本文实例讲述了php分割合并两个字符串的函数。分享给大家供大家参考。具体实现方法如下：
这里实现把两个字符串进行分割合并，例如str1=aaaa，str2=bbbb，合并后生成abababab

/** * Merges two strings in a way that a pattern like ABABAB will be * the result. * * @param string $str1 String A * @param string $str2 String B * @return string Merged string */function MergeBetween($str1, $str2){ // Split both strings $str1 = str_split($str1, 1); $str2 = str_split($str2, 1); // Swap variables if string 1 is larger than string 2 if (count($str1) >= count($str2)) list($str1, $str2) = array($str2, $str1); // Append the shorter string to the longer string for($x=0; $x < count($str1); $x++) $str2[$x] .= $str1[$x]; return implode('', $str2);}//范例演示：print MergeBetween('abcdef', '__') . "\n";print MergeBetween('__', 'abcdef') . "\n";print MergeBetween('bb', 'aa') . "\n";print MergeBetween('aa', 'bb') . "\n";print MergeBetween('a', 'b') . "\n";/*Output:a_b_cdefa_b_cdefbabaababab*/ |
