PHP allows you to share user-defined functions hidden by asterisks (*) with four digits in the middle of a mobile phone number.

PHP allows you to share user-defined functions hidden by asterisks (*) with four digits in the middle of a mobile phone number.

Php shields four phone numbers in the middle:

Copy codeThe Code is as follows:
Method 1:
Function hidtel ($ phone ){
$ IsWhat = preg_match ('/(0 [0-9] {2, 3} [\-]? [2-9] [0-9] {6, 7} [\-]? [0-9]?) /I ', $ phone); // fixed phone number
If ($ IsWhat = 1 ){
Return preg_replace ('/(0 [0-9] {2, 3} [\-]? [2-9]) [0-9] {3, 4} ([0-9] {3} [\-]? [0-9]?) /I ',' $1 ***** $ 2', $ phone );
} Else {
Return preg_replace ('/(1 [358] {1} [0-9]) [0-9] {4} ([0-9] {4 }) /I ',' $1 ***** $ 2', $ phone );
}
}

Method 2:
$ Num = "13966778888"
$ Str = substr_replace ($ num, '*****', 3,4 );

Example:

Copy codeThe Code is as follows:
$ Phonenum = "13966778888 ";
Echo hidtel ($ phonenum );

Final output: 139 **** 8888

The php function outputs five digits in the middle of a mobile phone number and uses asterisks to replace them.

Function suohao ($ phone ){
$ P = substr ($ phone,). "*****". substr ($ phone );
Return $ p;
}

An asterisk generated by four digits in the middle of the mobile phone number

That should be easy. If you are familiar with excel, you can replace the function with a star number here. If you are not familiar with it, you can only customize a small tool. You can contact me for customized software.
