Patrick, I’m not sure this is the best way to do this, it does what you want but again I’m not really sure<\/strong> if using 3 consecutive loops is good practice. In real world environment, your txts files may contain hundreds or thousands of entries wich will make this painful for your server to process, you can have memory problems.
\nHaving said this there is my approach, note that I’ve tested this with different number of lines in each text content to make sure it works.
\nBased on this perhaps you can start another question, maybe someone with more php skills than me can help you improve this.
\nLast but not least, always remember that when asking you must show us your code, your attempts to reach your goals.<\/p>\n
