IF ELSEIF fo array inside While loop PHP
Question
I've get the value inside literal tag in this xml:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="/xml-to-html.xsl"?>
<sparql xmlns="http://www.w3.org/2005/sparql-results#">
<head>
<variable name="Kategori"/>
</head>
<results>
<result>
<binding name="Kategori">
<literal datatype="http://www.w3.org/2001/XMLSchema#string">Gerak Kasar</literal>
</binding>
</result>
<result>
<binding name="Kategori">
<literal datatype="http://www.w3.org/2001/XMLSchema#string">Gerak Halus</literal>
</binding>
</result>
</results>
</sparql>
using this code:
$x = 0;
$kategori = array();
while ($x < count($hasilcek->results->result)) {
$kategori[$x]= $hasilcek->results->result[$x]->binding->literal;
$x++; }
But when I try to get the result by IF ELSEIF inside WHILE using this code:
$x = $x-1;
while ($x > -1){
if ($kategori[$x] = 'Gerak Kasar') {echo "Gerak Kasar";}
elseif ($kategori[$x] = 'Gerak Halus') {echo "Gerak Halus";}
else {echo "tidak ada";}
$x--;}
exactly the result should be:
Gerak Kasar Gerak Halus
but why i get :
Gerak KasarGerak Kasar
I think there is something wrong when I do IF selection for $kategori[] inside the WHILE. Can anyone explain? Thanks.

instead of comparison operator your are using assignment operator.
if ($kategori[$x] = 'Gerak Kasar') {echo "Gerak Kasar";}
elseif ($kategori[$x] = 'Gerak Halus') {echo "Gerak Halus";}
So change it to
if ($kategori[$x] == 'Gerak Kasar') {echo "Gerak Kasar";}
elseif ($kategori[$x] == 'Gerak Halus') {echo "Gerak Halus";}
Because when if ($kategori[$x] = 'Gerak Kasar') is executed $kategori[$x] become Gerak Kasar always. That is why you get the same result again.

Selamat Pagi. :)
Try this :
$x = $x-1;
while ($x > -1){
if ($kategori[$x] == 'Gerak Kasar') {echo " Gerak Kasar ";}
elseif ($kategori[$x] == 'Gerak Halus') {echo " Gerak Halus ";}
else {echo "tidak ada";}
$x--;}
