PHP如果在数组中，请使用该值执行某些操作

Question

I am trying to check if a value is in an array. If so, grab that array value and do something with it. How would this be done?

Here's an example of what I'm trying to do:

$the_array = array("buejcxut->10", "jueofi31->20", "nay17dtt->30");

if (in_array('20', $the_array)) {

    // If found, assign this value to a string, like $found = 'jueofi31->20'

    $found_parts = explode('->', $found);

    echo $found_parts['0']; // This would echo "jueofi31"    

}

Answer 1

This should do it:

foreach($the_array as $key => $value) {
    if(preg_match("#20#", $value)) {
        $found_parts = explode('->', $value);
    }
    echo $found_parts[0];
}

And replace "20" by any value you want.
