I have a variable on my page called, $recipe['ingredients'];
inside the var you have as follows,
100ml milk, 350ml double cream, 150ml water
and so on. Now I'm trying to split it up so it looks as follows
<ul>
<li>100ml milk</li>
<li>350ml double cream</li>
<li>150ml water</li>
</ul>
So far I have the following code,
$ingredientsParts = explode(',', $row_rs_recipes['ingredients']);
$ingredients = array($ingredientsParts);
while (! $ingredients) {
echo" <li>$ingredients</li>";
}
But for some reason it doesn't work and I do not have the experience with explode to fix it.
$ingredientsParts = explode(',', $row_rs_recipes['ingredients']);
$li = '<ul>';
foreach($ingredientsParts as $key=>$value){
$li.=" <li>$value</li>";
}
$li.= '</ul>';
echo $li;
this should be enough:
$ingredientsParts = explode(', ', $row_rs_recipes['ingredients']);
foreach ($ingredientsParts as $ingredient)
{
echo "<li>$ingredient</li>";
}
or you can explode it by ',' and use echo '<li>' . trim($ingredient) . '</li>'; to remove whitespace from beginning/end of that string
When you explode() a string it is automatically converted into an array. You do not need to convert it to an array type as you did on the second line.
You want to use a foreach() loop to iterate through an array, not a while loop.
$ingredientsAry = explode(',', $row_rs_recipes['ingredients']);
foreach($ingredientsAry as $ingredient){
echo "<li>$ingredient</li>";
}
In fact you can just do a foreach() loop on the explode() value
foreach(explode(',', $row_rs_recipes['ingredients']) as $ingredient){
echo "<li>$ingredient</li>";
}
The explode method already return an array, so you don't have to transform your variable $ingredientsParts into an array.
Just do:
$ingredientsParts = explode(', ', $row_rs_recipes['ingredients']);
foreach ($ingredientsParts as $ingredient)
{
echo "<li>$ingredient</li>";
}
if (!empty($recipe['ingredients'])) {
echo '<ul><li>' . implode('</li><li>', explode(', ', $row_rs_recipes['ingredients'])) . '</li></ul>';
}
You can do this:
$ingredients = explode(',', $row_rs_recipes['ingredients']);
$list = '<ul>';
foreach ($ingredients as $ingredient)
{
$list .= '<li>' . $ingredient . '</li>';
}
$list .= '</ul>';
echo $list;

I have a string:
works/but/needs/splitting
I'd need the output in a ul list
<ul>
<li>works</ul>
<li>but</li>
<li>needs</li>
<li>splitting</li>
<ul>
I have been looking into explode("/", $text); and tried
$originalstring = "works/but/needs/splitting";
$delimiter = "/";
if(strpos($originalstring,$delimiter) > 0){
But I just don't know much of php and I can't work it out
Sorry I might not understand your questions, But split by / is this
$originalstring = "works/but/needs/splitting";
$pieces = explode("/", $originalstring);
echo '<ul>';
foreach ($pieces as $pi){
echo '<li>'.$pi.'</li>';
}
echo '</ul>';
$originalstring = "works/but/needs/splitting";
$e=explode('/',$originalstring); //creates the array ($e) of each element
echo '<ul>';
foreach ($e as $each){ //loop the array ($e)
echo '<li>'.$each.'</li>';
}
echo '</ul>';
The title may be a bit misleading, to be honest I don't know what this feature is called.
I have a field which will contain a list of a users skills in the database, the skills will be separated by commas.
When I then echo the field, I want each skill after the commas to be in a new list element.
So it'll echo like this in the HTML:
<ul>
<li>Cycling</li>
<li>Driving</li>
<li>Running</li>
</ul>
However in the field 'skills' it'll look like:
Cycling, Driving, Running
I read that you need to explode the comma however I have no idea how to accomplish it.
Here's explode:
$activities = explode(',', $activities);
Filter to trim the values of the array (so there's no whitespace on them) using array_map:
$activities = array_map('trim', $activities);
Then glue it back up with implode:
$activities = '<li>' . implode('</li><li>' . $activities) . '</li>';
Put it all together, with a bit of defensive programming:
$activities = explode(',', $activities);
if ( $activities ) {
$activities = array_map('trim', $activities);
$activities = '<li>' . implode('</li><li>' . $activities) . '</li>';
}
You could use str_replace:
$skills = "Cycling, Driving, Running";
echo '<ul><li>' . str_replace(", ", "</li><li>", $skills) . '</li></ul>';
This can be achieved with explode (php documentation).
$activities = 'Cycling, Driving, Running';
$exploded = explode(', ', $activities);
foreach ($exploded as $activity) {
echo '<li>' . $activity . '</li>';
}
$list = "Cycling, Driving, Running";
$elements = explode(", ",$list);
echo "<ul>";
foreach($elements as $element){
echo "<li>$element</li>";
}
echo "</ul>";
I've got it working now! :)
Thanks to who contributed.
Code I used:
<ul class="list-unstyled">
<?php
$activities_q = "SELECT skills FROM users WHERE uid='".$row['uid']."'";
$activities = $row['skills'];
$exploded = explode(',', $activities);
foreach ($exploded as $activity) {
echo '<li class="list-group-item">' . $activity . '</li>';
}
?>
</ul>
I have a set of numbers in a table field in database, the numbers are separated by comma ','.
I am trying to do the following:
Step 1. : SELECT set of numbers from database and explode it to array :
$array = explode(',', $set_of_numbers);
Step 2. : Print each element of the array as list item by using foreach loop :
foreach ($array as $list_item => $set_of_numbers){
echo "<li>";
print_r(array_list_items($set_of_numbers));
echo "</li>";}
Please anybody tell me what is wrong. Thank you.
$numbers = '1,2,3';
$array = explode(',', $numbers);
foreach ($array as $item) {
echo "<li>$item</li>";
}
Assuming your original $set_of_numbers is simply a CSV string, something like 1,2,3,4,..., then your foreach is "mostly" ok. But your variable naming is quite bonkers, and your print-r() call uncesary:
$array = explode(',', $set_of_numbers);
foreach($array as $key => $value) {
echo "<li>$key: $value</li>";
}
Assuming that 1,2,3,4... string, you'd get
<li>0: 1</li>
<li>1: 2</li>
<li>2: 3</li>
etc...
$numbers = "1,2,3";
$array = explode(",", $numbers);
/* count length of array */
$arrlength = count($array);
/* using for while */
$x = 0;
while ($x < $arrlength) {
echo "<li>$array[$x]</li>" . PHP_EOL;
$x++;
}
echo PHP_EOL;
/* using for classic */
for ($x = 0; $x < $arrlength; $x++) {
echo "<li>$array[$x]</li>" . PHP_EOL;
}
echo PHP_EOL;
/* using for each assoc */
foreach ($array as $value) {
echo "<li>$value</li>" . PHP_EOL;
}
echo PHP_EOL;
/* using for each assoc key */
foreach ($array as $key => $value) {
echo "<li>$key => $value</li>" . PHP_EOL;

You actually don't need to explode on the commas. You can just replace each comma with an ending tag followed by an opening tag and then wrap your whole string in an opening and closing tag.
$set_of_numbers = '1,2,3';
echo '<li>' . str_replace(',', '</li><li>', $set_of_numbers) . '</li>';
// outputs: <li>1</li><li>2</li><li>3</li>
No looping is necessary.
Here is answer for your question to get ride of your problem
$Num = '1,2,3,4,5,';
$Array = explode(',',$Num);
foreach ($Array as $Items)
{
echo "<li>&Items</li>"; // This line put put put in the list.
}
This can easily be achieved by the following code snippet:
<?php
$my_numbers = '1,12,3.2,853.3,4545,221';
echo '<ul>';
foreach(explode(',', $my_numbers) AS $my_number){
echo '<li>'.$my_number.'</li>';
}
echo '</ul>';
The above code will output the following HTML:
<ul><li>1</li><li>12</li><li>3.2</li><li>853.3</li><li>4545</li><li>221</li></ul>

I have a field in my database with the text value:
"these, are, some, keywords" (minus the inverted commas)
Now, I wonder if I can generate an unordered list from this so ultimately my HTML reads:
<ul>
<li>these</li>
<li>are</li>
<li>some</li>
<li>keywords</li>
</ul>
Is this possible with PHP and if so is anyone able to help me out with this?
Many thanks for any pointers.
You can accomplish this with something like the following:
<?php
$yourList = "these, are, some, keywords";
$words = explode(',', $yourList);
if(!empty($words)){
echo '<ul>';
foreach($words as $word){
echo '<li>'.htmlspecialchars($word).'</li>';
}
echo '</ul>';
}
?>
As mentioned by elcodedocle, you may want to use str_getcsv() instead of explode if more appropriate.
Have a look at str_getcsv() and explode()
Example:
<?php
$mystring = "these, are,some , keywords";
$myvalues = str_getcsv($mystring);
$myoutput = "<ul>";
foreach ($myvalues as $value){
$myoutput .= "<li>".trim($value)."</li>\n";
}
$myoutput .= "</ul>";
echo $myoutput;
?>
You need to explode you string for ', '
print <ul>
for each element in the array you received you print '<li>' . $value . '</li>'
print </ul>
You can try:
$arr = explode(",","these, are, some, keywords");
$res = "<ul>";
foreach ($arr as $val){
$res .= "<li>" . $val . "</li>";
}
$res .= "</ul>";
echo $res;
here is my working php explode code for NON links:
<?php
$textarea = get_custom_field('my_custom_output');
$array = explode(',',$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
$item = trim($item); // clear off white-space
$output .= '<li>' . $item . '</li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
..and the code which defines "my_custom_output", which I input into my textarea field:
text1,text2,text3,etc
..and the finished product:
text1
text2
text3
etc
So that works.
Now what I want to do is make text1 be a link to mywebsite.com/text1-page-url/
I was able to get this far:
<?php
$textarea = get_custom_field('my_custom_output');
$array = explode(',',$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
$item = trim($item); // clear off white-space
$output .= '<li class="link-class"><a title="' . $item . '" href="http://mywebsite.com/' . $item_links . '">' . $item . '</a></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
Now, I would like $item_links to define just the rest of the url. For example:
I want to put input this into my textarea:
text1:text1-page-url,text2:new-text2-page,text3:different-page-text3
and have the output be this:
text1
text2
..etc (stackoverflow forced me to only have two links in this post because I only have 0 reputation)
another thing I want to do is change commas to new lines. I know the code for a new line is \n but I do not know how to swap it out. That way I can put this:
text1:text1-page-url
text2:new-text2-page
text3:different-page-text3
I hope I made this easy for you to understand. I am almost there, I am just stuck. Please help. Thank you!
Just split the $item inside your loop with explode():
<?php
$separator1 = "\n";
$separator2 = ":";
$textarea = get_custom_field('my_custom_output');
$array = explode($separator1,$textarea);
$output = ''; // initialize the variable
foreach ($array as $item) {
list($item_text, $item_links) = explode($separator2, trim($item));
$output .= '<li class="link-class"><a title="' . $item_text . '" href="http://mywebsite.com/' . $item_links . '">' . $item_text . '</a></li>';
}
?>
<ul>
<?php print $output; ?>
</ul>
And choose your string separators so $item_text, $item_links wouldn't contain them.
After you explode the string you could loop through again and separate the text and link into key/values. Something like...
$array_final = new array();
$array_temp = explode(',', $textarea);
foreach($array_temp as $item) {
list($text, $link) = explode(':', $item);
$array_final[$text] = $link;
}
foreach($array_final as $key => $value) {
echo '<li>'.$key.'</li>';
}
to change comma into new line you can use str_replace like
str_replace(",", "\r\n", $output)
