How to search the key values in the array – array_search

By Raja sekar May 13, 2015

If we have a very large array values in Indexed or Associative array, we have to search or filter the particular array value or key.

Array_Search function is used to find the value.

This function used to search an array for a value and returns the key.

<?php
$search =array('a'=>'php','b'=>'css','c'=>'html,'d'=>'dssd','e'=>'eeee',f=>'fdfd','g'=>'dsfsd',....);
echo array_search('css',$search);
?>

<?php

$search =array('a'=>'php','b'=>'css','c'=>'html,'d'=>'dssd','e'=>'eeee',f=>'fdfd','g'=>'dsfsd',....);

echo array_search('css',$search);

?>

In the Given example, we have to find whether “CSS” Find or not in the array. It prints the key of the value.

Output

b // output

Explaination

array_search is used to search the array value(‘css’) and returns the value’s key(‘b’);

2. In_array()

In_array is simillar to the array_search

In_array Functions is used to find the value in the array list

using this function you can find the value is present or not in array queue.

syntax: In_array();

you can search anything value or key using IN_ARRAY();

for example

have to find “Developerdesks” in the given array

<?php

$var = array(‘raj’,’sekar’,’developer’,’desks’,'php','html','css','developerdesks','designer');

if(in_array('developerdesks', $var, ))
{
echo "found Developerdesks";
}
else
{
echo "not found";

}

A multidimensional array is an array containing one or more arrays.

Three-Dimensional array

For three dimensional array u have to use two for loop condition
find 0 indexed array value and then 0 indexed array value

<?php

$developedesks = array(
"Skills" => array
(
"php" => 80,
"css" => 85,
"html" => 80
),
"design" => array
(
"photoshop" => 70,
"flash" => 75,
"indesign" => 72
),
"framework" => array
(
"wordpress" => 85,
"drupal" => 75,
"joomla" => 70
)
);

$count = count($developedesks);
echo "$count<br/>";
foreach($developedesks  as $develop => $desks)
{

foreach($desks as $key =>$value)
{
echo "$develop &nbsp; $key &nbsp; $value<br/>";

),

"design" => array

(

"photoshop" => 70,

"indesign" => 72

),

"framework" => array

(

"wordpress" => 85,

"drupal" => 75,

"joomla" => 70

)

);

$count = count($developedesks);

echo "$count<br/>";

foreach($developedesks as $develop => $desks)

{

foreach($desks as $key =>$value)

{

echo "$develop   $key   $value<br/>";

}

?>

Explain

First foreach consider skill as $develop and php =>80 as $desks

Second For each consider $key as php and $ value as 80

so the $develop –> indexed as skill, $key–> indexed as php and $value indexed as 80

simple foreach concept worked

Output

Skills  php  80
Skills  css    85
Skills  html   80
design  photoshop 70
design  flash    75
design  indesign   72
framework wordpress 85
framework drupal   75

How to print array values in php using find i value – Indexed array

By Raja sekar May 13, 2015

How to print array values indexing in php using Indexed array

< ?php

$design = array(‘photoshop’,’flash’,’dreamviewer’,’html5′);

echo $design[0]; //output is photoshop

echo $design[1]; //output is flash

?>

If you know the total number of array values means you can do like this,

For unknown and unlimited array values are present then go to Forloop

Example

< ?php
$var1 = array('one','122','122','122','dfd','dfgdf','dfgdfg','dfgdfg','dfgdfgf','dfgdfg','dfgdfgdf','gfdgdfg','dfgdfgdf','fdg','dfgdf','last');

$total = count($var1); // Use Count(); functions

for($i=0; $i< $total; $i++)
{
echo "$var1[$i]
";
}
?>

$total = count($var1); // Use Count(); functions

for($i=0; $i< $total; $i++)

{

echo "$var1[$i]

";

}

?>

To know the array total values use count(); Functions

2. Count();

This Function is used to fin the count of array key in the array.

3. Associative array()

Associative array is array that use named keys that you assign to them.

example

<?php

$var2 = array('raj'='123','sekar'=>'213','developer'=>'545','desks'=>'345');

echo $var2['raj']; // output is 123
echo $var2['sekar']; // output is 213
