How to splitting words match by patterns with PHP - php

Question

I have an array of words. e.g.,
$pattern = ['in', 'do', 'mie', 'indo'];
I wanna split a words match by the patterns to some ways.
input =
indomie
to output =
$ in, do, mie
$ indo, mie
any suggests?
*ps sorry for bad english. thank you very much!

Answer 1

it was an very interesting question.
Input:-
$inputSting = "indomie";
$pattern = ['in', 'do', 'mie', 'indo','dom','ie','indomi','e'];
Output:-
in,do,mie
in,dom,ie
indo,mie
indomi,e
Approach to this challenge
Get the pattern string length
Get the all the possible combination of matrix
Check whether the pattern matching.
if i understand your question correctly then above #V. Prince answer will work only for finding max two pattern.
function sampling($chars, $size, $combinations = array()) {
if (empty($combinations)) {
$combinations = $chars;
}
if ($size == 1) {
return $combinations;
}
$new_combinations = array();
foreach ($combinations as $combination) {
foreach ($chars as $char) {
$new_combinations[] = $combination . $char;
}
}
return sampling($chars, $size - 1, $new_combinations);
}
function splitbyPattern($inputSting, $pattern)
{
$patternLength= array();
// Get the each pattern string Length
foreach ($pattern as $length) {
if (!in_array(strlen($length), $patternLength))
{
array_push($patternLength,strlen($length));
}
}
// Get all the matrix combination of pattern string length to check the probablbe match
$combination = sampling($patternLength, count($patternLength));
$MatchOutput=Array();
foreach ($combination as $comp) {
$intlen=0;
$MatchNotfound = true;
$value="";
// Loop Through the each probable combination
foreach (str_split($comp,1) as $length) {
if($intlen<=strlen($inputSting))
{
// Check whether the pattern existing
if(in_array(substr($inputSting,$intlen,$length),$pattern))
{
$value = $value.substr($inputSting,$intlen,$length).',';
}
else
{
$MatchNotfound = false;
break;
}
}
else
{
break;
}
$intlen = $intlen+$length;
}
if($MatchNotfound)
{
array_push($MatchOutput,substr($value,0,strlen($value)-1));
}
}
return array_unique($MatchOutput);
}
$inputSting = "indomie";
$pattern = ['in', 'do', 'mie', 'indo','dom','ie','indomi','e'];
$output = splitbyPattern($inputSting,$pattern);
foreach($output as $out)
{
echo $out."<br>";
}
?>

try this one..
and if this solves your concern. try to understand it.
Goodluck.
<?php
function splitString( $pattern, $string ){
$finalResult = $semiResult = $output = array();
$cnt = 0;
# first loop of patterns
foreach( $pattern as $key => $value ){
$cnt++;
if( strpos( $string, $value ) !== false ){
if( implode("",$output) != $string ){
$output[] = $value;
if( $cnt == count($pattern) ) $semiResult[] = implode( ",", $output );
}else{
$semiResult[] = implode( ",", $output );
$output = array();
$output[] = $value;
if( implode("",$output) != $string ){
$semiResult[] = implode( ",", $output );
}
}
}
}
# second loop of patterns
foreach( $semiResult as $key => $value ){
$stackString = explode(",", $value);
/* if value is not yet equal to given string loop the pattern again */
if( str_replace(",", "", $value) != $string ){
foreach( $pattern as $key => $value ){
if( !strpos(' '.implode("", $stackString), $value) ){
$stackString[] = $value;
}
}
if( implode("", $stackString) == $string ) $finalResult[] = implode(",", $stackString); # if result equal to given string
}else{
$finalResult[] = $value; # if value is already equal to given string
}
}
return $finalResult;
}
$pattern = array('in','do','mie','indo','mi','e', 'i');
$string = 'indomie';
var_dump( '<pre>',splitString( $pattern, $string ) );
?>
