comparison between two string variables

[rachid]

Hi,<br><br>Could help me to solve the following problem:<br><br>A numerical variable is sent from an &lt;input&gt; tag to a WML &lt;card&gt;. The value's type is string (checked by the PHP function gettype() ). When trying to compare it to another string variable which comes from a MySQL databases, there is no effect.<br>The second problem is when trying to convert the first variable to a double. The return value is always zero.<br><br><br>thanks in advance,<br>R. kaced<br><A HREF="mailto:rachid@rosebud.fr">rachid@rosebud.fr</A><br><br>

Can you write the exact syntax you are using?

This is the syntax:<br><br>----------------------------------------------------<br><br>function stocker1($respSocHV,$tMin) { <br>$k = 0;&nbsp;&nbsp;//'$k' sert à indexer tous les 'last_closing_price' non nuls et ayant un taux &gt; $tMin<br>//Création de deux vecteurs-réponses puisque la requête réclame deux colonnes <br>while ( list($Name,$taux) = mysql_fetch_row($respSocHV) ) {<br>//Selection des taux supérieurs à '$tMin'<br>&nbsp;&nbsp;&nbsp;&nbsp;if ( $taux &gt; $tMin ) {&nbsp;&nbsp; $tauxS[$k] = $taux;&nbsp;&nbsp;<br> $vectNameS[$k] = $Name;<br>&nbsp;&nbsp;&nbsp;&nbsp;} else { <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo(&quot;&lt;p&gt;Essayer un taux plus bas&lt;br/&gt;&lt;/p&gt;&quot; }<br>&nbsp;&nbsp;&nbsp;&nbsp;$k++; <br>}<br>return array($vectNameS,$tauxS);<br>}<br><br>-----------------------------------------------------<br><br>echo(&quot;&lt;card&nbsp;&nbsp;id=\&quot;card011\&quot;&nbsp;&nbsp;title=\&quot;Taux minimal\&quot;&gt;<br> &lt;do&nbsp;&nbsp;type=\&quot;accept\&quot;&nbsp;&nbsp;label=\&quot;Les réponses\&quot;&gt; <br> &lt;go&nbsp;&nbsp;href=\&quot;#card0111\&quot;&nbsp;&nbsp;method=\&quot;post\&quot;&nbsp;&nbsp;/&gt;<br> &lt;/do&gt; <br> &lt;p align=\&quot;left\&quot;&gt;<br> Introduire un taux de variations minimal: <br> &lt;input&nbsp;&nbsp;name=\&quot;t\&quot;&nbsp;&nbsp;&nbsp;format=\&quot;*N\&quot; /&gt; <br> &lt;/p&gt;&lt;/card&gt;&quot;<br><br>------------------------------------------------<br><br>echo(&quot;&lt;card&nbsp;&nbsp;id=\&quot;card0111\&quot;&nbsp;&nbsp;title=\&quot;Tri par taux\&quot; &gt;&quot;<br>list($vectNameS,$tauxS) = stocker1($respSocHV,&quot;$(t)&quot;<br>.<br>.<br>.<br>echo(&quot;&lt;/card&gt;&quot;<br><br>-----------------------------------------------<br><br>The problem is when comparing each element $taux with $tMin<br>with the if statement. It does anything but the execution of the script goes inside the if statement.<br><br>Thank you very much for trying<br>Rachid<br>
