I have a script that parse json files multiple times and show data in a table.
The file to be parsed is composed by a string and than a filename.json that is made of the 2 value tag you want to parse.
Ex. www.........../idr-gold.json (where idr stands for Indonesia currency).
The countries are 155 so I have ID from 1 to 155 that stands for 155 differ tags.
So what I did is a loop that every time is run add +1 to $x, so $x is inserted into a script that find the correspondence between ID and countryName and countryCurrency so that every loop run I compose the url with the missing tag for 155 times. Than the script continues parsing Json and than returns a table.
The problem are 2: 1) I would like that every line of the table is shown after file .json is parsed (so loop $x = 1, parse www.....idr-gold.json ---> returns a table line with data; than $x = 2, www......usd-gold.json and so on...). I've tried moving script parts but nothing worked.
2) The time I need to parse is really high... is a metter of my script or is cross-domain parse that is slow? it seems like I don't "close" or "empty" the script every run so that the data keep on adding making the load heavier. (About this, I've read that it might be a cross-server data transfert problem, so my solution would be the 1st problem. If I show line by line composing table and not all the table at the end of page run, I'll have a php file that will show data avery 1sec x 155 times, in spite of having a page that takes 2 mins (1sec x 155 times) before showing you anything.
So here is the code:
<body>
<?php
// var declaration (here I have ex. $italyID = 7 and $italyCurrency = itl)
include 'var-declaration/var-declaration.php';
echo "<table class='db-table' width='1000'>";
echo "<tr>
<th width='14%'>Buy Currency</th>
<th width='14%'>Sell Currency</th>
<th width='10%'>Sell Rate</th>
<th width='12%'>Sell Amount</th>
<th width='15%'>Seller Name</th>
<th width='35%'>Link to Page</th>
</tr>";
// LOOP da 0 a 155
$x = 0;
do{
// TEST echo "The number is: $x <br>";
$iscountryID = ("$country".$x."");
$currencyVarName = "";
if ($iscountryID == 0) {
$currencyVarName = $goldCurrency;
} elseif ($iscountryID == 1) {
$currencyVarName = $polandCurrency;
} elseif ($iscountryID == 2) {
$currencyVarName = $russiaCurrency;
} elseif ($iscountryID == 3) {
$currencyVarName = $germanyCurrency;
} elseif ($iscountryID == 4) {
$currencyVarName = $franceCurrency;
} elseif ($iscountryID == 5) {
$currencyVarName = $spainCurrency;
} elseif ($iscountryID == 6) {
$currencyVarName = $unitedKingdomCurrency;
} elseif ($iscountryID == 7) {
$currencyVarName = $italyCurrency;
... (up to 155)
} elseif ($iscountryID == 154) {
$currencyVarName = $bahrainCurrency;
} elseif ($iscountryID == 155) {
$currencyVarName = $kwaitCurrency;
};
// if Currency name it isn't null
if ($currencyVarName != NULL) {
$urlLoopBuy = strtolower("....exchange/".$currencyVarName."-gold.json");
$jsonLoopBuy = file_get_contents($urlLoopBuy);
$outLoopBuy = json_decode($jsonLoopBuy, true);
//json data parse
$buycurrency = $outLoopBuy['buy']['currency'];
$sellcurrency = $outLoopBuy['sell']['currency'];
$sellrate = $outLoopBuy['offer'][0]['rate'];
$sellamount = $outLoopBuy['offer'][0]['amount'];
$sellername = $outLoopBuy['offer'][0]['seller']['name'];
// table content
echo "<table class='db-table' width='1000'>";
echo "<tr>
<td width='14%'>".$buycurrency."</td>
<td width='14%'>".$sellcurrency."</td>
<td width='10%'>".$sellrate."</td>
<td width='12%'>".$sellamount."</td>
<td width='15%'>".$sellername."</td>
<td width='35%'>".$urlLoopBuy."</td>
</tr></table>";
} else { // if currency name is NULL
$buycurrency = "record problem";
$sellcurrency = "record problem";
$sellrate = "record problem";
$sellamount = "record problem";
$sellername = "record problem";
//add +1 to loop
$x++;
};
} while ($x <= 155);
// Link to Page
$linktopage = "...monetarymarket.html?buyerCurrencyId=".$buyercountryID."&sellerCurrencyId=".$sellercountryID."";
?>
</body>
That's it. Thanks.
