how to get rid of a comma inserted by imploding

An extra comma is inserted in the beginning. Since I put for ($getTds = 1 instead of for ($getTds = 0. Here:

$tdarr[$getTds]= implode(", ", $tds);

PHP:

in

$tds = array(); //to put each record together to pass it on to the $sql
$tds[]="";
if($_GET["no"]==NULL){
	for ($getTds = 1; $getTds < 1000; $getTds++) {// this divides the tds into 1000 to make it easier to insert in the db table
		if ($getTds % 10 !== 0) {//if not a multiple of 10
				$tds[].= "'".$tdInnerHTML[1][$getTds]."'";
				//echo "<span style=\"font-weight: bold;\">" . $getTds . ")</span>" .$tdInnerHTML[1][$getTds]. " ";//lays out the data
		}else{//if a multiple of 10
				$tdarr[$getTds]= implode(", ", $tds);

			echo $tdarr[$getTds]."<br />\n";
			//$sql = "INSERT INTO ".$acronym." (".$fieldarr.") VALUES (".$tdarr[$getTds].")";
			//echo $sql."\n";
			//mysql_query($sql) or die(mysql_error());
			$tds=array(); //empties the previous array content
		}
	}
}

PHP:

 

I think the second line

$tds[]="";

PHP:

is causing the problem. Try removing it.

 

But then the next occurrence of $tds[] is $tds[].= "'".$tdInnerHTML[1][$getTds]."'";

Won't there be an error?

 

use substr to remove first character(comma)?

$tdarr[$getTds]=substr(implode(", ", $tds),1);

 

califmerchant option is a good option, by I think you have done this wrong.
What you have just done is the following things, lets create an array named tds, than create a cell and sets its value to a null string. Now some stuff loop: if .. set a new cell .. else get the array into and remove everything.
You should remove the $tds[]=""; and change the $tds[].= to $tds[]=.
