feha Posted April 25, 2010 Share Posted April 25, 2010 Hi, I'm collecting info of the MySQL table structure, so far im getting nice array as below: What I need help with is a regex to extract values from : [Type] => varchar(250) and get them as : [Type] => array('varchar' => '250') ... Any help appreciated, thank you in advance ... Quote Link to comment https://forums.phpfreaks.com/topic/199691-need-a-bit-help-with-regex/ Share on other sites More sharing options...
feha Posted April 25, 2010 Author Share Posted April 25, 2010 Also: Getting as $value1 = "varchar" and $value2 ="250" is OK ... Quote Link to comment https://forums.phpfreaks.com/topic/199691-need-a-bit-help-with-regex/#findComment-1048105 Share on other sites More sharing options...
feha Posted April 25, 2010 Author Share Posted April 25, 2010 I fixed this way: $s = 'varchar(250)'; $result = preg_split('/([0-9]+)/i', $s, -1, PREG_SPLIT_DELIM_CAPTURE); print_r($result); and getting: Array ( [0] => varchar( [1] => 250 [2] => ) ) That's not right result ... :-( Quote Link to comment https://forums.phpfreaks.com/topic/199691-need-a-bit-help-with-regex/#findComment-1048119 Share on other sites More sharing options...

feha Posted April 25, 2010 Author Share Posted April 25, 2010 Thanks, this is better :-) $s = 'varchar(250)'; $result = preg_split('#([a-z]+)\(([0-9]+)\)#i', $s, 0, PREG_SPLIT_DELIM_CAPTURE); print_r($result); I get: Array ( [0] => [1] => varchar [2] => 250 [3] => ) btw the first 0 and last is empty ... result should be something as : Array ( [0] => varchar [1] => 250 ) or ?

cags Posted April 25, 2010 Share Posted April 25, 2010 Don't use preg_split, use preg_match and use the last parameter. Ignore [0]. preg_match('#([a-z]+)\(([0-9]+)\)#i', $input, $out); print_r($out); Quote Link to comment https://forums.phpfreaks.com/topic/199691-need-a-bit-help-with-regex/#findComment-1048136 Share on other sites More sharing options...

feha Posted April 25, 2010 Author Share Posted April 25, 2010 Hello again ... Have still some problems ... $type = 'int'; if(preg_match('/([a-z]+)\(([0-9]+)\)/i', $type, $out)) { } else { preg_match('/([a-z]+)/i', $type, $out); } print_r($out); Is it possible to make it in one pass, regex ... as some times values are: int(10) unsigned, text date not just varchar(250) etc ... so it should match something like: txt int(10) int(10) unsigned but still to get matches ... is this possible with single regex line ? Thank you f Quote Link to comment https://forums.phpfreaks.com/topic/199691-need-a-bit-help-with-regex/#findComment-1048201 Share on other sites More sharing options...
feha Posted April 26, 2010 Author Share Posted April 26, 2010 Hi, I still have some problems ... my current code is: $pattern = "/([a-z]+)\(([0-9]+)\)([a-z]+)|([a-z]+)\(([0-9]+)\)|([a-z]+)/i"; $type = 'int (20) unsigned'; //$type = 'int(20)'; //$type = 'text'; $type = preg_replace('/\s+/','', $type); if(preg_match($pattern, $type, $out)) { echo 1; } echo "<pre>".print_r($out,true); so far it works ok as OR ... if i try: $type = 'int(20) unsigned'; iget Array ( [0] => int(20)unsigned [1] => int [2] => 20 [3] => unsigned ) if i try $type = 'int(20)'; Array ( [0] => int(20) [1] => [2] => [3] => [4] => int [5] => 20 ) an if i try : $type = 'text'; i get: Array ( [0] => text [1] => [2] => [3] => [4] => [5] => [6] => text ) it works, but the problem is i want to use just [1],[2],[3] without having empty values ... is the possible just with RegEX ...

feha Posted April 26, 2010 Author Share Posted April 26, 2010 I solved this by using : foreach ($out as $key => $value) { if ($out[$key] != '') { $temp[] = $value ; } } $out = $temp; But i wonder if there is other way ...
