ltrim and array

[viviosoft]

Hello all,

 

I want to be able to trim data using an array.  For example:

 

I have:

 

REF*19**PHILADELPHIA 02

REF*GG*CUT PILE

 

Which both are separate lines in an array.  I want to remove  REF*19** and REF*GG* from each and be left with PHILADELPHIA 02 and CUT PILE.

 

I was hoping I could use an array to remove the unwanted data from each line and rebuild the array?  Here's what I have currently.  Which of course, throws an error.  I tried in_array() but maybe I just didn't use it correctly?  Thanks for any help you can provide me.

 

<?php

$unwantedData = array ('REF*19**', 'REF*GG*' );
$lineArray = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE');

$newEdiArray = "";

for ($i=0; $i<count($lineArray); $i++) {

            $line    = $lineArray[$i];
            $newLine    = ltrim( $line, $unwantedData );
            $newEdiArray[] = $newLine;
}

?>

Give this a try

function removeRef(&$value)
{
    $value = preg_replace("#^REF\*+[^\*]+\*+#", "", $value);
}

$lineArray = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE');

array_walk($lineArray, 'removeRef');

print_r($lineArray);

 

Output:

Array
(
    [0] => PHILADELPHIA 02
    [1] => CUT PILE
)

 

NOTE: This will remove the text at the beginning of the value if it matches the following criteria:

 

1. Begins with "REF"

2. followed by one or more asterisks

3. followed by one or more non asterisks

4. followed by one or more asterisks

Thanks for the quick reply.  I should have been a bit more clear.  The values that get removed will have different $values.  For example:  they might not all have "REF" in them so I'm not sure that the solution provided will work.  They could be PID*F*MAC*** or MEA**LN* or PID*F*73***, etc.

I ended up using str_replace();  thanks for the help mjdamato!  You actually helped get me on the right track.

 

<?php

  $searchFor = array('REF*19**', 'REF*GG*');
  $lineArray = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE');

  $newEdiArray = "";

for ($i=0; $i<count($lineArray); $i++) {

            $line    = $lineArray[$i];
            $newLine = str_replace( $searchFor, "", $line );
            $newEdiArray[] = $newLine;
}

?>

This is more efficient.

 

function removeRef(&$value, $key, $searchAry)
{
    $value = str_replace($searchAry, "", $value);
}

$searchFor = array('REF*19**', 'REF*GG*', 'PID*F*MAC***');
$lineArray = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE', 'PID*F*MAC***Another name');

array_walk($lineArray, 'removeRef', $searchFor);

<?php

  $searchFor = array('REF*19**', 'REF*GG*');
  $lineArray = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE');

  $newEdiArray = "";

for ($i=0; $i<count($lineArray); $i++) {

            $line    = $lineArray[$i];
            $newLine = str_replace( $searchFor, "", $line );
            $newEdiArray[] = $newLine;
}

?>

 

That could be rewritten simply as

 

$searchFor   = array('REF*19**', 'REF*GG*');
$lineArray   = array('REF*19**PHILADELPHIA 02', 'REF*GG*CUT PILE');
$newEdiArray = str_replace($searchFor, '', $lineArray);
