This article will explain in detail how to judge the ID card number of PHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

ID card number

/ * determine whether the parameter string is the Chinese ID card number * @ param $id string or number to be judged * @ return mixed false or array [content array boolean is true] * / function is_citizen_id ($id) {/ / length validation 18-bit ID card X is uppercase $id = strtoupper ($id) If (! (preg_match ('/ ^\ d {17} (\ d | X) $/', $id) | | preg_match ('/ ^\ d {15} $/', $id) {return false;} / / 15-digit old numbers are converted to 18 digits and converted into strings $Wi = array (7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1) $Ai = array ('1th,' 0th, 'Xray,' 94th, '8th,' 7th, '6th,' 5th, '4th,' 3th,'2'); $cardNoSum = 0; if (strlen ($id) = = 16) {$id = substr (0,6). '19'.substr (6,9); for ($I = 0; $I

< 17; $i++) { $cardNoSum += substr($id,$i,1) * $Wi[$i]; } $seq = $cardNoSum % 11; $id = $id.$Ai[$seq]; } //效验18位身份证最后一位字符的合法性 $cardNoSum = 0; $id17 = substr($id,0,17); $lastString = substr($id,17,1); for($i = 0; $i < 17; $i++) { $cardNoSum += substr($id,$i,1) * $Wi[$i]; } $seq = $cardNoSum % 11; $realString = $Ai[$seq]; if($lastString!=$realString) {return false;} //地域效验 $oCity = array(11=>
