PHP - Using An Offset
I need the following format for dat and time:
date("Y-m-d H:i:s"); Now, I know the time offset and want to adjust the above. Let's say the GMT time offset is 1. How do I adjust it using the code above? I tried as an example date("Y-m-d H:i:s",3600); but that adjusted the time by 8 hours! Similar Tutorialshey guys im in a bit trouble trying to use window offset() function.
basically i have a fixed header and what im trying to accomplish is for when the user scroll past a certain point the header content will change...im not sure if im going about this the right way or even sure if it is possible with a fixed header.
any help would be grateful thank you

hi... i'm getting an undefined offset for the associative arrays [28-46] in this format. $sql="INSERT INTO tableName (name1, name2, name3, name4... this goes all the way to name46) VALUES ('".$data[0]."', '".$data[1]."', '".$data[2]."', '".$data[3]."' ...this goes all the way to name46)"; $sqlData = mysql_query($sql); i have read that i can prevent the notices by doing the following, but it's not working for me: $sql="INSERT INTO tableName ( 'name1' => "isset(.$data[0].) ? $data[0] : 'default value'", 'name2' => "isset(.$data[1].) ? $data[1] : 'default value'", 'name3' => "isset(.$data[2].) ? $data[2] : 'default value'", 'name4' => "isset(.$data[3].) ? $data[3] : 'default value'", #this goes all the way to name46 )"; $sqlData = mysql_query($sql); can anyone please assist me? instead of js alert displaying the timezone offset, i would like the content of get_time_zone_offset() to be used as a php variable.
<script type="text/javascript">
function get_time_zone_offset( ) {
var current_date = new Date();
return -current_date.getTimezoneOffset() / 60;
}
alert("The local time zone is: GMT " + get_time_zone_offset());
</script>
Hello, my script worked great with no errors until I had to migrate to a new server, which is using cpanel/WHM, I have run Apache update and ensured curl is installed but I keep getting this in the error log. Here is part of the code, the error is PHP Notice: Undefined offset: 2 in /home/username/public_html/control/ajax/actions/currently_playing.php on line 59 and here is that section of code (line 59 is labled) Code: [Select] // Diaplays when sever is online but no song title } else { $title = str_replace('\'', '`', $split[6]); $title = str_replace(',', ' ', $title); $title = "$title"; // Diaplays song } } if($title) { $tmp = explode(" - ", $title); $artist = trim(str_replace("`", "'", $tmp[0])); $album = trim(str_replace("`", "'", $tmp[1])); $title = trim(str_replace("`", "'", $tmp[2])); //LINE 59 HERE $request = $this->albumGetInfo($artist, $album); $img = $request["album"]["image"][1]["#text"]; I am building a function that acts like Drupal's variable_initialize() function that pulls all key/value pairs into a global variable. I am trying to find the proper parameters I need to put into fetchAll() to remove the row number and get basically what fetch(PDO::FETCH_ASSOC) does but for all returned rows. I basically want fetchAll to return: Code: [Select] Array { [name] = value, [name2] = value2, [name3] = value3, } The variable table is a simple 2 column table (name)|(value) Code: [Select] function variable_init() { global $db, $variable; $query = "SELECT * FROM variable"; $stmt = $db->prepare($query); $stmt->execute(); $result = $stmt->fetchAll(); //need help here foreach($result as $name => $value) { $variable[$name] = $value; } } I have tried PDO_COLUMN/PDO_GROUP/etc... but I can't seem to offset the array to remove the row numbers. Thanks. When I enable error_reporting this notice appear: Notice: Undefined offset: 1 This is code: function get_value_of($name) { $lines = file("../config.php"); $val = array(); foreach (array_values($lines) AS $line) { list($key, $val) = explode('=', trim($line) ); if (trim($key) == $name) { $val = convEnt($val); return $val; } } return false; } Error is in this line: list($key, $val) = explode('=', trim($line) ); How to fix this? I have an array, $old_array, that looks like this (each line is a different index): 1|1|0|20|0|0 1|2|0|20|0|0 1|3|0|20|0|0 1|4|0|20|0|0 1|5|0|20|0|0 1|6|0|20|0|0 1|7|0|20|0|0 33|3|0|15|0|0 33|4|0|15|0|0 33|5|0|15|0|0 34|1|0|15|0|0 34|2|3|15|0|0 34|3|2|15|0|0 34|4|3|15|0|0 34|5|0|15|0|0 34|6|2|15|0|0 34|7|0|15|0|0 It is an array of strings, which are exploded to create other arrays. Anyways, then I have a foreach loop like this: foreach($old_array as $val) { $check = substr($val, 0, strpos( $val,'|',strpos($val,'|')+1)); $array_temp[ $check ] = TRUE; } I am getting this error (ONLY IN INTERNET EXPLORER!): Warning: strpos() [function.strpos]: Offset not contained in string in /home/pgagnon/public_html/chores_uni.html on line 131 Line 131 is this one: $check = substr($val, 0, strpos( $val,'|',strpos($val,'|')+1)); Why does this work in Firefox, Opera, Safari, Chrome, but not IE?? Microsoft can eat shit until it dies! Could someone here explain me the reason for this error in detail..... FYI - i am just more than a fresher in PHP..... Code: [Select] Fatal error: Cannot use string offset as an array Hi
I am having undefined offset:2 and any body can give me an idea, why i get this error message.
for($i = 0; $i< count($from_branch) || $i< count($to_branch) || $i< count($quantity) || $i< count($prio_color); $i++)
{
$query = mysql_query("INSERT INTO pull_out(`description`,`barcode`,`from`,`to`,quantity,prio_color,date_created,remarks,userid) VALUES('$desc','$barc','$from_branch[$i]','$to_branch[$i]','$quantity[$i]','$prio_color[$i]','$datec','$remar','$userid')");
}
and i use checkbox under prio_color and i think this is the cause,
I have the following code: Code: [Select] <?php $lines = count(file("input.txt")); $file = fopen("input.txt", "r"); for($i=0; $i<=$lines; $i++) { $friend = fgets($file); $friendInfo = explode(" ", $friend); $friendID[$i] = $friendInfo[0]; $friendLAT[$i] = $friendInfo[1]; $friendLONG[$i] = $friendInfo[2]; echo $friendInfo[2]; echo $friendLAT[$i]; } fclose($file); ?> The value of $friendInfo[2]; and $friendLAT[$i]; echo out alright. However I get the following output: Quote 0.0 0.0-10.1 10.112.2 -12.238.3 38.3179.9979.99 Notice: Undefined offset: 1 in C:\inetpub\wwwroot\test.php on line 18 Notice: Undefined offset: 2 in C:\inetpub\wwwroot\test.php on line 19 Notice: Undefined offset: 2 in C:\inetpub\wwwroot\test.php on line 21 It doesn't make any sense to me, I can assign the value of the array to a variable ($friendLAT[$i], but it says the offset is undefined. I am writing a script that downloads stock data and graphs the prices using libchart charting library. After downloading data to array $prices, I use the following line to add a new data point to my chart:
$serie1->addPoint(new Point($prices[$i]['date'], $prices[$i]['price']);
$prices contains both date and price keys. However, this throws off illegal string offset error for both keys. I have checked with isset, both variables contain values. I have also tried typecasting, date with (string) and price with (float), but these threw off new errors.
What could be causing the illegal string offset error? Is there a way to silence it?

I am trying to understand why this occurs in a straight forward (spelled out for the complete dumb ass) kind of way. I made the most simple script I could come up with that would produce the error, but I am still uncertain as to what causes it, or what the fix is. Here is the script. Using all the letters and numbers available I print the total characters in the string, run a for statement to print out each character in order from the string index, and get the error "Undefined String Offset 36". Which is the total number of characters in the string starting at 0. The test script can be accessed at the following url: http://icca.exiled-alliance.com/classtest.php $test = "abcdefghijklmnopqrstuvwxyz1234567890"; $b = "<br />"; echo $test; echo $b; echo "There are " .strlen($test). " characters in the above string"; echo $b; for($x=0;$x<=strlen($test);$x++){ echo $test[$x]. "-->number $x"; echo $b; } Can anyone clear up why that error pops up from the way I have this scripted. Hi, I know the problem that I am having is related to the change in PHP5 about strings and arrays, however I do not understand why my script is affected. It seems like I am not trying to add more variables to an array. I do not success in order solve the problem. Help me please: // Build View Array if ($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"]."

What do you call an array that uses integers for the key? I think when the key is text it is called an associative array? Anyways...
Is there a way to create an array where they keys are integers, but you are defining the first entry? I would like my array to either start with a "1" or maybe "1001". How do I do that?
