How to create array in PHP

Array is used to stores multiple values in one single variable

We can create array by using "array" Keyword

Type of Array

• Indexed arrays - Numeric index
• Associative arrays -Named keys
• Multidimensional arrays - Contain one or more arrays

Indexed Array Examples

Example 1 $color=array("red","Green","Blue"); //echo $color[1]; foreach($color as $val){ echo $val."<br>"; } Example 2 $color=array("red","Green","Blue"); //echo $color[1]; foreach($color as $val){ echo $val."<br>"; } Example 3 $array[0]="Shubham"; $array[1]="Rafiya"; foreach($array as $val){ echo $val."<br>"; } echo count($val); Example 4 $col=array("abc","ccv","dsf"); echo count($col); Example 5 $col=array("abc","ccv","dsf"); $arrlen=count($col); for($i=0;$i<$arrlen;$i++){ echo $col[$i]."<br>"; } Example 6 $col=array("abc","ccv","dsf"); $arrlen=count($col); for($i=0;$i<$arrlen;$i++){ echo $col[$i]."<br>"; }

Associative Array Example

Example 1 $col['Green']="#123"; $col['Red']="#123"; $col['White']="#fff"; echo $col['Red']; Example 2 $col=array("Green"=>"#123","White"=>"#231","Red"=>"#44"); echo $col['Green']; Example 3 $col=array("Green"=>"#123","Green"=>"#231","Red"=>"#44"); echo $col['Green']; Example 4 $col['Green']="#123"; $col['Red']="#123"; $col['White']="#fff"; foreach($col as $val=>$n){ echo $val."<br>"; }

Multi Multidimensional Array Example

Example 1 $arr=array( array(1,2,3), array(4,5,6), array(7,8,9) ); echo $arr[1][2]; } Example 2 $arr=array( array(1,2,3), array(4,5,6), array(7,8,9) ); for($r=0;$r<3;$r++){ for($c=0;$c<3;$c++){ echo $arr[$r][$c]; } echo "<br>"; } }
