How would i go about making each line in a text area (defined by a line break obviously not by the width of textarea) be a separate variable

like $line1, $line2 etc

Take a look at explode().

Example:

Code: Select all

<?php

$text = <<< TEXT
look
im
on
different
lines!
TEXT;

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

echo $lines[0];

?>

ok, thanks :)

but i really want each line in it's own variable, for some reason the code above gives all the lines in $lines[0] not just the first line, whereas on php.net it shows taht you can define each line with the pizza pieces example.

i'm doing it this stupid way because i want to add bits of text at the beginning of each line, like an ASCII design (it's a border on the left).

also, how would i count the total number of lines?

thanks a lot

Try exploding the text using \r\n and not just \n....

Code: Select all

<?php

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

echo "Number of lines/vars = ".count($lines)."<br />";
echo "<hr />";

foreach($lines as $key => $value)
echo $key." - ".$value."<br />";

?>

Just mentioning that [php_man]wordwrap[/php_man]() might be a useful solution also.
