PHP从行中获取第一个单词

Question

我有一个看起来像这样的文件(带有换行符和奇怪的间距):

Player:         Alive: Score: Ping: Member of Team: 
player1         No     16     69    dogs      
bug             Yes    2      63    insects            
name with space No     0      69    cats        
bob             No     0      69    dogs

如何抓住第一列并将其转换为数组？

期望的输出:
$ players [1] ---->"player1"
$ players [2] ---->"bug"
$ players [3] ---->"with space with space"
$ players [4] - --->"鲍勃"

Answer 1

<?php
    $a=file('file.txt');
    $pos=strpos($a[0],'Alive:');
    $res=array_map(function($x) use ($pos){
        return trim(substr($x,0,$pos));
    },$a);
    unset($res[0]);

对于PHP 5.2-

<?php
    $a=file('file.txt');
    $pos=strpos($a[0],'Alive:');
    function funcname($x,$pos){
        return trim(substr($x,0,$pos));
    }
    $res=array_map('funcname',$a,array_fill(0,count($a),$pos));
    unset($res[0]);
