Hi,

Can anyone explain why when I run the attached script I am getting a Rec_Num_30  followed by a Pos_Num_1 at the end? This seems to be some type or error but I cannot determine what's causing it.

Your help will be greatly appreciated.

You might want to remove the trailing tilde.
<?php // RAY_temp_honya.php
error_reporting(E_ALL);

$ediinvoice ="ST*810*8001~BIG*980226*INV123456*980131*PONUM-1234567~N1*SF**15*216793X~N1*ST**15*6678157~N1*BT**15*1135309~N1*VN**15*2002450~DTM*011*980226***19~IT1*1*16*UN*29*SR*IB*0835209881~CTP**SLP*29***DIS*.57~SAC*N~LM*BI*ACK~LQ**AC~IT1*2*32*UN*29.5*SR*IB*0835210020~CTP**SLP*29.5***DIS*.57~IT1*3*32*UN*26*SR*IB*0835210456~CTP**SLP*26***DIS*.57~IT1*4*48*UN*24*SR*IB*0835210979~CTP**SLP*24***DIS*.57~IT1*5*20*UN*6.99*SR*IB*0835211614~CTP**SLP*6.99***DIS*.57~IT1*6*40*UN*5.5*SR*IB*0835212653~CTP**SLP*5.5***DIS*.57~IT1*7*40*UN*6.99*SR*IB*0835209784~CTP**SLP*6.99***DIS*.57~IT1*8*20*UN*8.95*SR*IB*0835213153~CTP**SLP*8.95***DIS*.57~TDS*383750*383750*218736~CTT*8~SE*29*8001~";

// REMOVE THE EXTRANEOUS DELIMITER
$ediinvoice = rtrim($ediinvoice, '~');

$lines = explode("~", $ediinvoice);

$n = 0;
foreach ($lines as $edirecords)
{
    $n++;
    $p =0;
    $rec = '<span style="color:red";>Rec_Num_'.$n.':'.'</span>';
    echo $rec . " " . $edirecords . "<br/>";

    $line = explode("*", $edirecords);
    foreach ($line as $edirecord)
    {
        $p++;
        $pos = '<span style="color:green";>Pos_Num_'.$p.':'.'</span>';
        echo $pos . " " . $edirecord . "<br/>";
    }
echo "<hr/>";
}
