PHP - String Offset As An Array Error

Hi, when I run my script I get the following error message. These are array variables I am passing into the playerAttack function. I can't figure out what is wrong it looks fine to me. Any help greatly appreciated. Thanks. Derek


Code: [Select]
attack posted
Fatal error: Cannot use string offset as an array in C:\wamp\www\SUN_DRAGON_GAME\gamestart.php on line 202
Code: [Select]
$currentMonster='octalisk';
///////////////////////////////////////////////////////////battle////////////////////////////
//function monsterEncounter($echoMonster,$monsterImage)
  if(!empty($_POST['attack']))
{
     echo "attack posted";
playerAttack($currentMonster,$player['stats']['playerHitRollLow'],$player['stats']['playerHitRollHigh'],
$player['stats']['playerDmgLow'],$player['stats']['playerDmgHigh'],$monsters['Ocean']['octalisk']['defense'],$monster['Ocean']['octalisk']['hp'],$player['faction']['Teardrop_Ocean_Protectors']);




$doesItAttack=encounter($monsters['ocean']['octalisk']['seeInvis'],$monsters['ocean']['octalisk']['aggro'],$player['factions']['Teardrop_Ocean_Protectors']);

       
       //insert octalisk stats into monsterattack function.
     
    if($doesItAttack =='yes')
    {     
         monsterAttack($currentMonster,$monsters['Ocean']['octalisk']['hitRollLow'],$monsters['Ocean']['octalisk']['hitRollHigh'] ,
         $monsters['Ocean']['octalisk']['dmgLow'],$monsters['Ocean']['octalisk']['dmgHigh'],
         $player['stats']['playerDefense'],$player['stats']['playerHp'],$monsters['Ocean']['octalisk']['hp']);
   
    }
else
{
echo "do nothing";
}
}
here is the attack function

Code: [Select]
function playerAttack($currentMonster,$hitRollLow,$hitRollHigh,$dmgLow,$dmgHigh,$monsterDefense, $monsterHp,$playerFaction)
{     
echo "in player attack";
$playerRoll= rand($playerHitRollLow, $playerHitRollHigh);
if($playerHitRoll>=$monsterDefense)
{   
global $theMessage; //shit had to make it global

$playerDamage= rand($playerDmgLow,$playerDmgHigh);

$theMessage = "You have hit a ". $currentMonster." for "."<strong>". $playerDamage."</strong> points of damage!";
$monsterHp= $monsterHp- $playerDamage;
$theMessage.=" The ".$currentMonster."'s hp is now ".$monsterHp;
if($monsterHp<=0)
{
if($playerFaction<=0)
{
$theMessage="Your faction standing with ".$playerFaction. "could not possibly get any worse.";
}

}
$theMessage.=" You have killed the ".$currentMonster. "Your faction standing with ".$playerFaction." is now ".$playerFaction-1;

}
 
else
{
global $theMessage; //WTF i dont know what im doing.
$theMessage= " Whoa! You missed the  ".$currentMonster;
}
}

Hello, I have this script that I have been running a long time that is included in my site with a php include. It reads data from a cached file in an array. I noticed last night something has happened and it won't load in my site anymore and causes my site not to load. I determined this through various troubleshooting. Through the various troubleshooting I was able to get an error "Fatal error: Cannot use string offset as an array in /home4/mesquiu0/public_html/nws_alerts_scroller.php on line 44". This is strange because nothing has changed on my server or with this script. Also if I run it by itself it runs fine. http://www.mesquitew...ts_scroller.php but, when I include it in my site it won't load and I get the error. I am not sure what is causing this. I have done some research and it appears to be cause by a key as though it were an array of arrays. I just don't see it though.    Here is the portion of the code it is referring to. 

// IF there are alerts
if(!empty($atomAlerts)) {                                                                     // IF there are alerts
  usort($atomAlerts, 'a_sort');                                                               // sort locations
  foreach($atomAlerts as $aak => $aav) {                                                      // FOR EACH alert, get the data from the cache file
    $caav = count($aav);                                                                      // count alerts
    for($i=0;$i<$caav;$i++) {                                                                 // FOR EACH alert
      // assemble alert data
			$title[$i][0] = '<b>'.strtoupper($aav[$i][0]).'</b>';
			@$adarray[$aav[$i][10].' '.$title[$i][0]] .=  ' -  <a href="'.$alertURL.'?a='
               .$aav[$i][14].'#WA'.$aav[$i][13].'" title=" &nbsp;Details for '.$aav[$i][12]
               .' '.$aav[$i][0].'">' .$aav[$i][12] ."</a>";
    }
  }
}

Here is a sample of the cached file the script reads from. 

$atomAlerts = array (
  'TXZ104' => 
  array (
    0 => 
    array (
      0 => 'Dense Fog Advisory',
      1 => 'Expected',
      2 => 'Minor',
      3 => 'Likely',
      4 => 1418136720,
      5 => 1418148000,
      6 => 'Anderson; Bell; Bosque; Collin; Comanche; Cooke; Coryell; Dallas; Delta; Denton; Eastland; Ellis; Erath; Falls; Fannin; Freestone; Grayson; Hamilton; Henderson; Hill; Hood; Hopkins; Hunt; Jack; Johnson; Kaufman; Lamar; Lampasas; Leon; Limestone; McLennan; Milam; Mills; Montague; Navarro; Palo Pinto; Parker; Rains; Robertson; Rockwall; Somervell; Stephens; Tarrant; Van Zandt; Wise; Young',
      7 => 'DENSE FOG IS OCCURRING OVER THE REGION WHICH WILL CREATE VERY

      8 => '...DENSE FOG ADVISORY NOW IN EFFECT UNTIL NOON CST TODAY...

* IMPACTS...DENSE FOG WILL MAKE DRIVING HAZARDOUS.',
      9 => '#F60',
      10 => ' <img src="./images/FGY.gif" width="12" height="12" alt="Dense Fog Advisory" title=" Dense Fog Advisory" />',
      11 => '56',
      12 => 'Collin Co',
      13 => '1',
      14 => 'TXZ104',
      15 => '',
    ),
  ),

Any idea what might be causing this. I don't see anything right off the bat. Just strange it loads fine alone and the problem only happens and happened out of the blue when I include it in my site. I have tried to isolate it to see what might be conflicting with it but have been unsuccessful. I also would add it only errors and doesn't load when included in my site when there is an alert. Right now there is no alerts at the moment. There was alerts at the time this happened.    -Thanks

Hi,
I know the problem that I am having is related to the change in PHP5 about strings and arrays, however I do not understand why my script is affected. It seems like I am not trying to add more variables to an array. I do not success in order solve the problem.
Help me please:





// Build View Array
    if ($view_result!=false) {
        $i=0;
        while ($view_row =@ mysql_fetch_array($view_result)){
            $i++;
            $view_rows[$i] = $view_row;

            // build view_comments array
            if ($viewcomments=="yes") {
                $sql = "SELECT * FROM blog_comments WHERE nBlogId=".$view_row["nIdCode"]." ORDER BY nIdCode DESC";

                $result = mysql_query($sql,$con);
                if ($result!=false){
                    $j=0;
                    while ($comment_row =@ mysql_fetch_array($result)){
                        $j++;
                        $view_comment_rows[$i][$j] = $comment_row;
                    }
                }
            }
        }
    } else {
        $problem = "2";
    }

    // increment view counter for either the single blog being shown
    // or ALL blogs being shown
//The problem is here   
if ($view_rows[1]["nIdCode"]!="" && strpos($_SERVER["PHP_SELF"],"admin.php")==false){
        if ($viewmode=="single"){
            $blogid = $view_rows[1]["nIdCode"];
            $sql = "UPDATE blog SET nViews=nViews+1 WHERE nIdCode=".$blogid;
        } else {
            for ($i=1;$i<=count($view_rows);$i++){
                $blog_array[$i] = $view_rows[$i]["nIdCode"];
            }
            $blogids = implode(",",$blog_array);
            $sql = "UPDATE blog SET nViews=nViews+1 WHERE nIdCode IN (".$blogids.")";
        }
        $result = mysql_query($sql,$con);
        if ($result==false){
            print "<li>Problem with SQL<br>[".$sql."]</li>\n";
        }
    }
}

Earlier it was giving an error without  if (is_array($link)) {

Code: [Select]
Fatal error: Cannot use string offset as an array
However after adding it, it wont go to /hospitals-in/District-of-Columbia which is $link[1][1];

Can someone please point me my mistake

I'm getting an error: Undefined offset: 1 in… I'm trying to display a 2D array after filling it. It displays fine if I echo it while it's being made, but after it is not working.   I'm making a pyramid solitaire game and am trying to set up the pyramid of cards. There are 7 arrays, each with a set amount of cards in them. The first array only gets one cards while the last array gets seven. This makes it like a pyramid. All the indexes that don't get a card are set to 0. So it looks like this where the 1's are cards:   1 0 0 0 0 0 0 0 ​1 1 0 0 0 0 0 0 ​1 1 1 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 1 0 0 0 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1   The display2Darray function is what is causing the error. Specifically this line:

if($array[$i][$j] == 0) 

Heres my main code:

<?php
    include_once "pyramidCard.php";
    include_once "pyramidDeck.php";
    
    $theDeck = new Deck();
    $pyramid = array(array(), array(), array(), array(), array(), array(), array());
    $size = 7;

    $theDeck->shuffleCards();
    
    makePyramid($pyramid, $size, $theDeck);
    display2Darray($pyramid, $size);
    
    
    //************************
    //      FRUNCTIONS       *
    //************************
    
    function makePyramid($array, $size, $deck)
    {
        $row = 0;
        for($i = 0; $i < $size; $i++)
        {
            for($j = 0; $j < $size; $j++)
            {
                if($j > $row)
                {
                    $array[$i][$j] = 0;
                    //echo ". <br>";
                }                    
                else
                {
                    $array[$i][$j] = $deck->dealCards();
                    //echo "this card is ".$array[$i][$j]->getFace()." of ".$array[$i][$j]->getSuit()."<br>";
                }
            }
            $row++;
        }
    }
    
    
    function display2Darray($array, $size)
    {
       for($i = 0; $i < $size; $i++)
    {
        for($j = 0; $j < $size; $j++)
        {
            if($array[$i][$j] == 0)
                echo "  ";
            else
                echo $array[$i][$j]->getFace()." of ".$array[$i][$j]->getSuit();
        }
        echo "<br>";
    } 
    }
?>
