html - how can i stop some words/letters from being swapped in php? -


i using php swap text 1 textarea , display in another, , of works, sadly parts dont.

i using str_ireplace , far, 60 different words, many more come. couple of examples of problem are:

old - auld old man - gadgie

if above, first word unswapped , second new word. however, if put old man in text, come "auld man" instead of "gadgie".

i know may because have declared "old-auld" before "old man - gadgie"

but problem that:

yes - aye no - nar

again, first word original, second after swap. if write "yesterday" displayed "ayeterday" or if had "nose" "narse"

is there anyway change "yes" on own , not if part of word?

and there way have "old man" , "old" separate replacements?

hope makes sense

my code str_ireplace:

<form method="post" action="post.php" > <textarea name="status2" cols="50" rows="5"/> <?php echo str_ireplace(array  ('old','awkward','all','again','behind','along','alright','hello','among','children','yes','child','kids','food','barnard castle','beer','book','blow','beautiful','bird','burst','brown','burn','boots','came','nice','cold','church','clothes','stick','dirty','clever','cloth','cow','crow','stool','crown','pigeon','dad','darlington','dead','do','devil','dont','do not','durham','down','drown','punch','ditch','eye','fall','trouble','condition','four','stupid','old man','go','going','jumper','give over','grandad','hold','get away','home'),  array ('auld', 'aakwad', 'aall','agyen','ahint','alang','alreet','alreet','amang','bairns','aye','bairn','bairns','bait','barney','beor','beuk','blaa','bonny','bord','borst','broon','bourn','byeuts','cam','canny','card','chorch','claes','clag','clarty','clivvor','cloot','coo','craa','cracket','croon','cushat','da','darlo','deed','dee','deil','divvent','divvent','dorham','doon','droon','dunsh','dyke','eee','faa','fash','fettle','fower','gaumless','gadgie','gan','gannin','ganzie','giveower','granda','haad','hadaway','hyem'),$status); ?>   </textarea><br>

as said, there 60+ words.

i didn't add code thought may not have been relevant.

about first part. should replace more specific word first. i.e "old man", , "man" or use strtr

<?php $trans = array("h" => "-", "hello" => "hi", "hi" => "hello"); echo strtr("hi all, said hello", $trans); ?> above example output: hello all, said hi

about whole words. may regexps (and \b in particularly)

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
