Can anyone tell me how to take one line from a variable?

Like for example i store information from a textarea in a variable. Now i want to execute each line one by one how to do that?

Can anyone help me please?

You can use the explode() function on the new line breaks (\n) then loop through each line.

i don;t want to start a new thread thats why asking here 

 

PLease tell also this

$link = "<div style=\"text-align: center;\">

 

Why did we add \ in "<div style=\" I mean what does \ gives output here

[JasonLewis]

That will just create in infinite loop in which you will eventually need to break out of. Or it'll just keep looping.

Please reply to my second part also

The back-slash is escaping the quotes. See how the variable is opened with double-quotes (") then the div tag requires double-quotes also. If you didn't have the back-slash in front of the quote PHP would throw an error at you.

Thank you for all the above

But can u tell me how to use explode function  ???

I am not able to get how to use it to get one line from a variable containing many lines

[JasonLewis]

If the data is coming from a textarea tag then you can use it like so:

 

$text = $_POST['textarea'];

$explode = explode(PHP_EOL, $text); //Using PHP_EOL, which is a predefined constant for the End Of Line in different OS
foreach($explode as $lines){
echo $line . "<br>"; //Echo out each line, you can perform whatever you need on the $line
}
