php检测字符串在数组中存在,php – 检查字符串中是否存在数组元素

假设String是折叠/分隔的值列表

function arrayInString( $inArray , $inString , $inDelim=',' ){

$inStringAsArray = explode( $inDelim , $inString );

return ( count( array_intersect( $inArray , $inStringAsArray ) )>0 );

}

例1：

arrayInString( array( 'red' , 'blue' ) , 'red,white,orange' , ',' );

// Would return true

// When 'red,white,orange' are split by ',',

// the 'red' element matched the array

例2：

arrayInString( array( 'mouse' , 'cat' ) , 'mouse' );

// Would return true

// When 'mouse' is split by ',' (the default deliminator),

// the 'mouse' element matches the array which contains only 'mouse'

假设String是纯文本,并且您只是在其中查找指定单词的实例

function arrayInString( $inArray , $inString ){

if( is_array( $inArray ) ){

foreach( $inArray as $e ){

if( strpos( $inString , $e )!==false )

return true;

}

return false;

}else{

return ( strpos( $inString , $inArray )!==false );

}

}

例1：

arrayInString( array( 'apple' , 'banana' ) , 'I ate an apple' );

// Would return true

// As 'I ate an apple' contains 'apple'

例2：

arrayInString( array( 'car' , 'bus' ) , 'I was busy' );

// Would return true

// As 'bus' is present in the string, even though it is part of 'busy'
