PHP: query a PostgreSQL database

Hi
I'm running PHP version 5.3.5 on a standalone (No internet) fedora 12

I need to build a search web page to query a PostgreSQL database I can't use PDO because the driver is missing

pg_connect works so how do I write a select query that can take 1 or more user parameters from a front end form and loop through the results

At this stage I'm just trying to work out how to query the database safely  eg bind the user parameters to prevent SQL Injection  

I get SQL syntax error on the where clause I think the array isn't being passed into $1

syntax error at or near "," line XX:  name like $1 , array("Trevor%")

<?php
error_reporting(E_ALL);

// Connect to a database named "mary"
$dbconn = pg_connect("dbname=mary") or die("Cannot connect ".  pg_last_error()) ;

$name = "Trevor%";  // simulate $_POST 

$SQL = <<<SQL
Select name,age,address from my_table where name like $1" , array("$name"));
SQL;
 // actual query is over multi lines

$results= pg_query($SQL) or die("Cannot connect ".  pg_last_error()) ;

if($results){
// loop through results building HTML
  while($row = pg_fetch_array($result, NULL, PGSQL_ASSOC)){
            echo "<p>Name:" . $row['name'] . "age: " .$row['age'] .  "address:" . $row['address'] . "</p>";
  }
}// end if results
else{
      echo "<p>No Data </p>";
}
