如何编写此正则表达式与preg_match一起使用?

I have a series of keywords I want to match against an item name to determine if it is a labor line item or not. How can I write the pattern regex so it matches them all in a more succinct block of code?

if(preg_match('/(LABOR)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(SERVICES)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Pull and Prep)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Supervision)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Coordination)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Disposal)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Handling)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Inspect)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Re-ship)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Storage)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Management)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Show Form)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Receive)/i', $Item[Name])){        
    $subtotal += $mysubtotal;
}elseif(preg_match('/(Paperwork)/i', $Item[Name])){
    $subtotal += $mysubtotal;
}

    The pipe, |, with preg_replace and its fifth parameter should be all you need.

    preg_replace('/LABOR|SERVICES|Pull and Prep|Supervision|Coordination|Disposal|Handling|Inspect|Re-ship|Storage|Management|Show Form|Receive|Paperwork/i', '', $Item['Name'], -1, $subtotal);
    

    You might want to use word boundaries as well so you know that it is an exact match (unless laboring, labors, etc are valid?):

    preg_replace('/\b(?:LABOR|SERVICES|Pull and Prep|Supervision|Coordination|Disposal|Handling|Inspect|Re-ship|Storage|Management|Show Form|Receive|Paperwork)\b/i', '', $Item['Name'], -1, $subtotal);
