[Solved] How to check string contain A-Z or a-z or 0-9 in a string?(php) [closed]

You can make use of the ctype functions on PHP

ctype_alpha and ctype_digit is probably what you are looking for.

Usage:

//For alphabets
if(ctype_alpha('helloworld'))
{
echo "Yeah this is text";
}
//For digits...
if(ctype_digit('45'))
{
echo "Yeah this is a number";
}
