can i display just the first line of a post?

[dbradbury]

so up until a line break?

[salathe]

Yes.

[dbradbury]

how would that be done may i ask?

[mattal999]

Could just do

 

$string = "hihihi\nlolol";
echo explode("\n", $string)[0];

Untested btw, but logic seems sound.

so if this was for a variable it would be..?

echo explode("\n", $row1['post_text'])[0];

 

something like that?

 

[mattal999]

Correct. Just to be on the safe side, I would do:

 

echo explode("<br />", nl2br($row1['post_text']))[0];

Because i'm not sure how well \n goes down with strings grabbed from random places.

[dbradbury]

so by logic, put this in it will only show the first line of the varible?

mattal999, function array dereferencing is not implemented in PHP (there has been talk about it in the past, the RFC is currently "declined") so you can't access the 0th array item in that matter.  Also, there is no need to nl2br+explode the entire post (which may, in theory, be huge) if all that is going to be used is the first line.

 

So, on those notes, another way (of many!) would be something like:

 

echo strtok($row1['post_text'], "\r\n");

thanks that worked great!!

 

now now if i wanted to show everything after the first line, would it consist of something similar to that?
