php数组转成json格式的方法
这篇文章主要介绍了php数组转成json格式的方法,实例分析了php操作数组及json格式数据的方法,需要的朋友可以参考下
本文实例讲述了php数组转成json格式的方法。分享给大家供大家参考。具体实现方法如下:
- function array_to_json( $array ){
- if( !is_array( $array ) ){
- return false;
- }
- $associative = count( array_diff( array_keys($array), array_keys( array_keys( $array )) ));
- if( $associative ){
- $construct = array();
- foreach( $array as $key => $value ){
- // We first copy each key/value pair into a staging array,
- // formatting each key and value properly as we go.
- // Format the key:
- if( is_numeric($key) ){
- $key = "key_$key";
- }
- $key = "'".addslashes($key)."'";
- // Format the value:
- if( is_array( $value )){
- $value = array_to_json( $value );
- } else if( !is_numeric( $value ) || is_string( $value ) ){
- $value = "'".addslashes($value)."'";
- }
- // Add to staging array:
- $construct[] = "$key: $value";
- }
- // Then we collapse the staging array into the JSON form:
- $result = "{ " . implode( ", ", $construct ) . " }";
- } else { // If the array is a vector (not associative):
- $construct = array();
- foreach( $array as $value ){
- // Format the value:
- if( is_array( $value )){
- $value = array_to_json( $value );
- } else if( !is_numeric( $value ) || is_string( $value ) ){
- $value = "'".addslashes($value)."'";
- }
- // Add to staging array:
- $construct[] = $value;
- }
- // Then we collapse the staging array into the JSON form:
- $result = "[ " . implode( ", ", $construct ) . " ]";
- }
- return $result;
- }
