Question

Really quick noob question with php:

I’m trying to create a conditional statement where I can check if a variable partially matches a substring.

More specific in my case:

$cal is the name of a file, I want it so if $cal contains “.cfg” it echos some text.

pseudocode:

<?php if ($cal == "*.cfg")
 {
    echo "Hello ";
 }
?>

In this case, you can simply look at the last four characters of $cal using substr:

if (substr($cal, -4) === '.cfg') {
    echo "Hello ";
}

You should look into regular expressions for more complex problems.
