php - How to split text in 2 halves? -

-

i've done so:

if(strlen($block_text) > 2000) {   $half = strlen($block_text)/2;   $second_half = substr($block_text, $half);   $block_text = substr($block_text, 0, $half); }

but problem here $second_half starts in middle of word , $block_text ends in middle of word. possible tweak somehow first half ends after dot . ?

if(strlen($block_text) > 2000) {   $half = strpos($block_text, ".",  strlen($block_text)/2);   $second_half = substr($block_text, $half);   $block_text = substr($block_text, 0, $half); }

now find first dot after half text.

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
