How can a variable be searched for a specific string in PHP?

To search for a specific string within a variable in PHP, you can use the strpos() function. This function searches for the occurrence of a specific substring within a string and returns the position of the first occurrence. You can then use this position to determine if the substring exists within the variable. 

$variable = "This is a sample string";
$searchString = "sample";

if(strpos($variable, $searchString) !== false){
    echo "The string '$searchString' was found in the variable.";
} else {
    echo "The string '$searchString' was not found in the variable.";
}
