Warning: in_array() [function.in-array]: Wrong datatype for second argument

[alapimba]

Hello

 

I'm using tcpdf to convert some stuff to pdf.

On my local computer running wamp my script works perfect and the pdf is generated without problems

When i put my files in a webserver i got this error:

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/vieira/public_html/topdf/dbcon.class.php on line 68

 

Line 68 is:

if(in_array($key,$arr_switches)){  //check switches

 

My complete code is:

 

    // Get fields of enum on/off switches type
    $result2 = mysql_query("SHOW FIELDS FROM $db_name.$table");
    $counter=0;    
    while($row = @mysql_fetch_array($result2)){
        //echo $row['Field'] . ' ' . $row['Type']."<br/>";
        if($row['Type'] === "enum('on','off')"){
            $arr_switches[$counter] = $row['Field'];
            $counter++;
        }        
    }
    //print"<pre>"; print_r($arr_switches); print"</pre>";exit;
    
    $counter = 0;
    while($row = @mysql_fetch_array($result)){
        foreach( $row as $key => $val ){
            if(!is_numeric($key))
            {
                $row_rs_certidao[$key] = $val;
                if(in_array($key,$arr_switches)){   //check switches
                    $record_key[$counter] = htmlentities('<?php if (!(strcmp($row_rs_certidao['."'".$key."'".'],"on"))) {echo "x";} ?>');
                    if($val==='on') $record_val[$counter] = "x";    //turn on switches
                    else $record_val[$counter] = '';                //turn off
                }else{
                    $record_key[$counter] = htmlentities('<?php echo $row_rs_certidao['."'".$key."'".']; ?>');
                    $record_val[$counter] = htmlentities($val);
                }
                $counter++;                
            }            
        }        
    }

 

Anyone can help?

don't do this:

 

@mysql_fetch_array($result2)

 

remove the @ and erase it from your memory. don't use it anywhere.

 

Also, it is really super-helpful to know if your query fails. update your code to this:

 

$result2 = mysql_query("SHOW FIELDS FROM $db_name.$table") or die(mysql_error());

 

i suspect that $arr_switches is not an array, and that's why you get that error. i would initialize the array before performing the first mysql_query.

 

$arr_switches = array();

You also might want run a file comparison app on your php.ini files (local and server) to determine the version and setting differences...
