PHP mobile phone number regular expression test program code_PHP tutorial

The code is as follows

Function funcMtel($str)//Mobile phone number regular expression test

　{

Return (preg_match("/(?:13d{1}|15[03689])d{8}$/",$str))?true:false;

　}

Test

　18678785887

Return to

false

Cause analysis, after checking it, I found that the above regular expression can only verify those starting with 13,15, naturally those starting with 18 cannot be used

After modification

The code is as follows

Function funcMtel($str)//Mobile phone number regular expression test

　{

　return (preg_match("/(?:1[3|4|5|8]d{1}|15[03689])d{8}$/",$str))?true:false;

　}

Test

　18678785887

Return to

true

This will be successful,

Summary of experience:

Number segments such as mobile phone numbers will be constantly updated. When we write the function, we write it as a public function, so that we can solve this problem.
