PHP - How to check if a string contains a specific text [duplicate]

Answer 1

Do mean to check if $a is a non-empty string? So that it contains just any text? Then the following will work.

If $a contains a string, you can use the following:

if (!empty($a)) {      // Means: if not empty
    ...
}

If you also need to confirm that $a is actually a string, use:

if (is_string($a) && !empty($a)) {      // Means: if $a is a string and not empty
    ...
}
