codeigniter regex_match匹配“两个长度值”

Question

I have this regex_match like -

    regex_match[/^[0-9]{13}$/ ] 

It validates all 13-digit integers. But I can't seem to find a way for allowing only 10-digit and 13-digit integers to pass as input. I tried all kinds of code like

    regex_match[/^[0-9]{13|10}$/ ] ,

    regex_match[/^[0-9]{13}{10}$/ ] 

and even

    regex_match[/^[0-9]{13}$/ ] | regex_match[/^[0-9]{10}$/ ]

but none of them is working. How can I achieve this ?

Answer 1

Try

regex_match[/^([0-9]{13}|[0-9]{10})$/]

You might need to escape the brackets.

Answer 2

Check this..This is tested..

$number="12541254192";
    if( preg_match('/^([0-9]{13}|[0-9]{10})$/', number)==1){
        echo "Matching";
    }else{
        echo "Not Matching";
    }
