How to iterate over multiline text in a textbox in php?
What I am trying to do is write a little helper application for myself that converts a coordinate list to a coordinate list in bb code, like this:
This is what the user will enter:
123|456
And the output will be:
1. [coord]123|456[/coord]
So basically I need something that will allow me to store multi-line text as a php variable and then iterate over that variable, changing each line like in the example above.
Please, help:)

You can create a simple form:
<form method="post">
<textarea name="multilineData"></textarea>
<input type="submit" value="Submit">
</form>
How you can process the submitted form:
<?php
$output = '';
$num = 1;
foreach (explode(PHP_EOL, $_POST['multilineData']) as $row) {
$output .= "$num. [coord]$row[/coord]<br>";
$num++;
}
echo $output;
