Split Strings in Half (Word-Aware) with PHP

Question

I\'m trying to split strings in half, and it should not split in the middle of a word.

So far I came up with the following which is 99% working :

$te         


        

Answer 1

I tried using a couple of these answers but didn't get the best results so I thought I would share the solution. I wanted to split my titles in half and display one half white and one half green.

I ended up combining word count, the length of the text, the half way point and a third of the string. This allowed me to make sure the white section is going to be somewhere between the third way/half way mark.

I hope it helps someone. Be aware in my code -,& etc would be considered a word - it didn't cause me issues in my testing but I will update this if I find its not working as I hope.

public function splitTitle($text){

    $words = explode(" ",$text);
    $strlen = strlen($text);
    $halfwaymark = ceil($strlen/2);
    $thirdwaymark = ceil($strlen/3);

    $wordcount = sizeof($words);
    $halfwords = ceil($wordcount/2);
    $thirdwords = ceil($wordcount/3);

    $string1 ='';
    $wordstep = 0;
    $wordlength = 0;


    while(($wordlength < $wordcount && $wordstep < $halfwords) || $wordlength < $thirdwaymark){
        $string1 .= $words[$wordstep].' ';
        $wordlength = strlen($string1);
        $wordstep++;
    }

    $string2 ='';
    $skipspace = 0;
    while(($wordstep < $wordcount)){
        if($skipspace==0) {
            $string2 .= $words[$wordstep];
        } else {
            $string2 .= ' '.$words[$wordstep];
        }
        $skipspace=1;
        $wordstep++;
    }

    echo $string1.' '.$string2.'';

}
