pole1 as $val){
echo($val);
foreach($pole2 as $val2){
if($val['klic']==$val2['klic']) echo 'YES';
}
}
I have an associative array in a foreach like this:
foreach ($mArray as $aValue) {
foreach ($aValue as $key => $value) {
echo $html->find($key,$value)
}
}
It gives me this output:
bobby
johnny
Now I would like to get the last character which is y so I did:
echo substr($TheString, -1);
But this gives me: yy because its a multi-dimensional array so it gives me the last characters in each array. What can I do to get the last character on the page y (..and delete it)?
$last_char = '';
foreach ($mArray as $aValue) {
foreach ($aValue as $key => $value) {
if(substr($html->find($key,$value), -1) == 'y'){
$last_char = $html->find($key,$value);
}
}
}
echo $last_char;
This seems to work for me
echo substr_replace($TheString,"",-3);
Try This :
echo substr($TheString, -1, 1);
OR replace a string Removing y
$s="abcdey";
$m=substr($s,0,-1);
echo substr_replace($s,$m,0)
Try This :
$array = array(
"foo" => "jonny",
"bar" => "monny",
);
$i=0;
$con=count($array);
foreach($array as $key => $value)
{
$i++;
if($i==$con)
{
$s=$value;
$m=substr($value,0,-1);
$value=substr_replace($s,$m,0);
echo "Removed Y from array of last item =".$m."</br>";
}
echo $value."</br>";
}
foreach doesn't fetch end of array. I want to use end of that in another method:
$array = array(
"Language programings"=>array("php" => 100,"js" => 200),'html'=>12);
foreach ($array as $kk=>$val1)
{
echo $kk.'<br/>';
foreach ($val1 as $key=>$val2)
{
if (! end(array_keys($array)))
echo $val2;
}
echo end(array_value);//must be show 12
}
If I understand correctly, in your if() statement, you're attempting to see if the pointer is at the end of the array. Unfortunately, in this case, end() will never be false and so the line echo $val2; won't ever execute.
Try replacing
if (! end(array_keys($array)))
with
if ($key <> end(array_keys($array))
also your last line should be:
echo end(array_values($array));
Try using below code:
$array = array("Language programings"=>array("php" => 100,"js" => 200),'html'=>12);
foreach($array as $key1 => $val1){
if(is_array($val1)){
echo $key1.'<br/>';
foreach($val1 as $key2 => $val2){
if(is_array($val2)){
foreach($val2 as $k => $v){
echo $v.'<br/>';
}
} else {
echo $val2.'<br/>';
}
}
}
}
echo end(array_values($array));
The result will be:
Language programings
100
200
12
How to echo out the values individually of this array?
Array ( [0] => 20120514 [1] => My Event 3 )
so
echo $value[0]; etc
I have this so far:
foreach (json_decode($json_data_string, true) as $item) {
$eventDate = trim($item['date']);
// positive limit
$myarray = (explode(',', $eventDate, 2));
foreach ($myarray as $value) {
echo $value;
}
This echo's out the whole string no as an array. and if i do this?
echo $value[0};
Then I only get 2 characters of it??
The print_r :
Array ( [0] => 20120430 [1] => My Event 1 )
foreach ($array as $key => $val) {
echo $val;
}
Here is a simple routine for an array of primitive elements:
for ($i = 0; $i < count($mySimpleArray); $i++)
{
echo $mySimpleArray[$i] . "\n";
}
you need the set key and value in foreach loop for that:
foreach($item AS $key -> $value) {
echo $value;
}
this should do the trick :)
The problem here is in your explode statement
//$item['date'] presumably = 20120514. Do a print of this
$eventDate = trim($item['date']);
//This explodes on , but there is no , in $eventDate
//You also have a limit of 2 set in the below explode statement
$myarray = (explode(',', $eventDate, 2));
//$myarray is currently = to '20'
foreach ($myarray as $value) {
//Now you are iterating through a string
echo $value;
}
Try changing your initial $item['date'] to be 2012,04,30 if that's what you're trying to do. Otherwise I'm not entirely sure what you're trying to print.
var_dump($value)
it solved my problem, hope yours too.
