搜索阵列一个特定值后，怎么取代掉

搜索阵列一个特定值后，如何取代掉?

<br />$fruit = "banana";   <br />$fruits = array("apple","banana","orange");   <br />if( in_array($fruit,$fruits) ) {<br />       //符合条件<br />       //如何把$fruits的"banana"改成"pear"?<br />}<br />

$fruit = "banana";   <br />$fruits = array("apple","banana","orange");   <br />if( in_array($fruit,$fruits) ) {<br />  $fruits[array_search($fruit, $fruits)] = "pear";<br />}<br />print_r($fruits);<br />

Array<br />(<br />    [0] => apple<br />    [1] => pear<br />    [2] => orange<br />)<br /><br />

对于这种需求，一般就不必先用 in_array 检查了

$fruit = "banana";   <br />$fruits = array("apple","banana","orange");   <br />if(false !== ($t = array_search($fruit, $fruits)) ) {<br />  $fruits[$t] = "pear";<br />}<br />print_r($fruits);<br />
