i have these row in table
K04, K84, K53, K331, L985
how i can do with array explode to get result like :
['K04','K84','K53','K331','L985']
thanks for any help...
i tried to using explode,
$ex = explode (' ,' $myRowFromTable)
$co = count ($ex);
for ($i = 0; $i < $co; $i++)
{
echo $ex[$i];
}
result only show K04
Seems like you want to convert String to JavaScript Array. Take a look for Example;
$myRowFromTable = 'K04, K84, K53, K331, L985';
// Has Array Data
$ex = explode (', ', $myRowFromTable);
// print_r($ex);
// According to User Expected Result
$newFormat = "['" . implode("', '", $ex) . "']";
echo $newFormat;
DEMO
You should try using explode as below assuming you are getting the values as a string in $myRowFromTable:
$ex = explode (',', $myRowFromTable); //no space before comma

I have probably information about whether it is available in PHP to detect a duplicate and a book about not removing it and adding it to -1, -2, -3
Example:
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
Result:
$output = 'H4,H4-1,H3,WY21W,W5W,W5W-1,WY21W-1,W21/5W,W21/5W-1,W21W,W16W,W5W-2'
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
$parts = explode(',', $string); // split by comma
$used = []; // array to count the number of occurrences
$result = []; // array to take the "new" elements
foreach($parts as $part) {
if(isset($used[$part])) { // if there is an entry in the counter array already,
// increment it by one,
$used[$part]++;
}
else { // else initialize with 0
$used[$part] = 0;
}
// put part into new array, append -(counter) if counter > 0
$result[] = $part . ($used[$part] ? '-'.$used[$part] : '');
}
echo implode(',', $result); // join together with comma
Pretty much the same as misorude's answer.
<?php
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
$values = explode(',', $string);
foreach($values as $k => $value)
if($counts[$value] = !isset($counts[$value]) ? 0 : $counts[$value]-1)
$values[$k] = $value . $counts[$value];
print implode(',', $values);
Output:
H4,H4-1,H3,WY21W,W5W,W5W-1,WY21W-1,W21/5W,W21/5W-1,W21W,W16W,W5W-2

I am facing a problem.
My table contain a field named 'tags'.
This field have comma separated values.
For ex: Hello, start, good & another one is: Time, Goal, Lucky, start.
Now my problem is that, I want to send each comma separated values in json array
and none of them should repeat itself.
My array should be like this:
{
"tag":[
"Hello",
"start",
"good",
"Time",
"Goal",
"Lucky"
]
}
Just do this with your code.
Assuming $tag_string has the comma separated data.
<?php
$tag_string= "Hello, start, good, Time, Goal, Lucky, start";
$val['tag'] = explode(",", $tag_string);
$val['tag'] = array_unique($val['tag']);
echo json_encode($val);
?>
As you asked in comment answer::
<?php
$tag_string = "Hello, start, good, Time, Goal, Lucky, start";
$val = explode(",", $tag_string);
$val_count = count($val);$html = "[ ";$counter = 1;$data_validate = [];
foreach ($val as $val_row)
{
if (!in_array($val_row, $data_validate))
{
$data_validate[] = $val_row;
$html .= '{"tag":"' . $val_row . '"}';
$html .= $counter < $val_count-1 ? ',' : '';
}
$counter ++;
}
$html .= " ]";
echo $html;
?>
Use a regexp to make à php array then just use jdon_encode() on your array.
You can also use php explose() function to make your php array.
use json_encode(explode(', ', "Hello", "start", "good", "Time", "Goal", "Lucky"));
if you don't have space in your string.
split String using delimiter "," using explode() and remove duplicate value array_unique.
$your_str = "Hello,start,good,Time,Goal,Lucky"
$res["tag"] = array_unique(explode(",", $your_str));
print_r(json_encode($res));
<?php
$tag_string= "Hello, start, good, Time, Goal, Lucky, start";
$result = [];
$result['tag'] = array_unique(preg_split('/\s*,\s*/', $tag_string, NULL, PREG_SPLIT_NO_EMPTY));
echo json_encode($result);

i can separate join column with comma, but how to remove comma if on the second column is null?
in below, i have 2 column i want join otot2 and otot3
1. how to not shown comma after otot2 if otot3 null?
2. and how to not shown anything comma if otot2 and otot 3 null?
3. otot2 and otot3 flexible ( not always has data)
here my php code for output query:
if(mysqli_num_rows($hasil) > 0)
{
$response = array();
while($data = mysqli_fetch_array($hasil))
{
$h['main muscle'] = $data['otot1'];
$h['other muscle'] = $data['otot2'].', '.$data['otot3'];
array_push($response, $h);
}
$response["success"];
echo json_encode($response);
A simple solution would be -
$response = array();
while($data = mysqli_fetch_array($hasil))
{
// other code
$temp = array($data['otot2'], $data['otot3']); // Store them in array
$temp = array_filter($temp); // remove empty values
$h['other muscle'] = implode(',', $temp); // implode them with (,)
// Other codes
array_push($response, $h);
}
By using array_filter & implode you don't have to worry about the ,, as array_filter would remove the empty values and if there is 2 values in the array them the string would be , separated else not.
Or you can try this also
$h['other muscle'] = $data['otot2'];
if($data['otot3'] !== null)
$h['other muscle'] .= ', ' . $data['otot3']; // Concatenate

I want to retrieve comma separated values from a database and store each value in a variable.
For example: in my column I have the following: 2,3,5,8,9,21
I'd like to store the numbers inside variables like this:
$a=2
$b=3
$c=5
// and so on…
If you wanna load the string that contain integers separated with ',' or '.' or 'a' or ';' do:
If you wanna go for ',':
$char = ',';
If you wanna go for '.':
$char = '.';
If you wanna go for 'a':
$char = 'a';
If you wanna go for ';':
$char = ';';
(I added this to help anyone that have any other syntax of string)
To connect you can do(Documentation):
$connection = mysql_connect('adress', 'mysql_user', 'mysql_password');
Okay, we have connection. Now take the data (Documentation).
$database = "DatabaseWithTableWithIntegers";
$table = "TableWithIntegers";
$rowname = "RowWithIntegers";
$sql = "USE $database; SELECT $rowname FROM $table;";
$result = mysql_query ($sql, $connection);
Now declare something like list:
$arr = []; // array for fetching
$vrr = []; // array for fetched
Next step is to fetch rows(Documentation):
while($row = mysql_fetch_row($result)){
Row have string like "2,142,124,53,3511,513,531,53" if separator was an "," and the record exists in database/table.
The magical function is explode, it slices all the segments into an array(Documentation):
$arr = explode($char, $row[$rowname]); //rowname is to be 100% sure
The last thing is to do the conversion(Documentation)
for($arr as &$a){
$value = intval($a);
array_push($vrr, $value); // to save the value into vrr([Documentation][6])
}}
have a look on below solutions:
Method 1
$alphabet = range('a', 'z');
$str = '2,3,5,8,9,21';
$str_array = explode(',', $str);
foreach($str_array as $k=>$v){
${$alphabet[$k]} = $v;
}
echo $a,$b,$c,$d;
Method 2
$var = 'a';
$str = '2,3,5,8,9,21';
$str_array = explode(',', $str);
foreach($str_array as $k=>$v){
${$var} = $v;
++$var;
}
echo $a,$b,$c,$d;
both solution's output:
2358
if you are storing data in form of a1,a2,a3 in a single column, why don't you just fetch the data and split it using explode() method?
if you are using associative array, then use json_encode() when storing the data as string, and then decode it using json_decode() after fetched from database

I found problem with this:
$explode = explode($start, $data);
$abc = explode($end, $explode[1]);
$found = $abc[0] . '<br/>';
$found .= $abc[1] . '<br/>';
$found .= $abc[2] . '<br/>';
return $found;
The abc[0], abc[1] and more is randomly based by exploded results. How to define if $found is array or something I can loop it in foreach?
That's. Thank You for answer.
explode($start, $data) will return an array unless $start is an empty string "" in which case it will return false. You can confirm whether $found is an array by using is_array($found) which will return true if $found is an array and false otherwise.
