Mobile phone number rules

The Code is as follows:	Copy code
$ Regex = "/13 [0-9] {9} | 15 [0 | 1 | 2 | 3 | 5 | 6 | 7 | 8 | 9] d {8} | 18 [0 | 5 | 6 | 7 | 8 | 9] d {8 }/";

Example 1

Determine the mobile phone number:

The Code is as follows:	Copy code
Function is_mobile ($ str ){ Return preg_match ("/^ (d {3}) | (d {3 }-))? 13d {9 }$/", $ str ); }

Instance

The Code is as follows:	Copy code
<? Php Function checkMobile ($ str) { $ Pattern = "/^ (13 | 15) d {9} $ /"; If (preg_match ($ pattern, $ str )) { Return true; } Else { Return false; } } // Call a function $ Str = checkMobile (15800000001 ″); If ($ str) { Echo ("compliant with mobile phone number standards "); } Else { Echo ("not compliant with mobile phone number Standards "); } ?>

Finally, all mobile phone numbers can be verified.

The Code is as follows:	Copy code
Preg_match_all ($ regex, $ row ['mobile'], $ phones ); If ($ phones ){ Correct }

Friendly reminder: it is really difficult to judge the mobile phone number, because the mobile phone number has changed a lot. maybe you have written a regular expression today, and a new number segment will be generated tomorrow. Make a cell phone number segment array and determine whether the array is in the number segment = array (130,131,132 .....) in_array (substr (number, 0, 3), array)
