如何在php正则表达式中排除个案

Question

我想捕获冒号存在的特定数据。我曾经尝试这样做：

preg_match_all("/^(.+):(.+)/im", $input_lines, $output_array); 

该输入数据

last_name, first_name 
bjorge philip: hello world  
bjorge:world 
kardashian, kim 
some http://hi.com ok 
jim https://hey.com yes 
same http://www.vim.com:2018 why 
it's about 20/08/2018 1:23 pm 
time is 01:20:24 now 
capture my name : my name is micky mouse 
mercury, freddie 
I need to be: 
captured 
    capture me :  
if you can 
where is : freddie 
freddie is not: 
home 

我需要捕获bjorge philip: hello world，bjorge:world，I need to be: captured，capture me : if you can，where is : freddie，freddie is not: home和capture my name : my name is micky mouse线和排除包含任何时间任何线或URL

<?php 
$input_lines="last_name, first_name 
bjorge philip: hello world  
bjorge:world 
kardashian, kim 
some http://hi.com ok 
jim https://hey.com yes 
same http://www.vim.com:2018 why 
it's about 20/08/2018 1:23 pm 
time is 01:20:24 now 
capture my name : my name is micky mouse 
mercury, freddie 
I need to be: 
captured 
    capture me :  
if you can 
where is : freddie 
freddie is not: 
home "; 

preg_match_all("/^|\n(?![^:]*$|.*?https?:|.*\d:\d+)(.*?:\s*\r?\n.*|.*?:\s?.+)/",$input_lines,$output_array); 
// \r? can be omitted from regex depending on system 

foreach($output_array[0] as $output){ 
    echo $output,"<br>"; 
} 

Regex pattern bre akdown：

^|\n      #start string from beginning of $input_lines or after any newline 
    (?!     #begin negative lookahead group 
     [^:]*$   #ignore lines with no colon 
     |    #OR 
     .*?https?:  #ignore lines with http: or https: 
     |    #OR 
     .*\d:\d   #ignore lines with digit colon digit 
    )     #end negative lookahead group 
    (     #begin capture group 
     .*?:\s*\r?\n.* #capture 2 lines if 1st line has a colon then 0 or more 
         # spaces with no non-white characters before the newline 
     |    #OR 
     .*?:\s?.+  #capture 1 line when it contains a colon followed by 
         # 0 or 1 space then 1 or more non-white characters 
    )     #end capture group 

这将返回：

bjorge philip: hello world 
bjorge:world 
capture my name : my name is micky mouse 
I need to be: captured 
capture me : if you can 
where is : freddie 
freddie is not: home 

我已经花了大量的时间写这为您解决。如果没有进一步扩展样本集，我希望它获得您的批准。
