從數(shù)據(jù)庫(kù)中提取信息或在頁(yè)面上顯示字符串時(shí)，如何用拉丁字母（如“ e”）替換諸如“é”等法語(yǔ)的重音符號(hào)？更新：鏈接到“ UTF-8貫穿所有”問(wèn)題的主持人能否將此問(wèn)題標(biāo)記為重復(fù)，請(qǐng)解釋一下該主題如何回答“如何將法語(yǔ)重音字符轉(zhuǎn)換為英語(yǔ)等效字符”的問(wèn)題？該問(wèn)題說(shuō)明了如何在數(shù)據(jù)庫(kù)中正確存儲(chǔ)法語(yǔ)字符，然后顯示它們，這很好，但沒(méi)有說(shuō)明如何使用法語(yǔ)重音符號(hào)（如“é”或“à”）轉(zhuǎn)換為“ e”和“ a” 。您可能希望例如轉(zhuǎn)換圖像文件名，因?yàn)镾afari無(wú)法顯示帶有法語(yǔ)字符的圖像，將其從用戶名中刪除或出于其他多種原因。

這將適用于從5.2及更高版本開(kāi)始的PHP版本。使用Wordpress內(nèi)置函數(shù)刪除重音（轉(zhuǎn)換為英語(yǔ)等效項(xiàng)，例如從“é”到“ e”），并且不需要特殊的庫(kù)或擴(kuò)展名。

經(jīng)過(guò)數(shù)小時(shí)的法語(yǔ)口音故障排除，這是唯一在所有經(jīng)過(guò)測(cè)試的情況下都有效的方法

由以下3個(gè)功能組成，基本用法是：

$ str = detect_remove_french（$ str）;

# if the word has a french character return the non french one

function detect_remove_french($str) {

# Tentative no french character version

$no_french_char = remove_accents($str);

# Compare the above to the original str, if they're different it means that indeed the above contained a french

# character

if(strcmp($no_french_char,$str) != 0) {

return $no_french_char; # <- means there WAS a french character detected, so lets return this french char free version

}

# means the french and tentative no-french are exactly the same, so there was no french characters to begin with

# return FALSE

else {

return false;

}

function remove_accents($string) {

if ( !preg_match('/[\x80-\xff]/', $string) )

return $string;

if (seems_utf8($string)) {

$chars = array(
