preg-match-all

问题 I'm using the following function to search for words in a text file. The problem is that this function is case-sensitive. I don't want it to be case-sensitive! How can I make the function case-insensitive? $url = 'files/file.txt'; $thedata = file_get_contents($url); $lines = explode(PHP_EOL, $thedata); $search = 'some search words'; $pattern = preg_quote($search, '/'); $pattern = "/^.*$pattern.*\$/m"; if(preg_match_all($pattern, $thedata, $matches)) { echo implode('<br>', $matches[0]); } else

When I copy PHP code, things look different... array (size=5) 0 => string 'xddss='asdasda'' (length=15) 1 => string 'xddss' (length=5) 2 => string '' (length=0) 3 =>

问题 I have a string that looks like this: aaaaa: lorem ipsum bb: dolor sit amet ccc: no pro movet What would be the best way to split the string into an array and get the following result in PHP? array[0]='aaaaa: lorem ipsum'; array[1]='bb: dolor sit amet'; array[2]='ccc: no pro movet'; I can write a function that finds the position of each ":", finds the length of the word before it, and splits the string.
