Obtain first line of a string in PHP

Question

In PHP 5.3 there is a nice function that seems to do what I want:

strstr(input,"\n",true)

Unfortunately, the server runs PHP 5.2.17 and the optional third parameter of strstr is not available. Is there a way to achieve this in previous versions in one line?

Answer 1

It's late but you could use explode.

<?php
$lines=explode("\n", $string);
echo $lines['0'];
?>

Answer 2

Many times string manipulation will face vars that start with a blank line, so don't forget to evaluate if you really want consider white lines at first and end of string, or trim it. Also, to avoid OS mistakes, use PHP_EOL used to find the newline character in a cross-platform-compatible way (When do I use the PHP constant "PHP_EOL"?).

$lines = explode(PHP_EOL, trim($string));
echo $lines[0];

Answer 3

echo str_replace(strstr($input, '\n'),'',$input);

Answer 4

try this:

substr($text, 0, strpos($text, chr(10))

Answer 5

$first_line = substr($fulltext, 0, strpos($fulltext, "\n"));

or something thereabouts would do the trick. Ugly, but workable.

Answer 6

try

substr( input, 0, strpos( input, "\n" ) )
