Cutting strings in parts

[stijnvb]

Hi guys,

 

I have long strings which I want to cut in smaller strings into an array.

As an example, they should all be less than 2000 characters, and cut off to the dot (.) closest to the 2000th character.

This way, a string of 10000 characters will likely be cut into 6 parts, all ending with a .

 

What would be the best way to get this done?

Got home and put myself to it

 

I got exactly what I needed, but I think this could be done so much shorter.

 

Anyway, this might be useful for you:

 

<?php
// Split array into sentences (this removes the . after each sentence
$tot_article_array = explode('. ', $tot_article);

$current_add_period = 0;

// Add the . after each sentence again
while ($current_add_period < count ($tot_article_array)){
    $tot_article_array[$current_add_period] .= ".";
    $current_add_period++;
}

$current_combine_count = 0;
$trunk_array_count = 0;
$trunk_array = array();

// Add sentences together to a string closest to 1000 characters
while ($current_combine_count < count ($tot_article_array)){
    if (strlen($trunk_array[$trunk_array_count]) + strlen($tot_article_array[$current_combine_count]) < "1000") {
        $trunk_array[$trunk_array_count] .= " " . $tot_article_array[$current_combine_count];
    }
    else {
        $trunk_array_count++;
    }
    $current_combine_count++;
}
?>

$sentences = preg_split('~(.{1,998}\. )~s',$content,-1,PREG_SPLIT_DELIM_CAPTURE|PREG_SPLIT_NO_EMPTY);

Hi Crayon,

 

Now that's what I call a solution! :-)

That does exactly what I need!!!

 

Thanks
