Hello guys,

Well, this is the first time working with arrays, what I need is to check if my array $NOHABILES in column 2 has this value "00:00:00", so I can display what I need but I'm doing something wrong.

This is the error
Warning: Cannot use a scalar value as an array in C:\inetpub\wwwroot\Intranet2014\aplicaciones\citas\calendar0115.php on line 218

<?php      
      foreach ($NOHABILES as $d => $x){
            switch ($x[1]) {
                     case 1:
                        if($NOHABILES[2] = '00:00:00') {
                              ?> <TD height="30" ALIGN=center bgcolor="#666666">1</a></TD> <?php
                        }else{
                              ?> <TD height="30" ALIGN=center bgcolor="#990000"><a href="horarios.php">1</a></TD> <?php
                        }
                  case 2:
                        if($NOHABILES[2] = '00:00:00') {
                              ?> <TD height="30" ALIGN=center bgcolor="#666666">2</a></TD> <?php
                        }else{
                              ?> <TD height="30" ALIGN=center bgcolor="#990000"><a href="horarios.php">2</a></TD> <?php
                        }
                  case 3:
                        if($NOHABILES[2] = '00:00:00') {
                              ?> <TD height="30" ALIGN=center bgcolor="#666666">3</a></TD> <?php
                        }else{
                              ?> <TD height="30" ALIGN=center bgcolor="#990000"><a href="horarios.php">3</a></TD> <?php
                        }
                        ?> </TR>
                        <TR> <?php

I don't know what is causing your main problem but this is wrong.  It is assigning a value instead of making a comparison.  A comparison is done with '==' and assignment is '='.
 // current
if($NOHABILES[2] = '00:00:00')
// should be
 if($NOHABILES[2] == '00:00:00')

$x is an element of the array $NOHABILES, but in the switch statement, you're trying to use it as an array by $x[1].

Thank you Dave & Taoyipai :)

I already change to if($NOHABILES[2] == '00:00:00') but now the error is this:
Notice: Undefined offset: 2 in C:\inetpub\wwwroot\Intranet2014\aplicaciones\citas\calendar0115.php on line 116
my array contains this:
$result = mysqli_query($mysqli,"SELECT clave, anotramite,mestramite,diatramite,horatramite,COUNT(*) FROM transacciones WHERE anotramite = '$ano' && mestramite = '$mes' GROUP BY diatramite,horatramite ORDER BY anotramite, mestramite, diatramite, horatramite");
      if ($result) {
            while($row = mysqli_fetch_array($result)) {
                  $NOHABILES[$row[0]][1] = $row["diatramite"];
                  $NOHABILES[$row[0]][2] = $row["horatramite"];
                  $NOHABILES[$row[0]][3] = $row["COUNT(*)"];
                  $totalxdia = ($row["COUNT(*)"] += "$totalxdia");

            }
            mysqli_close($mysqli);
      }
So, how to make the switch statement?

Should be something like this:
switch ($x) {
                     case 1:
                        if($NOHABILES[$d][2] == '00:00:00') {
// and the rest of your code
