Write a simple regular Expression tool class

Follow the video, but also personally knocked out of such a regular expression of the class, feel very good, really warm and know the new, originally wanted to put the note to write the high point of a little, today late a bit tired, the first simple to write, have time to perfect perfect.

<?phpclass regextool{//contains some commonly used regular expressions private  $validate =array (' Require '    =>    '/.+/', ' email '      =>   '/^\w+ ([-+.] \w+) *@\w+ ([-.] \w+) *\.\w+ ([-.] \w+) *$/', ' url '        =>   '/^http (s?): \ /\/(?: [A-za-z0-9-]+\.) +[a-za-z]{2,4} (?: [\/\?#][\/=\?%\ -&~ ' @[\]\ ': +!\.#\w]*)? $/', ' Currency '   =>   '/^\d+ (\.\d+)? $/', ' number '      =>   '/^\d+$/', ' Zip '        =>   '/^\d{6 }$/', ' Integer '    =>   '/^[-\+]?\d+$/', ' Double '     =>    '/^[-\+]?\d+ (\.\d+) $/', ' Chinese '    =>   '/^[a-za-z]+$/', ' qq ' = '/^\d{5,11 ' $/', ' mobile ' = '/^1 (3|4|5|7|8) \d{9}$/',);/******************** definition Returns the result of whether the definition matches or is to get a matching result * when false to verify the result, is true  or false   whether to match to *****************/private  $returnMatchResult =false;//definitionFix mode, default to empty private  $fixMode =null;//match result array//Verify matching result if success is true  otherwise   is falseprivate  $isMatch = false;//Constructors   Two parameters   defines the return result type, and the correction mode public function __construct ($returnMatchResult =false,$ Fixmode=null) {$this->returnmatchresult= $returnMatchResult;//assigns a value to the member property $this->fixmode= $fixMode;} /********************************* core Matching method The first parameter of the regular expression, the second is the target data * $pattern   If in the member property $validate, use the ready-made expression directly, Does not exist as he himself is an expression **************************/private function regex ($pattern, $subject) {if (array_key_exists (Strtolower ($pattern),  $this->validate)) {$pattern = $this->validate[$pattern]. $this->fixmode;} Judging return type $this->returnmatchresult?preg_match_all ($pattern,  $subject,  $this->matches): $this Ismatch=preg_match ($pattern,  $subject) ===1;return  $this->getregexresult ();} Depending on getregexresult, returns different results Private function getregexresult () {if ($this->returnmatchresult) {return   $this->matches;} else{return  $this->ismatch;}} //Toggles the returned type, such as when instantiating a Boolean value, and now suddenly wants to match the array public function togglereturntype ($bool =null) {if (empty ($bool)) {$ this->returnmatchresult=! $this->returnmatchresult;} else{$this->returnmatchresult=is_bool ($bool)? $bool:(bool) $bool;}} Toggle Rest mode for the same reason as Public function setfixmode ($fixMode) {$this->fixmode= $fixMode;} Below you can define some common authentication methods//Non-null authentication method Public function noempty ($STR) {return  $this->regex (' Require ', $STR);} Verify Emailpublic function isemail ($str) {return  $this->regex (' email ', $str);} Verify phone number public function ismobile ($str) {return  $this->regex (' mobile ', $STR);} User-defined regular expression Public function check ($pattern, $subject) {return  $this->regex ($pattern, $subject);}} Practical operation, the effect is still rod ^_^ $regex  = new regextool (); $regex  -> setfixmode (' U '); $isEmail =$ Regex -> isemail (' [email protected] '); $isMobile = $regex  -> ismobile (' 56481513 '); Var_dump ($isEmail);echo  '  
After testing, there should be no problem.
