PHP Code Question

[f500designs]

This code takes stock information off of Yahoo! Finance's website and outputs it into text as you see below in the echo() statement. It works perfectly.

 

Now what I am trying to do is take the "Today's change" result and determine rather it is positive or negative. The "Today's change" outputs as $contents[4]

 

How do I do this? Thanks!

 

Here is my code below:

 

<?php    
$ch = curl_init();

curl_setopt( $ch, CURLOPT_URL, 'http://download.finance.yahoo.com/d/quotes.csv?s=USO&f=sl1d1t1c1ohgv&e=.csv' );
    
curl_setopt( $ch, CURLOPT_HEADER, false );
    
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

$output = curl_exec( $ch );
    
curl_close( $ch );

$contents = explode( ',', str_replace( '"', '', $output ) );

echo "US Oil Fund</p><p>Most recent trade: <b>\$$contents[1]</b></p><p>Today's Change: $contents[4]</p><p>(Prices delayed up to 20 minutes.)";
    
?>

Is this something like

<?php
if($content[4] >= 0){
  //positive
}else{
  //negative
}
?>

Or am I missing something here?

i've been trying that... tell me where i am going wrong...

 

if($content[4] >= 0){
  $status=='high';
}else{
  $status=='low';
}

[xtopolis]

You're using == instead of =

 

== -> compare

= -> assign

$status = ($content[4] >= 0) ? 'high' : 'low';

(I think)

you are genius!!!

 

Thanks so much!!

quick question to wrap things up...

 

$status will either output 'red' or 'green'... i need it to output in the middle of calling out a image file name

 

(i.e. redarrow.jpg or greenarrow.jpg)

 

what do i place in the area where there are ?????'s

 

$status = ($content[4] >= 0) ? 'green' : 'red';

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/??????arrow.jpg'>  $contents[4];

[xtopolis]

$status = ($content[4] >= 0) ? 'green' : 'red';

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  $contents[4]";

 

You may also want to change the last part, $contents[4], to ".abs($contents[4]); since you are going to be adding your own positive/negative sign.

<?php
$status = ($content[4] >= 0) ? 'green' : 'red';

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  $contents[4];
?>

 

Edit: beat me to it

[xtopolis]

We're both wrong, we both left of the s in contents for the status line, my bad.

 

$status = ($contents[4] >= 0) ? 'green' : 'red';

[f500designs]

that abs($content[4]) didn't work... but i fandangled it a bit... BUT i need it to stay two decimal places... when the number is 2.20 it changes it to 2.2

 

here's the code updated

 

$status = ($contents[4] >= 0) ? 'green' : 'red';
$abscontent = abs($contents[4]);

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  $abscontent";	

[xtopolis]

Ya, I was working on that.  I'm not sure how to carry the precision, so I cheated:

$contents = explode( ',', str_replace( '"', '', $output ) );
$status = ($contents[4] >= 0) ? 'green' : 'red';


echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  ".str_replace('-','',$contents[4]);

 

str_replace the "-" sign.

[xtopolis]

Err, found it: sprintf

 

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  ".sprintf("%01.2f", abs($contents[4]));

Err, found it: sprintf

 

echo "US Oil Fund (USO)<p>$$contents[1]  <img src='images/".$status."arrow.jpg'>  ".sprintf("%01.2f", abs($contents[4]));

 

WORKS!!!
