如何使用strpos查找完全匹配？

Question

如果我寻找war ，如果我查看Award也可以找到：

 $title = "Music award";
 if (strpos($title, 'war') !== false) {
    echo "found";
  }

如果我寻求war我不想获得award

Answer 1

使用正则表达式匹配

$title = "Music award";
if (preg_match('/\bwar\b/', $title) !== false) {
    echo "found";
}

Answer 2

<?php
$string = "We are the music makers and we are the dreamers of dreams.";
$words  = str_word_count($string, 1);
var_dump(in_array('music', $words));
var_dump(in_array('dream', $words));

输出：

bool(true)
bool(false)
