替換數組值

新手在這裏。我正在嘗試創建一個WordPress插件，並獲取以下代碼以顯示字體選擇的下拉列表。它的工作原理，但看起來錯了，沒有效率，改變數組的顯示值而不寫這些if語句的方法是什麼？替換數組值

$plugin_options = get_option('plugin_options'); 
$plugin_fonts_array = array('Chunk', 'Crimson', 'Deja Vu Sans', 'Deja Vu Sans Condensed', 'Deja Vu Mono', 'Deja Vu Serif', 'Deja Vu Serif Condensed', 'IM Fell French Canon', 'Junction', 'Lato Light', 'Lato Regular', 'Lato Black', 'League Gothic Condensed', 'League Gothic Regular', 'League Script Number One', 'Linux Libertine', 'Linux Libertine Display', 'Linux Libertine Mono', 'OCRB', 'Open Baskerville', 'Open Sans Light', 'Open Sans', 'Open Sans Semi Bold', 'Open Sans Extra Bold', 'Prociono', 'Raleway Thin', 'Source Sans Pro Extra Light', 'Source Sans Pro Light', 'Source Sans Pro', 'Source Sans Pro Semi Bold', 'Source Sans Pro Black'); 
foreach ($plugin_fonts_array as $font) { 
    if ($font == $plugin_options['dropdown1']) { 
     $plugin_front_font = $plugin_options['dropdown1'];  
    if ($plugin_front_font == 'Chunk') { $plugin_front_font = 'chunk'; } 
    if ($plugin_front_font == 'Crimson') { $plugin_front_font = 'crimson'; } 
    if ($plugin_front_font == 'Deja Vu Sans') { $plugin_front_font = 'DejaVuSans'; } 
    if ($plugin_front_font == 'Deja Vu Sans Condensed') { $plugin_front_font = 'DejaVuSansCondensed'; } 
    if ($plugin_front_font == 'Deja Vu Mono') { $plugin_front_font = 'DejaVuSansMono'; } 
    if ($plugin_front_font == 'Deja Vu Serif') { $plugin_front_font = 'DejaVuSerif'; } 
    if ($plugin_front_font == 'Deja Vu Serif Condensed') { $plugin_front_font = 'DejaVuSerifCondensed'; } 
    if ($plugin_front_font == 'IM Fell French Canon') { $plugin_front_font = 'imfellfrenchcanon'; } 
    if ($plugin_front_font == 'Junction') { $plugin_front_font = 'junction'; } 
    if ($plugin_front_font == 'Lato Light') { $plugin_front_font = 'latolight'; } 
    if ($plugin_front_font == 'Lato Regular') { $plugin_front_font = 'latoregular'; } 
    if ($plugin_front_font == 'Lato Black') { $plugin_front_font = 'latoblack'; } 
    if ($plugin_front_font == 'League Gothic Condensed') { $plugin_front_font = 'leaguegothiccondensedregular'; } 
    if ($plugin_front_font == 'League Gothic Regular') { $plugin_front_font = 'leaguegothicregular'; } 
    if ($plugin_front_font == 'League Script Number One') { $plugin_front_font = 'leaguescriptnumberone'; } 
    if ($plugin_front_font == 'Linux Libertine') { $plugin_front_font = 'linuxlibertine'; } 
    if ($plugin_front_font == 'Linux Libertine Display') { $plugin_front_font = 'linuxlibertinedisplay'; } 
    if ($plugin_front_font == 'Linux Libertine Mono') { $plugin_front_font = 'linuxlibertinemono'; } 
    if ($plugin_front_font == 'OCRB') { $plugin_front_font = 'ocrb10'; } 
    if ($plugin_front_font == 'Open Baskerville') { $plugin_front_font = 'openbaskerville'; } 
    if ($plugin_front_font == 'Open Sans Light') { $plugin_front_font = 'opensanslight'; } 
    if ($plugin_front_font == 'Open Sans') { $plugin_front_font = 'opensans'; } 
    if ($plugin_front_font == 'Open Sans Semi Bold') { $plugin_front_font = 'opensanssemibold'; } 
    if ($plugin_front_font == 'Open Sans Extra Bold') { $plugin_front_font = 'opensansextrabold'; } 
    if ($plugin_front_font == 'Prociono') { $plugin_front_font = 'prociono'; } 
    if ($plugin_front_font == 'Raleway Thin') { $plugin_front_font = 'ralewaythin'; } 
    if ($plugin_front_font == 'Source Sans Pro Extra Light') { $plugin_front_font = 'sourcesansproextralight'; } 
    if ($plugin_front_font == 'Source Sans Pro Light') { $plugin_front_font = 'sourcesansprolight'; } 
    if ($plugin_front_font == 'Source Sans Pro') { $plugin_front_font = 'sourcesanspro'; } 
    if ($plugin_front_font == 'Source Sans Pro Semi Bold') { $plugin_front_font = 'sourcesansprosemibold'; } 
    if ($plugin_front_font == 'Source Sans Pro Black') { $plugin_front_font = 'sourcesansproblack'; } 
} 
}

我只是做而不是關聯數組：

$plugin_options = get_option('plugin_options'); 

$font_map = array(
    'Chunk' => 'chunk', 
    'Crimson' => 'crimson', 
    'Deja Vu Sans' => 'DejaVuSans', 
    'Deja Vu Sans Condensed' => 'DejaVuSansCondensed', 
    'Deja Vu Mono' => 'DejaVuSansMono', 
    'Deja Vu Serif' => 'DejaVuSerif', 
    'Deja Vu Serif Condensed' => 'DejaVuSerifCondensed', 
    'IM Fell French Canon' => 'imfellfrenchcanon', 
    'Junction' => 'junction', 
    'Lato Light' => 'latolight', 
    'Lato Regular' => 'latoregular', 
    'Lato Black' => 'latoblack', 
    'League Gothic Condensed' => 'leaguegothiccondensedregular', 
    'League Gothic Regular' => 'leaguegothicregular', 
    'League Script Number One' => 'leaguescriptnumberone', 
    'Linux Libertine' => 'linuxlibertine', 
    'Linux Libertine Display' => 'linuxlibertinedisplay', 
    'Linux Libertine Mono' => 'linuxlibertinemono', 
    'OCRB' => 'ocrb10', 
    'Open Baskerville' => 'openbaskerville', 
    'Open Sans Light' => 'opensanslight', 
    'Open Sans' => 'opensans', 
    'Open Sans Semi Bold' => 'opensanssemibold', 
    'Open Sans Extra Bold' => 'opensansextrabold', 
    'Prociono' => 'prociono', 
    'Raleway Thin' => 'ralewaythin', 
    'Source Sans Pro Extra Light' => 'sourcesansproextralight', 
    'Source Sans Pro Light' => 'sourcesansprolight', 
    'Source Sans Pro' => 'sourcesanspro', 
    'Source Sans Pro Semi Bold' => 'sourcesansprosemibold', 
    'Source Sans Pro Black' => 'sourcesansproblack' 
); 

$dropdown_font = $plugin_options['dropdown1']; 

if (array_key_exists($dropdown_font, $font_map)) { 
    $plugin_front_font = $font_map[$dropdown_font]; 
} else { 
    echo "Invalid font"; 
}

雖然因爲大多數的字體名都只是小寫和不加標點，你也可以做一個通用的功能，然後就佔特殊情況。

無論哪種方式，這段代碼太複雜了。你爲什麼需要這樣做？

+1使用'array_key_exists（）'，而不是一個循環！ – HamZa 2013-03-25 02:22:19

它已經好多了（和作品），謝謝。將博客導出爲pdf時，將字體設置爲封面，標題和正文文本。 – Swissgeek 2013-03-25 03:33:34

@Swissgeek不要忘記檢查它作爲答案:) – HamZa 2013-03-25 08:56:30

您可以嘗試這樣的事：

$plugin_options = get_option('plugin_options'); 
$plugin_fonts_array = array('Chunk', 'Crimson', 'Deja Vu Sans', 'Deja Vu Sans Condensed', 'Deja Vu Mono', 'Deja Vu Serif', 'Deja Vu Serif Condensed', 'IM Fell French Canon', 'Junction', 'Lato Light', 'Lato Regular', 'Lato Black', 'League Gothic Condensed', 'League Gothic Regular', 'League Script Number One', 'Linux Libertine', 'Linux Libertine Display', 'Linux Libertine Mono', 'OCRB', 'Open Baskerville', 'Open Sans Light', 'Open Sans', 'Open Sans Semi Bold', 'Open Sans Extra Bold', 'Prociono', 'Raleway Thin', 'Source Sans Pro Extra Light', 'Source Sans Pro Light', 'Source Sans Pro', 'Source Sans Pro Semi Bold', 'Source Sans Pro Black'); 
$plugin_fonts_flipped_array = array_flip($plugin_fonts_array); 
foreach ($plugin_fonts_array as $font) { 
    if ($font == $plugin_options['dropdown1']) { 
    $plugin_front_font = $plugin_options['dropdown1']; 
     if(isset($plugin_fonts_flipped_array[$plugin_front_font])){ 
      $plugin_front_font = strtolower(str_replace(' ', '', $plugin_front_font)); // remove the whitespace and convert to lower space 
     } 
    } 
}
