Reading String from Database

[travis77]

Hello,

 

I have a field in a database that can hold either a link to an image e.g. photos/image1.jpg or a number e.g. 555-1212.

 

I need our php script to tell the difference between the two. If it is a link, it needs to display the image. If it is a number, it should display the number.

 

Any ideas on how to do this? Thanks in advance!

Is the format of the number going to be xxx-xxxx, eg three numbers followed by a dash then four numbers

 

If is you could use a bit regex:

$var = '555-1234';

if(preg_match("/^([0-9]+){0,3}\-([0-9]+){0,4}/", $var))
{
    echo 'number';
}
else
{
    echo 'image';
}
