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：
代码如下:
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; }
