<?php<br />
$guanjianci='德国|荷兰|丹麦|葡萄牙';<br />
//或者$guanjianci=("德国"."荷兰"."丹麦"."葡萄牙");<br />
$varchar='德国和丹麦都在第一场比赛1-0获胜,在次轮比赛中,德国2-1击败荷兰,两场小组赛战罢,德国队虽然拿到了6分,但依然未能保证出线,最后一场如果输给丹麦仍然有出局可能。丹麦上一场在0-2落后的情况下连追两球,但最后还是2-3输给葡萄牙,将小组次席拱手让给葡萄牙。<br />
<br />
丹麦想要出线必须力争击败德国,好在他们也不缺乏击败德国的感觉。在两队最近3场交手中,丹麦令人吃惊地2胜1平占据上风,最近一次交手是在2010年8月,丹麦在落后两球情况下扳平比分。两队上一次在欧洲杯交手则是1992年欧洲杯决赛,当时正是丹麦童话的巅峰,北欧人2-0击败德国夺冠。<br />
<br />
在德国队前两场比赛中,戈麦斯成为最大的亮点。超级马里奥连续两场比赛包揽了德国3粒进球,恐怖的是他进3球居然只花了6脚射门。戈麦斯目前以3球排名射手榜首位,自从1976年欧洲杯穆勒单届射进4球以来,德国队此后36年还没有任何球员欧洲杯单届进球超过3个。左边锋波多尔斯基在此前两场小组赛均打满全场,国家队出场次数达到99场,本场有望实现百场。<br />
<br />
双方都没有对首发阵容进行大的调整,德国队只是因为博阿滕停赛而派上了本德,丹麦也只换上鲍尔森,队内元老罗梅达尔因伤缺席。本场德国前锋波多尔斯基迎来国家队第100场比赛,小将本德则是首次在国家队首发。<br />
<br />
第2分钟,赫迪拉禁区前沿左侧传中,中路无人拿到皮球,后点穆勒胸部停球后左脚抽射稍稍高出。第5分钟,丹麦左侧角球,本特纳远点头球攻门被诺伊尔拿到。1分钟后,德国迅速反击,厄齐尔左侧直塞,波多尔斯基传中,克亚尔解围不力,穆勒门前3米处射门被安德森神奇化解。第12分钟,戈麦斯禁区外围左脚远射高出。';<br />
<br />

echo $abb;//德国<br />

文本'$varcha'中匹配查找关键词'$guanjianci',
①输出'echo'重复率最高的匹配关键词,
②如有多个重复率是一样的,则输出'echo'第一个'$abc[0]'关键词,
③如果没有匹配的关键词,则输出'echo'无。
如上面’$guanjianci‘德国重复率最高,则输出echo‘德国’。
