Supporting special characters with str_word_count()

What about just

print_r( str_word_count($_GET['q'],1) ); ?

You can also explode( ' ', $string ) on the string and count( $array );

All possible combinations:

$diacritics = 'aàȁáâǎãāăȃȧäåẚảạḁąᶏậặầằắấǻẫẵǡǟẩẳⱥæǽǣᴂꬱꜳꜵꜷꜹꜻꜽɐɑꭤᶐꬰɒͣᵃªᵄᵆᵅᶛᴬᴭᴀᴁₐbḃƅƀᵬɓƃḅḇᶀꞗȸßẞꞵꞛꞝᵇᵝᴮᴯʙᴃᵦcćĉčċƈçḉɕꞔꞓȼ¢ʗᴐᴒɔꜿᶗꝢꝣ©ͨᶜᶝᵓᴄdďḋᵭðđɗᶑḓḍḏḑᶁɖȡꝱdzʣdžʤʥȸDzDžꝺẟƍƌͩᵈᶞᵟᴰᴅᴆeèȅéēêěȇĕẽėëẻḙḛẹȩęᶒⱸệḝềḕếḗễểɇəǝɘɚᶕꬲꬳꬴᴔꭁꭂ•ꜫɛᶓȝꜣꝫɜᴈᶔɝɞƩͤᵉᵊᵋᵌᶟᴱᴲᴇⱻₑₔfẜẝƒꬵḟẛᶂᵮꞙꝭꝼʩꟻfffiflffifflᶠꜰgǵḡĝǧğġģǥꬶᵷɡᶃɠꞡᵍᶢᴳɢʛhħĥȟḣḧɦɧḫḥẖḩⱨꜧꞕƕɥʮʯͪʰʱꭜᶣᵸꟸᴴʜₕiìȉíīĩîǐȋĭïỉɨḭịįᶖḯıɩɪꭠꭡᴉᵻᵼijỻİꟾꟷͥⁱᶤᶦᵎᶧᶥᴵᵢjȷĵǰɉɟʝijʲᶡᶨᴶᴊⱼkḱǩꝁꝃꝅƙḳḵⱪķᶄꞣʞĸᵏᴷᴋₖlĺľŀłꝉƚⱡɫꬷꬸɬꬹḽḷḻļɭȴᶅꝲḹꞎꝇꞁỻLjljʪʫɮˡᶩᶪꭝꭞᶫᴸʟᴌₗmḿṁᵯṃɱᶆꝳꬺꭑᴟɯɰꟺꟿꟽͫᵐᶬᶭᴹᴍₘnǹńñňʼnṅᵰṇṉṋņŋɳɲƞꬻꬼȵᶇꝴꞃꞑꞥᴝᴞNjnjⁿᵑᶯᶮᶰᴺᴻɴᴎₙoᴏᴑòȍóǿőōõôȏǒŏȯöỏơꝍọǫⱺꝋɵøᴓǭộợồṑờốṍṓớỗỡṏȭȱȫổởœɶƣɸƍꝏʘꬽꬾꬿꭀꭁꭂꭃꭄꭢꭣ∅ͦᵒᶱºꟹᶲᴼᴽₒpṕṗꝕꝓᵽᵱᶈꝑþꝥꝧƥƪƿȹꟼᵖᴾᴘᴩᵨₚqʠɋꝙꝗȹꞯʘθᶿrŕȑřȓṙɍᵲꝵꞧṛŗṟᶉꞅɼɽṝɾᵳᴦɿſⱹɹɺɻ®ꝶꭇꭈꭉꭊꭋꭌͬʳʶʴʵᴿʀʁᴙᴚꭆᵣsśŝšṡᵴꞩṣşșȿʂᶊṩṥṧƨʃʄʆᶋᶘꭍʅƪſtstˢᶳᶴꜱₛtťṫẗƭⱦᵵŧꝷṱṯṭţƫʈțȶʇꞇꜩʦʧʨᵺͭᵗᶵᵀᴛₜuùȕúűūũûǔȗŭüůủưꭒʉꞹṷṵụṳųᶙɥựǜừṹǘứǚữṻǖửʊᵫᵿꭎꭏꭐꭑͧᵘᶶᶷᵙᶸꭟᵁᴜᵾᵤvṽⱱⱴꝟṿᶌʋʌͮᵛⱽᶹᶺᴠᵥwẁẃŵẇẅẘⱳẉꝡɯɰꟽꟿʍʬꞶꞷʷᵚᶭᵂᴡxẋẍᶍ×ꭓꭔꭕꭖꭗꭘꭙˣ˟ᵡₓᵪyỳýȳỹŷẏÿẙỷƴɏꭚỵỿɣɤꝩʎƛ¥ʸˠᵞʏᵧzźẑžżƶᵶẓẕʐᶎʑȥⱬɀʒǯʓƺᶚƹꝣᵹᶻᶼᶽᶾᴢᴣ';
str_word_count($string, 1, $diacritics);

Not sure if that third parameter is sufficient to make str_word_count work for non-ASCII symbols. It probably only works with Latin-1 if anything.

As alternative you could count the words with a regex however:

$count = preg_match_all('/\pL+/u', $_GET['q'], $matches);

This works for UTF-8 at least. To fully replicate str_word_count you might need [\pL']+ eventually.

for German language use this :

str_word_count($file, 1, 'ÄäÖöÜüß');

for all other languages - just to replace the special characters with yours (French, Polish etc...)
