我有两个字符串

$string1 = 'Amateur developer | Photoshop lover| Alcohol scholar |  Internet practitioner';

和

$string2 = 'Amateur developer | Photoshop lover| Alcohol scholar';

如何将这两个字符串PHP与中间的特殊字符（空格和连字符）进行比较？

试试这个与案例进行比较；

  $result = strcmp($string1, $string2);

试试这个进行比较，而不用考虑比较；

  $result = strcasecmp($string1, $string2);

如果 $result 为 0（零），则字符串相等，否则两种情况都不同。

寻找这种比较？

<?php

$string1 = 'Amateur developer | Photoshop lover| Alcohol scholar |  Internet practitioner';

$string2 = 'Amateur developer | Photoshop lover| Alcohol scholar';

if ($string1 == $string2) {

  echo "Strings are same";
} else {

  $stringArray1 = explode(' | ', $string1);
  $stringArray2 = explode(' | ', $string2);

  $diffAre = array_diff($stringArray1, $stringArray2);
  echo "Difference in strings are " . implode($diffAre, ',');
}
?>

输出

Difference in strings are Internet practitioner

尝试这个

$result = strcmp($string1, $string2);

我建议使用 Jaccard 索引，请参阅：https ://gist.github.com/henriquea/540303

<?php

function getSimilarityCoefficient( $item1, $item2, $separator = "," ) {

    $item1 = explode( $separator, $item1 );
    $item2 = explode( $separator, $item2 );
    $arr_intersection = array_intersect( $item2, $item2 );
    $arr_union = array_merge( $item1, $item2 );
    $coefficient = count( $arr_intersection ) / count( $arr_union );

    return $coefficient;
}

$string2 = 'Amateur developer | Photoshop lover | Alcohol scholar |  Internet practitioner';
$string2 = 'Amateur developer | Photoshop lover | Alcohol scholar';

echo getSimilarityCoefficient($string1,$string2,' | ');

?>

如果它们始终被管道 ( |) 分开，而您只想要一个肮脏的检查：

// original strings
$str1 = 'Amateur developer | Photoshop lover| Alcohol scholar |  Internet practitioner';
$str2 = 'Amateur developer | Photoshop lover| Alcohol scholar';

// split them by the pipe
$exp1 = explode('|', $str1);
$exp2 = explode('|', $str2);

// trim() them to remove excess whitespace
$trim1 = array_map('trim', $exp1);
$trim2 = array_map('trim', $exp2);

// you could also array_map them to strtolower
// to take CaSE out of the equation

然后：

// MATCHING ENTRIES

$same = array_intersect($trim1, $trim2);
var_dump($same);

// DIFFERENT ENTRIES
$diff = array_diff($trim1, $trim2);
var_dump($diff);

使用这个similar_text() - 计算两个字符串之间的相似度
