I needed a multiexplode which didn't replace my delimiters for 1 other delimiter. Because I
couldn't find one in the examples I made one.
delimiter array:
array('/RTRN/','/BUSP/','/BENM/','/ORDP/','/CSID/',
'/MARF/','/EREF/',
'/PREF/','/REMI/','/ID/','/PURP/',
'/ULTB/','/ULTD/');
input string: /RTRN/MS03//BENM/NL50INGB00012345/BUSP/Europese Incasso/eenmalig/67/INGBNL2A/ING Bank
N.V. inzake WeB///CSID/NL32ZZZ999999991234//MARF/EV45451//EREF/EV45451
REP170112T1106//REMI///EV45451REP170112T1106/
output:
array(
[/RTRN/] => MS03/
[/BENM/] => NL50INGB00012345
[/BUSP/] => Europese Incasso/eenmalig/67/INGBNL2A/ING Bank N.V. inzake WeB//
[/CSID/] => NL32ZZZ999999991234/
[/MARF/] => EV45451/
[/EREF/] => EV45451REP170112T1106/
[/REMI/] => //EV45451REP170112T1106/
[/ORDP/] =>
[/PREF/] =>
[/ID/] =>
[/PURP/] =>
[/ULTB/] =>
[/ULTD/] =>
)
<?php
function multiexplode($delimiters,$string) {
$arrOccurence = array();
$arrEnd = array();
foreach($delimiters as $key => $value){
$position = strpos($string, $value);
if($position > -1){
$arrOccurence[$value] = $position;
}
}
if(count($arrOccurence) > 0){
asort($arrOccurence);
$arrEnd = array_values($arrOccurence);
array_shift($arrEnd);
$i = 0;
foreach($arrOccurence as $key => $start){
$pointer = $start+strlen($key);
if($i == count($arrEnd)){
$arrOccurence[$key] = substr($string, $pointer);
} else {
$arrOccurence[$key] = substr($string, $pointer, $arrEnd[$i]-$pointer);
}
$i++;
}
}
//next part can be left apart if not necessary. In that case key that don't appear in
the inputstringwill not be returned
foreach($delimiters as $key => $value){
if(!isset($arrOccurence[$value])){
$arrOccurence[$value] = '';
}
}
return $arrOccurence;
}
?>
