How to separate string in PHP

Question

I have 20 lines of string seperated with "\n"

I have 2 fields to put this string into

$field1 is limited to 10 lines of string

$field2 can store unlimited lines of string

How do I run a php code to seperate the string into 2 fields.

The 1st-10th line will be stored in $field1.

The 11th-20th line will carry over to $field2.

Answer 1

$array = explode("\n", $text);
$field1 = implode("\n", array_slice($array, 0, 10));
$field2 = implode("\n", array_slice($array, 10));

Answer 2

• do an explode by "\n" ,
• iterate through the resulting array
• put the first 10 results in $field1
• put the rest in $field2

Answer 3

$file_array = file($file_name);

$int = 10;

foreach ($file_array as $line)
{
if($int >=0){
array_push($field1,$line);
$int--;
}else{
array_push($field2,$line);
}


}

You can always trim the lines to get rid of the \n.

Answer 4

<?php

preg_match('/^((?:[^\n]*\n){10})([\w\W]*)$/', $str, $matches);

$field1 = $matches[1];
$field2 = $matches[2];  

?>
