[SOLVED] getting a paragraph to not display first 4 lines

[scarhand]

lets say i have a paragraph like this:

 

hello there

how are

you

today

i am doing fine

i really am

 

what is the simplest way i can have php only echo this:

 

i am doing fine

i really am

[n3ightjay]

wheres the text / paragraph coming from ? database ?

[rhodesa]

<?php
$text = 'hello there
how are
you
today
i am doing fine
i really am';
list(,,,,$trimmed) = explode("\n",$text,5);
print $trimmed;
?>

[rhodesa]

or...with a variable to adjust the number of lines skipped:

<?php
$text = 'hello there
how are
you
today
i am doing fine
i really am';

$skip = 4;
$parts = explode("\n",$text,$skip+1);
print $parts[$skip];
?>

its coming from a database, wrapped with the nl2br function

 

also, how would i remove ONLY the 3rd line?

 

thanks so far rhodesa!

that would depend, are they all going to be split into new lines or would word wrap effect the lines to remove?

 

It they are proper new lines, then you could use:

 

$lines = explode("\n", $text);

for ($i = 4; $i <= count($lines); $i++) {
    print $line . "\n";
}

 

One of many ways I imagine..

to not show line 3..

 

$lines = explode("\n", $text);

for ($i = 0; $i <= count($lines); $i++) {
    if ($i != 2) print $line . "\n";
}

 

Remember array's start at 0 .. so it's index 2 in the array not 3..

...using my imagination:

 

<?php
$text = 'hello there
how are
you
today
i am doing fine
i really am';

$lines = explode("\n",$text);
unset($lines[2]); //Line 3 has an index of 2
$new_text = implode("\n",$lines);
print $new_text;
?>

Oops, on both my examples should be:

 

print $lines[$i] . "\n";
