Picking text between two words with regex

Question

I would like a light for my problem. My goal is to pick up the list below by dividing the blocks between the words LOREM and LOREM but I don’t want to pick up the whole text that follows at the end of the list pattern, as follows example:

LOREM : 10505050
IPSUM : 1050051051084
DOLOR : 2620620620652
AMETI : 54084840540540
LOREM : 10505050
IPSUM : 1050051051084
DOLOR : 2620620620652
AMETI : 54084840540540
LOREM : 10505050
IPSUM : 1050051051084
DOLOR : 2620620620652
AMETI : 54084840540540
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,
quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse
cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

I’m using this regex: /(?=LOREM :).+?(?:(?=LOREM :))/s I’m able to select all, but the last block of text I can’t select.

Answer 1

I suggest two approaches:

#1: By steps

I could divide that text into the "interesting part" and throw away the rest using for example ([^\.]+[\d]+).

Then I’d just stick to the pattern chave : valor and could make a simpler match that would give an array with each line. Something like this:

$regex = '(([\w]+) : ([\d]+))';
preg_match_all($regex, $string, $matches);

#2: Regex grouping catch

It could have a regex that directly captures groups, which implies that its group pattern is consistent. A suggestion is to do so:

$regex = '(([\w]+ : [\d]+[\s\n\r]){4})';
preg_match_all($regex, $string, $matches);

Answer 2

1 - Use strlen

It returns the length of a text passed as argument. Example of using the strlen function:

<?php
    /*string strlen (string entrada)*/
    $qtd_char = strlen("Linha");
    echo $qtd_char;
?>

**The value displayed will be "6", because the text "Line of Code" contains six characters.*

2 º With the amount of text purchased use the Replace.

The substr is responsible for returning a piece of the string. For this it uses three parameters: the string itself, the initial index and the number of characters to be returned.

It turns out that we can also use a negative index, so PHP analyzes the string by counting N characters from the end, not from the beginning. Here are some examples:

<?php

$texto = "eu não sou besta pra tirar onda de herói";

echo substr($texto, 0, $qtd_char);  // eu não sou besta

?>

We can also use substr() in combination with strpos(). strpos detects the position a string takes within an expression.
