Remove the last charater from string which is generated in loop - php

Question

Believe me, I have tried everything that is there in stack overflow!
So, I got this JSON -
$j={
"itempicture": [
{
"status": "3"
},
{
"ItemCode": "001",
"ItemImage": "image1",
"ItemCategory": "shirt",
"ShowOnPOS": "Yes",
"LastModifiedOn": "2018-06-02 11:53:57"
},
{
"ItemCode": "002",
"ItemImage": "image2",
"ItemCategory": "shirt",
"ShowOnPOS": "Yes",
"LastModifiedOn": "2018-06-02 11:53:57"
}
]
}
and i am accessing it like this -
$jo = json_decode($j);
for($i = 1; $i < count($jo->itempicture); $i++) {
foreach($jo->itempicture[$i] as $prop=>$val) {
echo $val.",";
}
echo '<br>';
}
and I'm getting this output -
001,image1,shirt,Yes,2018-06-02 11:53:57,
002,image2,shirt,Yes,2018-06-02 11:53:57,
The main prob with this output is the "," at the last.
I am unable to remove it!
Tried everything -
This -
Remove the last character from string
with substr, rtrim, implode...
EVERYTHING!
It's not working!

Answer 1

A version using implode() which means that you have to convert from JSON into arrays (the default is to convert to objects, so add true as second paramter to json_decode()).
$j='{"itempicture":[
{
"status":"3"
},
{
"ItemCode":"001",
"ItemImage":"image1",
"ItemCategory":"shirt",
"ShowOnPOS":"Yes",
"LastModifiedOn":"2018-06-02 11:53:57"
},
{
"ItemCode":"002",
"ItemImage":"image2",
"ItemCategory":"shirt",
"ShowOnPOS":"Yes",
"LastModifiedOn":"2018-06-02 11:53:57"
}
]
}';
$jo=json_decode($j, true);
array_shift($jo['itempicture']);
$edata = '';
foreach ( $jo['itempicture'] as $item) {
$edata .= implode(",", $item).'<br/>';
}
echo "<pre>";
print_r($edata);
echo "</pre>";
Prints out...
<pre>001,image1,shirt,Yes,2018-06-02 11:53:57<br/>
002,image2,shirt,Yes,2018-06-02 11:53:57<br/></pre>

Answer 2

Here is the solution
$j='{"itempicture":[
{
"status":"3"
},
{
"ItemCode":"001",
"ItemImage":"image1",
"ItemCategory":"shirt",
"ShowOnPOS":"Yes",
"LastModifiedOn":"2018-06-02 11:53:57"
},
{
"ItemCode":"002",
"ItemImage":"image2",
"ItemCategory":"shirt",
"ShowOnPOS":"Yes",
"LastModifiedOn":"2018-06-02 11:53:57"
}
]
}';
$jo=json_decode($j);
$edata = '';
for($i=1;$i<count($jo->itempicture);$i++){
$data = '';
foreach($jo->itempicture[$i] as $prop=>$val){
$data .= $val.",";
}
$edata .= rtrim($data, ",");
$edata .='<br/>';
}
echo "<pre>";
print_r($edata);
echo "</pre>";

Answer 3

You could do something like this
$jo=json_decode($j);
for($i=1;$i<count($jo->itempicture);$i++){
foreach($jo->itempicture[$i] as $prop=>$val){
if ($value === end($jo->itempicture[$i])) {
echo $val;
}
else {
echo $val.",";
}
}
echo '<br>';
}
That would prevent from writing the last ',' by comparing if your current iteration is the end of the loop

Answer 4

If you know that the last element would always be LastModifiedOn
$jo=json_decode($j);
for($i=1;$i<count($jo->itempicture);$i++){
foreach($jo->itempicture[$i] as $prop=>$val){
if($prop == "LastModifiedOn")
echo $val;
else
echo $val.",";
}
echo '<br>';
}
