PHP search $ keyword result equals to another result at the same time

PHP search $ keyword result equals to another result PHP + mysql. for example, if I want to search for a keyword $ keyword with a value of 25*50, the results of 25*50 and 50*25 are displayed at the same time, then, the search result of 25*50*2.5 is displayed, and the result of 50*25*2.5 is displayed. (25*50*1.1 to 25*50*4.75)
How to judge or use PHP.

Please provide test data

Get submit $ keyword data is 25*50
The result obtained by the following method also shows 50*20. However, if you continue searching for 25*50*2.5, only 25*50*2.5 is displayed, but 50*25*2.5 is not displayed.

$ CArr = array ();
If (! Empty ($ keyword )){
$ CArr ['keyword'] = $ keyword;
}
Require_once ('/config. search. php ');
$ Skeys = array_keys ($ s_replaceArr );
If (@ $ s_replaceArr [$ keyword])
{
$ CArr ['keyword'] = $ s_replaceArr [$ keyword] ['single '];
} Else {
$ Eregpatt = implode ('|', $ skeys );
Preg_match_all ("/^ ($ eregpatt)/", $ keyword, $ res );
// Print_r ($ res );
If ($ res [1]) {
$ KeywordArr = array ();
Foreach ($ s_replaceArr [$ res [1] [0] ['mixed'] as $ svalue)
{
$ KeywordArr [] = preg_replace ("/{$ res [1] [0]}/", $ svalue, $ keyword, 1 );
}

$ CArr ['keyword'] = implode ("", $ keywordArr );
}

}
The config. search. php data is
$ S_replaceArr = Array (
'20 * 40' => array (
'Single '=> '20*40 40*20 ',
'Mixed' => array ('20 * 40', '40*20 ')
),
'40 * 20' => array (
'Single '=> '40*20 20*40 ',
'Mixed' => array ('20 * 40', '40*20 ')
),
'25 * 50' => array (
'Single '=> '25*50 50*25 ',
'Mixed' => array ('25 * 50', '50*25 ')
),
'50 * 25' => array (
'Single '=> '50*25 25*50 ',
'Mixed' => array ('25 * 50', '50*25 ')
)
);
?>
I have many combinations after 25*50. I really don't want to write them one by one to config. search. php. Is there any good solution? thanks to the moderator.

What you may want is this

$ Key = '20*50 * 30'; $ arr = explode ('*', $ key); print_r (Arrangement ($ arr )); // arrange Arrangementfunction Arrangement ($ arr = array (), $ res = '') {if (! Is_array ($ arr) $ arr = str_split ($ arr); if (empty ($ arr) $ array [] = $ res; else foreach ($ arr AS $ k => $ v) {unset ($ arr [$ k]); foreach (Arrangement ($ arr, trim ("$ res * $ v", '*') AS $ t) $ array [] = $ t; $ arr [$ k] = $ v ;} return $ array ;}

Array(    [0] => 20*50*30    [1] => 20*30*50    [2] => 50*30*20    [3] => 50*20*30    [4] => 30*20*50    [5] => 30*50*20)

The moderator writes well.
The last question is how can I accept this array?

$ Arr = Array ("[0]" => "20*50*30", "[1]" => "20*30*50 ", "[2]" => "50*30*20", "[3]" => "50*20*30 ", "[4]" => "30*20*50", "[5]" => "30*50*20 ", "[6]" => "25*50*25"); $ key = "25*50*2.5"; $ arr = explode ('*', $ key ); // print_r (Arrangement ($ arr); // arrange Arrangementfunction Arrangement ($ arr = array (), $ res = '') {if (! Is_array ($ arr) $ arr = str_split ($ arr); if (empty ($ arr) $ array [] = $ res; else foreach ($ arr AS $ k => $ v) {unset ($ arr [$ k]); foreach (Arrangement ($ arr, trim ("$ res * $ v", '*') AS $ t) $ array [] = $ t; $ arr [$ k] = $ v ;} return $ array ;}

Array ([0] => 25*50*2.5 [1] => 25*2.5*50 [2] => 50*2.5*25 [3] => 50*25*2.5 [4] => 2.5*25*50 [5] => 2.5*50*25) to: $ cArr ['keyword'] = 25*50*2.5 25*2.5*50 50*2.5*25 50*25*2.5 2.5*25*50 2.5*50*50*25;

Thanks again to the moderator

The moderator is the moderator!

$ Key = $ keyword; $ arr = explode ('*', $ key); // print_r (Arrangement ($ arr )); // arrange Arrangementfunction Arrangement ($ arr = array (), $ res = '') {if (! Is_array ($ arr) $ arr = str_split ($ arr); if (empty ($ arr) $ array [] = $ res; else foreach ($ arr AS $ k => $ v) {unset ($ arr [$ k]); foreach (Arrangement ($ arr, trim ("$ res * $ v", '*') AS $ t) $ array [] = $ t; $ arr [$ k] = $ v ;} return $ array;} $ aarray = Arrangement ($ arr); $ cArr ['keyword'] = implode ("", $ aarray); echo $ cArr ['keyword'];

Finally succeeded. Thanks again to the moderator
