如何找到字符排序模式在PHP字符串？ [英] How to find sequenced pattern of characters in a string with PHP?

问题描述

让我们说我有文字的随机块：

说明：

  patternABC＆GT; = 2个字符= IF groupABC发生groupABC一次以上
groupABC +（groupABC）N =序列，其中N＆GT; = 1和顺序GT; 6个字符
 

** A序列必须> 6个字符，以评估

分析：

我如何发现，发生在序列中的任何重复的模式？

  QEBAQEBAQEBAQEBAQEBAQEBA
 

我也想算每组多少次重复：

  QEBA QEBA QEBA QEBA QEBA QEBA = 6
 

另外，根据序列必须> 6个字符以进行评估：

  NO GOOD：AA AA AA
GOOD：AA AA AA AA
 

这将是理想的，如果输出可以存储在一个关联数组，用重复的条目中删除：

  QEBA =＆GT; 6，AA =＆GT; 4，QEBA =＆GT; 3，AA =＆GT; 8，（QEBA =＆GT; 6）＆LT;  -  REMOVE
 

有没有人有时间和放大器;倾斜度来解决这个问题呢？
如果你这样做，你摇滚！

Let's say I have random block of text:

SPECIFICATIONS:

patternABC >= 2 characters = groupABC IF groupABC occurs more than once
groupABC + (groupABC)n = sequence WHERE n >= 1 AND sequence > 6 characters

** A sequence needs to be > 6 characters in order to be evaluated

BREAKDOWN:

How do I find any repeating patterns that occur in sequence?

QEBAQEBAQEBAQEBAQEBAQEBA

I also want to count how many times each group repeats:

QEBA QEBA QEBA QEBA QEBA QEBA = 6

Also the sequence must be > 6 characters in order to be evaluated:

NO GOOD: AA AA AA
GOOD: AA AA AA AA

It would be ideal if the output could be stored in an associative array, with duplicate entries removed:

QEBA => 6, AA => 4, QEBA => 3, AA => 8, (QEBA => 6)<- REMOVE

Does anyone have the time & the inclination to tackle this problem? You rock if you do!

preg_match_all( '/(\S{2,}?)\1+/', $str, $matches );

// Remove duplicates
$matches[0] = array_unique( $matches[0] ); 

foreach ( $matches[0] as $key => $value ) {
    if ( strlen( $value ) > 6 ) {
        $repeated = $matches[1][$key];
        $results[] = array( $repeated => count( explode( $repeated, $value ) ) - 1 );

print_r($results); 

/*

The above assumes a sequence is composed of non-space characters.
