PHP字符串处理函数中有一个similar_text用于计算两个字符串的相似程度。今天来看看similar_text如何实现的。...similar_text — 计算两个字符串的相似度，返回两个字符串中匹配字符的数目 两个字符串的相似程度。...源码中similar_text函数在内部调用了php_similar_char进行处理。ac是参数的个数。函数返回的是两个字符串中匹配字符的数目。...在php_similar_char中有调用了php_similar_str，在看php_similar_char前，先看看php_similar_str的功能。 ?...在php_similar_char，通过php_similar_str拿到最大相似数目，以及两个字符串起始位置。
For example, “great acting skills” and “fine drama talent” are similar, if the similar word pairs are...For example, if “great” and “fine” are similar, and “fine” and “good” are similar, “great” and “good”...are not necessarily similar....For example, “great” and “fine” being similar is the same as “fine” and “great” being similar....Also, a word is always similar with itself.
