简单的正则表达式问题：如何找到第一个括号并获取其中的内容？

Question

I'm new to regex with PHP. How can I find the contents of the first parentheses with a string that is a couple of paragraphs long.

I'm assuming I have to use the preg_match function

Answer 1

no need regex, just your normal PHP string functions

$str = "

yada yada yada
yada
yada yada
yada (bada bada
bada bada

bada) yada yada yada
yada yada
yada yada yada
( yo yo )
";

$s = explode(")",$str,2);
$what_i_want=$s[0];
$m = strpos($what_i_want,"(");  #find where opening brace is
print substr($what_i_want,$m+1); #print from opening brace onwards
