[英]How do you detect if a specific word is at the end of a string in php
I have event listings that look like this 我有类似这样的活动清单
PAPA ROACH AT THE PARAMOUNT IN HUNTINGTON ON APR 28, 2015
Im trying to remove everything after the last "ON" 我正在尝试删除最后一个“ ON”之后的所有内容
$s="PAPA ROACH AT THE PARAMOUNT IN HUNTINGTON ON APR 28, 2015";
echo strstr($s, 'ON', true);
I came up with something like this but it removes everything after the first "ON" it detects, is there a way to run this backwards or tell to skip to the last "ON" 我想出了类似的方法,但是它会在检测到第一个“ ON”后删除所有内容,是否有办法向后运行或告诉您跳到最后一个“ ON”
You can use strrpos
function to perform search from the end of the string: 您可以使用
strrpos
函数从字符串末尾执行搜索:
$s="PAPA ROACH ON THE PARAMOUNT IN HUNTINGTON ON APR 28, 2015";
echo substr($s, 0, strrpos($s, ' ON ') + 3); // +3 is to include the word ON
