Paste text between two words with regex

I suggest two approaches:

# 1: By steps

You could split this text in the "interesting part" and throw away the rest using for example ([^\.]+[\d]+) .

Then I would just stick with the chave : valor pattern and could do 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 Capture

You could have a regex that directly captures groups, which means that your group pattern is consistent. A suggestion is to do so :

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

1 - Use strlen

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

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

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

2nd With the amount of text purchased use Substr .

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

It turns out that we can also use a negative index, so PHP parses 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 that a string occurs within an expression.
