PDO query using dynamic parameter (arrays) - php

Question

I am working out a function that is meant to query to the database using PDO. I am working with arrays to execute. I am getting error HY093. Below is my code
//my function
function test_function($statement,$data,$connect)
{
$gg = implode(',',$data);
$sth = $connect->prepare($statement);
$sth ->execute(array($gg));
$r_result = $sth->fetch();
$show_result = $r_result['0'];
return $show_result;
}
$datas = array("':ids' => 1"," ':stats' => 1");
$showsh = test_function("SELECT COUNT(*) FROM table WHERE col1 > :ids AND col2 =
:stats",$datas,$con);
echo $showsh;
Any guidance will be helpful.

Answer 1

Your first error is in the creation of the array. You're creating an array with 2 strings, instead of an array with 2 key/value pairs. It should be this:
$datas = array(':ids' => 1,':stats' => 1);
Next up is inside of the function. You're turning the $data variable into a string, then passing that inside of an array into your query. Forget all that, and just pass $data into your execute.
$sth = $connect->prepare($statement);
$sth ->execute($data);

Answer 2

Refactor $datas to [":ids" => 1, ":stats" => 1]
Then edit the function:
function test_function($statement,$data,$connect)
{
$sth = $connect->prepare($statement);
$sth ->execute($data);
$r_result = $sth->fetch();
$show_result = $r_result['0'];
return $show_result;
}
If you must not change the $datas format, you must refactor it within the code. Something like:
$correctData = [];
foreach ($datas as $item) {
$elements = explode("=>", $item);
$key = preg_replace("/\s\'/", "", $elements[0]);
$element = preg_replace("/\s\'/", "", $elements[1]);
$correctData[] = [$key => $element];
}
$showsh = test_function("SELECT COUNT(*) FROM table WHERE col1 > :ids AND col2 =
:stats",$correctData,$con);
Edited: preg_replace("(/\s)(\')/", "",... to preg_replace("/\s\'/", "",...

Answer 3

Thank you Aynber for your answer. I am posting an answer using the ? instead of the :. In this answer I am not using the associative array.
function test_function($statement,$data,$connect)
{
$sth = $connect->prepare($statement);
$sth ->execute($data);
$r_result = $sth->fetch();
$show_result = $r_result['0'];
return $show_result;
}
$datas = array(1,1);
$showsh = test_function("SELECT COUNT(*) FROM table WHERE col1 >? AND col2 = ?",$datas,$con);
echo $showsh;
