我想将这样的字符串拆分成另一个用逗号分隔的字符串,就像这样的“红色,蓝色,绿色,深蓝色”。
我已经尝试了一个正常的功能,但这会输出“红、蓝、绿、暗、蓝”。我想在同一个标签中加入“Dark”和“Blue”以及任何其他首字母大写的单词,即使只有两个以上的单词。那可能吗?
我的建议是有一本颜色字典,比如小写。然后在字典中的单词之后搜索传入的字符串。如果命中将该颜色添加到输出字符串并添加逗号字符。您需要从输入字符串中删除找到的颜色。
$words = explode(' ',$string);
$tags = '';
$tag = '';
foreach($words as $word)
{
if(ord($word >=65 and ord($word <=65))
{
$tag .= $word.' ';
}
else
$tags .= $word.',';
}
$tags = trim($tags,',').trim($tag);
print_r($tags);
这是我的建议.. 仅在需要时才使用逗号
$var = "roto One Two Three Four koko poko Toeo Towe ";
$var = explode(' ', $var);
$count = count($var);
for($i=0; $i<$count; $i++)
if( (ord($var[$i][0]) > 64 and ord($var[$i+1][0]) > 96) or ord($var[$i][0]) > 96)
$var[$i] .=',';
echo $var = implode(' ',$var);
你可以试试
$colors = "red blue green Dark Blue Light green Dark red";
$descriptors = array("dark","light");
$colors = explode(" ", strtolower($colors));
$newColors = array();
$name = "";
foreach ( $colors as $color ) {
if (in_array(strtolower($color), $descriptors)) {
$name = ucfirst($color) . " ";
continue;
} else {
$name .= ucfirst($color);
$newColors[] = $name;
$name = "";
}
}
var_dump($newColors);
var_dump(implode(",", $newColors));
输出
array
0 => string 'Red' (length=3)
1 => string 'Blue' (length=4)
2 => string 'Green' (length=5)
3 => string 'Dark Blue' (length=9)
4 => string 'Light Green' (length=11)
5 => string 'Dark Red' (length=8)
string 'Red,Blue,Green,Dark Blue,Light Green,Dark Red' (length=45)
在空间上寻找第一个大写字母的循环explode()
应该这样做:
$string = "red blue Dark Green green Dark Blue";
// preg_split() on one or more whitespace chars
$words = preg_split('/\s+/', $string);
$upwords = "";
// Temporary array to hold output...
$words_out = array();
foreach ($words as $word) {
// preg_match() ins't the only way to check the first character
if (!preg_match('/^[A-Z]/', $word)) {
// If you already have a string built up, add it to the output array
if (!empty($upwords)) {
// Trim off trailing whitespace...
$words_out[] = trim($upwords);
// Reset the string for later use
$upwords = "";
}
// Add lowercase words to the output array
$words_out[] = $word;
}
else {
// Build a string of upper-cased words
// this continues until a lower cased word is found.
$upwords .= $word . " ";
}
}
// At the end of the loop, append $upwords if nonempty, since our loop logic doesn't
// really account for this.
if (!empty($upwords)) {
$words_out[] = trim($upwords);
}
// And make the whole thing a string again
$output = implode(", ", $words_out);
echo $output;
// red, blue, Dark Green, green, Dark Blue
