這篇文章主要介紹了php數(shù)組轉(zhuǎn)成json格式的方法,實(shí)例分析了php操作數(shù)組及json格式數(shù)據(jù)的方法,需要的朋友可以參考下

本文實(shí)例講述了php數(shù)組轉(zhuǎn)成json格式的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：

代碼如下:

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;

}

希望本文所述對(duì)大家的php程序設(shè)計(jì)有所幫助。
