    Change font with IF

    Hey guys. I was wondering if its possible to change font color based on text.

    Im grabbing stock symbols with change
    i want it so if the change is negative its red and positive green

    how can this be accomplished?

    Code:
    <body bgcolor="#1C2F2F">
    <?php
    
      //Obtain Quote Info
      $quote = file_get_contents('http://finance.google.com/finance/info?client=ig&q=NASDAC:' . $stock . '');
    
      //Remove CR's from ouput - make it one line
        $json = str_replace("\n", "", $quote);
    
      //Remove //, [ and ] to build qualified string  
        $data = substr($json, 4, strlen($json) -5);
    
      //decode JSON data
        $json_output = json_decode(utf8_decode($data));
    
      // get the last price
        $perc = $json_output->cp;
        $last = $json_output->l;
        $date = $json_output->lt;
        $name = $json_output->t;
    
      //Output Stock price .
      echo 'Stock Symbol: ' . $name;
      echo '<br />';
      echo 'Last Price: ' . $last; 
      echo '<br />';
      echo 'Change: ' . $perc;
      echo 'Date: ' . $date;
    
    
    ?>
    
    <font color="#0099FF">
    <form method="post">
    <input type="text" name="myInput" id="myInput">
    <input type="submit" name="submit" value="Submit">
    </form>
    
    
    <br /><br />
    <font color="#ff0000">
    <u>
    <?php
    echo "$wod1";
    ?>
    
    <b>:</b></font></u><font color="#fff">
    <?php
    echo "$wod2";
    ?></font>
    New to PHP and MySql. Started looking at scripts about a week ago. So far have very little understanding of it. So please be easy with me if I ask a stupid question.

    Re: Change font with IF

    Use strpos() to search for the "-". Then change the CSS accordingly.
