Hello allam creating a table that is called throughout a function in php, and this will generate a table: that table wil have a lot of rows,my question is that: I need to have 2 colors, and for example: row 1 has color 1, row 2 has color 2, row 3 has color 1, row 4 has color 2, ......just to differentiate themThanks

create a variable for your class name and set it in each row. Then with php change the variable value depending on the row.

If you are generating the table rows from within a for loop, you can use the index of the loop and the modulus operator to determine which css class to use for your row:

for(i = 0; i < length; i++){	if(i % 2 == 1)	{		$cssclass = "AltRow";	}	// do your table row building...}

Here is a piece of code which reads information from a text data file and then echos it back out using the modulus (%) function to determine if the class = hi-lite is needed to change the background colour of the table row.

<table>	 <tr class="hi_lite">		 <th>Date and Time</th>		 <th>Sender</th>		 <th>Email</th>		 <th>Message</th><?phpif ($show_IP){echo '<th>IP Address</th>';   };echo '</tr>';$row=0;while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {	if ($row % 2) { $data_string .= '<tr class="hi_lite"> ';	}	else  { $data_string .= '<tr> ';	}	 	if ($show_IP){$num = count($data);		   }				else {$num = (count($data) - 1 );					   };		   		 for ($c=0; $c < $num; $c++) {			 $data_string .= '<td> ' . $data[$c] . " </td>";			   };		$data_string .= '<tr> ' . "\r\n\t";		$row++;			 };		print $data_string;		$data_string = "";fclose($handle);?></table>
