[英]How can I use regex to grab the information on the END of a line?
For example, 例如,
http://api.hostip.info/get_html.php?ip=12.215.42.19
When visiting that URL, it will return: 访问该URL时,它将返回:
Country: UNITED STATES (US)
City: Sugar Grove, IL
IP: 12.215.42.19
I want to set Sugar Grove, IL
to a variable, after visiting that URL. 访问该URL后
Sugar Grove, IL
我想将Sugar Grove, IL
, Sugar Grove, IL
设置为变量。
How would I make it find the City, and then set it to a variable? 我将如何找到城市,然后将其设置为变量?
This will do the trick: 这将达到目的:
<?php
$page = "Country: UNITED STATES (US)
City: Sugar Grove, IL
IP: 12.215.42.19
";
preg_match( '/City:\s*([^\n]+)/', $page, $matches );
echo $matches[1];
?>
$x=<<<CODE
Country: UNITED STATES (US)
City: Sugar Grove, IL
IP: 12.215.42.19
CODE;
preg_replace('`\nCity:\s(.*)\r`Ue','$city="$1";',$code);
Of course, we are using eval() here, so only if you are 100% sure of data integrity 当然,我们在这里使用eval(),因此仅当您100%确定数据完整性时
