how to split the variable input by users to an array - php

Question

A variable $irn input by the users, I need to pass the variable $irn one by one to a SQL and display the result in GR textbox after clicking the button
Generate Result, I want to split the $irn to an array so I can pass it one by one to the SQL query.
I tried mb_split and preg_split
<?php
include "big2gb.php";
ini_set('default_charset', 'utf-8');
$result = $_GET["listIRN"];
$irn = $_POST["irn"];
$serverName = "192.168.4.75";
$connectionInfo = array( "Database"=>"SAFHKG", "UID"=>"sa1", "PWD"=>"Azsxdc11", "CharacterSet" => "UTF-8");
$conn = sqlsrv_connect( $serverName, $connectionInfo );
if($conn){
//echo "connect DB success!!!<br />";
}
else
{
//echo "successfully failed!!!<br />";
die(print_r(sqlsrv_errors(),true));
}
//find irn
$sql="Select Top 1
[Expression] = CONCAT(OFFICIALNUMBER, ' for ', TITLE, ' in Class ', LOCALCLASSES)
From CASES
INNER JOIN OFFICIALNUMBERS On CASES.CASEID = OFFICIALNUMBERS.CASEID
Where NUMBERTYPE IN ('R', 'A') and CASES.IRN = ('".$array[$i]."')
Order By
CASE
When NumberType = 'R' then -2
When Numbertype = 'A' then -1
End";
echo"
<table>
<form action='test22.php' method='post'>
<tr>
<td>IRN:</td>
<td>
<input type='text' id='txtIRN' value='' style='text-transform:uppercase' >
<input type='button' value='Add IRN' onClick='addIRN()' name=''/>
<input type='submit' value='Genarate Result' id='GR' name=''/>
</td>
</tr>
<tr><tr><tr>
<td><td>
<textarea id='listIRN' name='irn' rows='40' cols='30' >
</textarea><textarea id='GR' rows='40' cols='80' ></textarea>
</td></td>
</tr></tr></tr>
</form>
</table><br/>";
echo"
<script type='text/javascript'>
function addIRN(irn) {
var IRNText = document.getElementById(\"txtIRN\").value;
var IRNList = document.getElementById(\"listIRN\").value;
var irn = IRNList + '\\n' + IRNText;
document.getElementById(\"listIRN\").value = irn.trim().toUpperCase();
}
</script>";
//////////////////your entered//////////////////*
echo "<p>You entered:<p>";
$array = mb_split('\\n', $irn);
foreach($array as $line)
{
$array = explode('\s', $irn);
echo "$line\n";

print_r ($array);

for ($i = 0; $i <= 20; $i++)
{
$result = sqlsrv_query($conn, $sql );
while( $row = sqlsrv_fetch_array( $result, SQLSRV_FETCH_ASSOc) )
{
echo " ". $row["Expression"] ." <br />";
}
}
$conn->close();

strong text
User input will be like TM1150CN31 TM2846CN35 TM2855CN35 TM2865CN35 TM2874CN43 TM3367CN05

Answer 1

You can use explode function like below
$var = 'TM1150CN31 TM2846CN35 TM2855CN35 TM2865CN35 TM2874CN43 TM3367CN05';
$array = explode(' ', $var);
Out put will be like
Array
(
[0] => TM1150CN31
[1] => TM2846CN35
[2] => TM2855CN35
[3] => TM2865CN35
[4] => TM2874CN43
[5] => TM3367CN05
)
