Hi,
is there a way to get just numerical data from a posted array and put into a format of ('n','n','n') so that I can use in a MySQL query

Examples of posted variable subcat below.

Array ( [0] => select_products [1] => 156 )  
Array ( [0] => select_products [1] => 118 [2] => 133 [3] => 134 )
Array ( [0] => 153 [1] => 151 [2] => 152 [3] => 158 [4] => 137 [5] => 138 [6] => 135 ) --->  
Array ( [0] => 174 ) --->  



I want to create something like this from the above
('156')
('118','133','134')
('153','151','158','137','138','135')
('174')


Thanks in advance for your feedback.

Array ( [0] => select_products [1] => 156 )

if(is_array($array)){
      foreach($array as $key=>$value)
      {
            is_numeric($value)
            {
             $data[] = $value
            }
      }
}

echo '<pre>';print_r($data);

try this:

<?php
$a=array("select_products ","156");
$b=array("select_products ","118", "133", "134");
$c=array("153","151","152", "158", "137","138","135");
$d=array("174");


echo "('$a[1]')<br />";
echo "('$b[1]','$b[2]','$b[3]')<br />";
echo "('$a[1]')<br />";
echo "('$c[0]','$c[1]','$c[2]','$c[3]','$c[4]','$c[5]','$c[6]')<br />";
echo "('$d[0]')<br />";
?>

if you want only integers:

<?php

$a = Array ( 0 => 'select_products', 1 => 118, 2 => 133, 3 => 134 ); 
$b = Array ( 0 => 153, 1 => 151, 2 => 152, 3 => 158, 4 => 137, 5 => 138, 6 => 135 );

$a_str = "(";

foreach($a as $val)
    if(is_int($val)) $a_str .= "'".$val."',";
$a_str = substr($a_str,0,-1);
$a_str .= ")";

echo $a_str;

echo"<br /><br />";

$b_str = "(";

foreach($b as $val)
    if(is_int($val)) $b_str .= "'".$val."',";
$b_str = substr($b_str,0,-1);
$b_str .= ")";

echo $b_str;
?>

You can use array_values() to remove the keys from the array.  You can use implode() to create a string from the array, using a comma as the "glue" string.  Then you can use the concatenation operator to wrap the string of numbers in parentheses.  This is a fairly common construct in PHP programming.  But I am curious... What do you mean by a "posted" array?  Where does this data originate?  Can you please show us the CREATE TABLE statement and show us the relationship between the external data and the columns you want to keep in the data base?  The data samples above do not give us much of a clue about how to create the query string that you might need.  Thanks, ~Ray
