Need help looping a loop (with for or foreach)

[snowman2344]

I have the following “for loop” I am looking for a single value in an array. It works fine Once.  I want to run this loop for several values. How can I loop the loop every time returning the text output result with the next value in the array?

 

This is the origanal working (Once) code.

 

$str = 'C34';
$ft_key = -1;
for ($i=0;$i<count($your_array) && !$ftf;$i++)
{
$ft_key = -1;
$tmp = explode(', ',$your_array[$i]);//brake apart truck string
$tmp1 = preg_replace ( "/\s\s+/" , " " , $tmp );//remove white spaces
$tmp2 = preg_replace ( "/,/" , "" , $tmp1 );//remove comma
    if (in_array($str,$tmp2)) {
           $ftf = true;
           $ft_key = $i;

    }
}

if ($ftf){
echo "<br>";
echo $str; 
echo " Is on Sceen at → ";echo $abc[$ft_key-7];
}else{
echo $str; echo " is not on a call right now";echo "<br>";echo "<br>";
}

 

What i want to do i look (loop) for $str = array('C34','P123','R421'); and return the rusult for each

Not exactly an expert in php but this should take u home

 

Assuming the array is called $products then

 

for ( $row = 0; $row < 3; $row++ )

{

for ( $column = 0; $column < 3; $column++ )

{

  echo '|'.$products[$row][$column];

}

echo '|<br />';

}

why don't you use array_keys instead? it will be much faster...

Thanks for your input but i am not using mysql for this application

[ToonMariner]

array_keys() is a php function - it returns the keys of an array whose element value is that which you are searching for..

 

the only 'looping' you will have to do is each value you are looking for...

i tryed the following but all the output values are the same (it puts in the first loop values for all) i need to know where to put somting like unset so it can pick up the new loop

 

It sucks not being a guru.

 

$str = array('HZ332','P123','R421');
$ftf = false;
$ft_key = -1;
for ($truck=0;$truck<count($str);$truck++){
for ($i=0;$i<count($your_array) && !$ftf;$i++)
{
$tmp = explode(', ',$your_array[$i]);//brake apart truck string
$tmp1 = preg_replace ( "/\s\s+/" , " " , $tmp );//remove white spaces
$tmp2 = preg_replace ( "/,/" , "" , $tmp1 );//remove comma
    if (in_array($str[$truck],$tmp2)) {
           $ftf = true;
           $ft_key = $i;

    }
}

if ($ftf){
echo "<br>";
echo $str[$truck]; 
echo " Is on Sceen at → ";echo $abc[$ft_key-7];
}else{
echo "<br>";echo $str[$truck]; echo " is not on a call right now";echo "<br>";echo "<br>";
}
}

there are so many ways of achieving this - the best one would be to use something like...

 

<?php
$str = array('HZ332','P123','R421');
$matches = array_intersect($yourarray, $str);
print_r($matches);
?>[/url]

I cannot compare the two arrays because the first array’s strings first need to be taken apart (that is what the code dose that I have).  If one of you gurus has a minute to look at the following code let me know why the values repeat. It loops the correct amount of times but gives me the values for to first value for all of them. I think I need a “UNSET” somewhere maybe?? 

 

 

$str = array('HZ332','P123','R421');
$ftf = false;
$ft_key = -1;
for ($truck=0;$truck<count($str);$truck++){
for ($i=0;$i<count($your_array) && !$ftf;$i++)
{
$tmp = explode(', ',$your_array[$i]);//brake apart truck string
$tmp1 = preg_replace ( "/\s\s+/" , " " , $tmp );//remove white spaces
$tmp2 = preg_replace ( "/,/" , "" , $tmp1 );//remove comma
    if (in_array($str[$truck],$tmp2)) {
           $ftf = true;
           $ft_key = $i;

    }
}

if ($ftf){
echo "<br>";
echo $str[$truck]; 
echo " Is on Sceen at → ";echo $abc[$ft_key-7];
}else{
echo "<br>";echo $str[$truck]; echo " is not on a call right now";echo "<br>";echo "<br>";
}
}

 

Thanks

any ideas ???

[snowman2344]

$str = array('R421','A421','AL421','P421B','P421CR');
foreach ($str as $s){
unset ($ft_key, $i, $tmp);
$ftf = false;
$ft_key = -1;
for ($i=0;$i<count($abc) && !$ftf;$i++)
{
$tmp = explode(', ',$abc[$i]);//brake apart truck string
$tmp1 = preg_replace ( "/\s\s+/" , " " , $tmp );//remove white spaces
$tmp2 = preg_replace ( "/,/" , "" , $tmp1 );//remove comma
    if (in_array($s,$tmp2)) {
           $ftf = true;
           $ft_key = $i;

    }
}

This code runs slow any idea how to speed it up. Takes on average 4 sec to run. ???  ???

[ToonMariner]

don't evaluate count on each loop!!!

 

$stopat = count($abc);

for ($i=0;$i<$stopat && !$ftf;$i++)

{
