  1. POHow to get an array value after explode?
    text
    copied!<p>I have passed a value from one page to another in array. I can extract first two vars by explode but I can't get the third value which is formed in an array out.</p> <p>This is my array:</p> <pre><code>$user_rate=$_POST['user_rate'];//15000|ss|Array list($total,$promo,$rate)=explode("|",$user_rate); </code></pre> <p>So I get:</p> <pre><code>$total=15000; $promo=ss; $rate=Array; </code></pre> <p>While Array comes from the previous page by looping the daily rate and put in an array. And I need to know what each rate is, so I wrote:</p> <pre><code>foreach($rate as $val){ echo "$val&lt;br&gt;"; } </code></pre> <p>But it shows nothing. How can I get this?</p> <p>Updated : This is the code before the var is sent.</p> <pre><code>echo " &lt;tr&gt; &lt;td align=\"right\" colspan=\"3\"&gt;Total&lt;/td&gt; &lt;td align=\"right\"&gt;&lt;label for=\"promo_3\"&gt;&lt;input type=\"radio\" name=\"user_rate\" id=\"promo_3\" value=\"$ss_total|ss|$cost_ss\" /&gt;&amp;nbsp;&lt;u&gt;&lt;b&gt;".number_format($ss_total)."&lt;/b&gt;&lt;/u&gt;&lt;/label&gt;&lt;/td&gt; &lt;td align=\"right\"&gt;&lt;label for=\"promo_1\"&gt;&lt;input type=\"radio\" name=\"user_rate\" id=\"promo_1\" value=\"$net_total|nc|$cost_nr\" checked/&gt;&amp;nbsp;&lt;u&gt;&lt;b&gt;".number_format($net_total)."&lt;/b&gt;&lt;/u&gt;&lt;/label&gt;&lt;/td&gt; &lt;/tr&gt;"; </code></pre> <p><strong>AND THIS FORMAT OF VALUE CANNOT CHANGE BECAUSE I NEED IT FOR A LATER JAVASCRIPT EXTRACT</strong></p> <p>While <strong>$cost_ss</strong> and <strong>$cost_nr</strong> are derived from database query looping.</p> <pre><code>while($rec=mysql_fetch_array($result)){ $cost_ss[]=$rec['rate_ss']; $cost_nr[]=$rec['rate_nr']; } </code></pre>
